MUSIKANTH J:
1 On 26 April 2023, Vandongen J found the respondent to be a high
risk serious offender pursuant to the High Risk Serious Offenders Act
2020 (WA) (Act) and imposed a five-year supervision order containing
some 37 conditions (2023 supervision order).1
2 On 25 September 2024, I found the respondent to have
contravened the 2023 supervision order, rescinded that order, and made
a continuing detention order in its place.2
3 On 7 November 2025, the State applied pursuant to s 64 of the Act
for a review of the continuing detention order.
4 On such an application, the court must consider whether the
respondent remains a high risk serious offender and, if so, whether to
affirm the continuing detention order or, subject to s 29, rescind it and
instead make a supervision order.3
5 For the reasons which follow, I am satisfied:
(1) By acceptable and cogent evidence, and to a high degree of
probability, there is an unacceptable risk that the respondent
will commit a serious offence and that it is necessary to make a
restriction order to ensure the adequate protection of the
community against that risk.
(2) The respondent therefore remains a high risk serious offender.
(3) It is more likely than not that the respondent will substantially
comply with the standard conditions of a supervision order.
(4) A supervision order should be made subject to the conditions
set out in the Annexure.

7 The State also adduced oral evidence from Ms Julie Hasson, a
consultant forensic psychologist, and Ms Chloe Jones, the respondent's
Community Corrections Officer (CCO) until recently.
8 The respondent did not testify but tendered written material
comprising a recent letter from Wungening ReSet Service, a certificate
confirming he had had successfully completed the ReSet Drug and
Alcohol Brief Intervention Program (ReSet program), and a letter and
email in support from his mother and partner respectively.5
9 The court also received correspondence from the High Risk
Serious Offender Unit concerning the respondent's proposed primary
and secondary accommodation in the event of his release on a
supervision order.6
10 No objection was taken to any of the evidence.
Legal Principles
11 In The State of Western Australia v Dempster [No 5],7 I discussed
the legal principles applicable to whether a person is (or remains) a
high risk serious offender and the determination of the appropriate form
of restriction order. I have taken these principles into account in
reaching the conclusions set out at [5] above.
12 I have also had regard to, and gratefully adopt, Tottle J's summary
in The State of Western Australia v Clarke [No 2]8 of the central
principles underpinning the Act following the decision of the High
Court in Garlett v The State of Western Australia.9
Does the respondent remain a high risk serious offender?
13 In determining this question, the court may have regard to any
relevant matter but must consider the matters set out in s 7(3)(a) - (j) of
the Act.10
14 I turn to consider those matters.

Antecedents and criminal record (s 7(3)(g))11
15 The respondent is presently 46 years of age.
16 In The State of Western Australia v Mills [No 2],12 Vandongen J
summarised the respondent's antecedents and criminal history in
considerable detail. I adopt his Honour's summary and do not repeat it.
17 It suffices to note that the respondent has a lengthy criminal record
commencing in his early adolescence, with numerous offences having
involved violence including armed robbery.
Section 74 report and cooperation (s 7(3)(a))
Ms Julie Hasson
18 Ms Hasson, a qualified expert,13 prepared a report as required by
s 74 of the Act14 (Hasson 2026 report).15
19 On 18 March 2026, Ms Hasson interviewed the respondent for
2¾ hours. She recorded that the respondent engaged well in the
assessment process, answered all questions, displayed some insight into
his behaviour in the community, and generally demonstrated sound
emotional and behaviour regulation skills.16
20 Ms Hasson assessed the respondent's risk of future serious
offending using the Hare Psychopathy Checklist, Revised (PCL-R) and
the Historical-Clinical-Risk Management 20, version 3 (HCR-20v3).
21 The respondent's PCL‑R score did not meet the threshold for
psychopathy, consistent with earlier assessments, but remained
indicative of antisocial personality disorder.17
22 The HCR20‑V3 assessed the respondent's risk for violent
reoffending relying on three domains of risk factors: historical, clinical
and risk management.18

23 Ms Hasson identified the overwhelming majority of historical risk
factors as being present, including problems with history of violence,
antisocial behaviour, substance abuse, with poor history of treatment
and supervision response, and with violent attitudes. 19 In contrast, only
one clinical risk factor was found present (recent problem with insight)
although, Ms Hasson noted the respondent had maintained some
improvements in this respect.20 Ms Hasson assessed all relevant risk
management factors to be present.21
24 In the above context, Ms Hasson observed that her 'most
significant concern' was the respondent's ability, motivation and
willingness to abide by conditions of any supervision order, and that the
respondent's behaviour in the community, when subject to the 2023
supervision order, highlighted his inadequate coping and emotional
regulation skills and the importance of him continuing to work on these
matters in counselling.22
25 That said, Ms Hasson accepted that the respondent had developed
some insight into his behaviour and motivations; however, concerns
remained regarding his appreciation of the extent of his risk of
reoffending, the consequences of failing to maintain abstinence, and the
level of commitment required to achieve lasting change. 23
26 Encouragingly, Ms Hasson reported that the respondent had
responded well to individual treatment while in custody, appeared to
recognise his need for assistance in maintaining a prosocial lifestyle
and managing challenges, stress, and new relationships, had distanced
himself from antisocial influences in prison, and had identified a
support network comprising his partner, mother, and daughter. 24
27 At the same time, Ms Hasson considered the respondent's
antisocial personality traits to be a significant contributing factor to his
future compliance with any supervision order, noting his historical
tendency to act in accordance with his own preferences despite the
consequences. In her view, the development of an 'internal locus of
control' would be critical to the respondent's ability to reintegrate
successfully and maintain a prosocial lifestyle.25

28 Ms Hasson also identified possible scenarios for future violent
offending. She opined the most likely scenario would involve the
respondent relapsing into substance use, leading to him committing an
armed robbery or robbery with violence in order to support his drug use
or alleviate financial stress. Ms Hasson explained that such offending
may involve the use of a weapon and threats of harm to gain
compliance. According to Ms Hasson, the potential for harm in such a
case would be significant.26
29 Ms Hasson also outlined two further potential scenarios the first of
which would see the respondent engaging in violent, aggressive or
life-threatening behaviour including actual assault of a stranger or
acquaintance after becoming involved at the behest of an antisocial
acquaintance or loved one. In such a case, Ms Hasson considered a
weapon might also be used if easily accessible.27
30 In her oral evidence, Ms Hasson clarified that such a scenario
would be 'more linked to generalised violence', with the extent of any
resulting injury or harm dependent upon a range of factors. She
considered that there was potential for such future offending to involve
grievous bodily harm, 28 or an act or omission causing bodily harm or
danger, done with intent to harm,29 or with intent to rob, 30 each
constituting a 'serious offence' within the meaning of the Act.31
31 Ms Hasson further observed that in the event of a relapse into
substance abuse, the respondent would likely return to regular
offending and continue to offend until he was apprehended.32
32 However, Ms Hasson described the risk of such offending as
likely to crystalise within 'weeks to months, not necessarily the
following day'.33
33 According to Ms Hasson, indicators that the respondent was
relapsing into an offending cycle would include illicit substance use, an
increased expression of anti-authority and antisocial attitudes,
heightened resistance and hostility towards supervision and monitoring
staff, disengagement from support services, and a rise in stressors. In

such circumstances, she considered that the imminence of the risk of
future violence would increase unless effective measures were
implemented to interrupt the cycle.34
34 Ultimately, Ms Hasson concluded that the respondent would
continue to present a high risk of committing a future serious offence,
involving violence, if not made subject to a supervision order.35
Other assessments (s 7(3)(b))
Earlier reports and assessments
35 Ms Stagg,36 Professor Pyszora,37 Dr Barbas,38 Ms Hasson,39 and
Dr McCann40 prepared reports in respect of the respondent for the
purposes of the restriction order hearing in 2023 and the contravention
hearing in 2024. These reports have been summarised in previous
judgments.41
36 Reports prepared more recently provide a more reliable (and,
indeed, somewhat more positive) picture of the respondent's current
level of functioning.
Ms Caris Hamlett-Waller
37 Since October 2024, the respondent has the benefit of more than
25 individual counselling sessions with Ms Hamlett-Waller,42 a
counselling psychologist with the Forensic Psychological Intervention
Team (FPIT).
38 Ms Hamlett-Waller's reports suggest the respondent has not only
generally engaged well in these sessions but also displayed a level of

insight into his behaviour while he was still subject to the 2023
supervision order.43
39 Relevantly according to Ms Hamlett-Waller, the respondent:
(1) Acknowledged that his previous defiance of the 2023
supervision order stemmed from perceptions of injustice and
long-standing difficulties with authority.44
(2) Whilst initially indicating that he would not agree with a finding
that he was a HRSO, and that he found the conditions of the
2023 supervision order onerous, confusing and restrictive,
nevertheless professed that he would abide by the conditions of
any future supervision order and accept its imposition.45
(3) Expressed a desire to cease using aggression or intimidation to
have his needs met.46
(4) Confirmed that he would be more discerning in his associations
and would focus on prosocial supports to mitigate the risk of
substance use.47
(5) Demonstrated ongoing awareness that his previous negative
behaviours were exacerbated by his antisocial peers.48
(6) Expressed a willingness to engage with FPIT, self-referred to
the ReSet program,49 and verbalised a need for professional
supports to successfully reintegrate into the community.50
(7) Demonstrated a shift in his longstanding antisocial attitudes, Ms
Hamlett-Waller noting that (since the respondent returned to
prison) he remained in a trusted employment position, received
positive reports and had not been subject to any charges.51

(8) Recounted that his reincarceration triggered feelings of failure,
embarrassment and distress.52
(9) Demonstrated a softening in his 'cognitive rigidity', as
evidenced by an increasing willingness to take responsibility for
his past and future behaviour, and an openness to engaging with
a range of staff, indicative of developing insight. 53
(10) As his counselling sessions progressed, began to reflect on his
own internal state and the need to regulate and self-manage.54
(11) Appeared more receptive to empathic confrontation and
feedback on his behaviour (I infer by COMU staff) and,
although at times defensive, was never aggressive or
threatening.55
(12) Acknowledged he wanted to begin expressing his needs to
others rather than building up resentment.56
40 Ultimately, Ms Hamlett-Waller:
(1) Concluded that the respondent has demonstrated a 'sound
capacity for meaningful engagement in counselling',57 whilst
acknowledging that these gains had not yet been demonstrated
over the long term or tested in a community setting.58
(2) Recommended that should the respondent be found suitable for
a supervision order, counselling with FPIT continue, as it would
assist with his reintegration and should focus on reducing his
identified criminogenic needs. 59
(3) Noted the respondent having reported a desire to continue with
his engagement.60
(4) Opined that further treatment in a custodial setting was unlikely
to yield substantial gains for the respondent.61

Ms Emily Selby
41 Ms Selby, a Forensic Psychologist with the Forensic
Psychological Assessment Team, interviewed the respondent in March
2026 for a total of two hours.
42 The respondent also appears to have engaged well with Ms Selby,
who described him as 'cooperative, engaged and articulate'.62 He
demonstrated willingness, motivation, and the capacity to continue to
meaningfully engage with Ms Hamlett-Waller.63
43 According to Ms Selby, the respondent had exhibited positive
behaviour throughout his continuing detention order which he had
continued to maintain in 'a less secure environment'; the Wooroloo
Prison Farm where he has been residing since early February 202664
(although discussions regarding his transfer to a minimum-security
facility had already commenced in October 2025).65
44 Whilst noting these changes have been relatively recent, and not
yet tested in the community 'across time and high risk situations',66
Ms Selby nonetheless opined that the respondent had:67
(1) Demonstrated a good understanding of his risk factors, risk
management plans and insight into the factors which had
contributed to his offending.
(2) Largely abandoned his previously held 'victim stance', having
accepted responsibility for his past behaviour and current
situation.
(3) Articulated insight into his past problems including substance
use, antisocial peer associations, antisocial attitudes and
cognitive distortions, poor emotion management, difficulties
with communication and interpersonal skills, and defiant
response to supervision.
(4) Was able to describe the skills he would utilise to manage these
areas accordingly if released.

(5) Also described appropriate plans to reintegrate into the
community if a supervision order were made.
45 Ms Selby recommended that, if the respondent were released on a
supervision order, he continue individual intervention with
Ms Hamlett-Waller to support him in applying his risk management
strategies in the community and, additionally, engage in counselling
through the Allied Drug and Alcohol Programs and Treatment
(ADAPT) program for further support.68
Ms Chloe Jones
46 Ms Jones in her report among other things records that:
(1) The respondent initially presented as hostile, but has since
become consistently reflective, openly acknowledging the
factors that contributed to his difficulties while subject to the
2023 supervision order.69
(2) The respondent acknowledged he had deliberately engaged in
defiant behaviour as a 'protest'. 70
(3) In more recent sessions, the respondent has been receptive to
feedback, and able to articulate ways he can increase personal
responsibility and autonomy. 71
(4) The respondent has not only avoided the attention of prison
staff for adverse behaviour, but demonstrated 'above and
beyond' conduct, and been described as setting a 'positive
example' for other prisoners.72
47 In relation to programmatic intervention, Ms Jones reports that the
respondent:
(1) Has maintained engagement with insight-oriented therapy with
the FPIT.73
(2) In September 2025, 'self-referred' himself to the ADAPT
program; a collaborative initiative between Holyoake and
Cyrenian House (alcohol and other drug services), designed to

support individuals in custody affected by alcohol and drug use,
which commences three to six months prior to release.74
(3) As at the time of her report, had participated in three sessions
with a Cyrenian House counsellor who reported the respondent
as having presented as engaged, was cognisant of his alcohol
and drug triggers, and expressed a willingness to implement
abstinence strategies.75
(4) Would, if released on a supervision order, be eligible for six
sessions through the ADAPT program as well as additional
community-based supports if requested.76
(5) In February 2026, also commenced engagement with the ReSet
program, which provides case management, counselling, and
group work for six months prior to release until 12 months
post-release;77 Ms Jones noting that the respondent's
engagement to date has been appropriate and constructive, and
that ReSet has developed a support plan with him.78
48 If the respondent were released on a supervision order, Ms Jones
reports that he proposes residing with his partner and her father, as well
as with his mother at a separate address.79 He seeks to reside at both
locations to allow for flexibility, given the distance between them.80
49 According to Ms Jones, the respondent also expressed an intention
to limit his social interactions beyond his immediate family, and has
consistently expressed a desire to maintain a pro-social lifestyle stating
that 'prison is not for me anymore'.81
Propensity to seriously reoffend (s 7(3)(c))
50 A person has a 'propensity to commit serious offences in the
future' if they have an inclination, tendency, or disposition to commit
serious offences, be it generally, in a particular way, or against a
particular type of victim.82

51 As Vandongen J noted, the respondent has, since 1992, committed
a significant number of robbery, attempted robbery, and armed robbery
offences; a history which 'clearly establishes that [the respondent] has a
propensity to commit offences of robbery, or robbery-related
offences'.83
52 His Honour's conclusion is, with respect, amply supported by
views expressed by Professor Pyszora,84 and Ms Hasson.85
Pattern of offending (s 7(3)(d))
53 A 'pattern' as it pertains to behaviour, is recurrent way of acting by
an individual or group towards a given object or in a given situation.86
54 The respondent's significant number of charges and convictions
for violent behaviour evidences a clear pattern of violence, which has
escalated over time,87 although, as Ms Hasson observes, the
respondent's violent behaviour has shown some diversity. In this
regard, as Ms Hasson explains, the respondent:88
… has used various weapons as well as his own body when assaulting
others. He has targeted strangers and acquaintances. Some of [the
respondent's] violent acts have been reactive, motivated by anger and
other emotions, cognitions and beliefs. Other episodes of violence have
been instrumental and motivated by financial strain and a desire to
obtain needs and wants. The severity of violence perpetrated by [the
respondent] has varied, resulting in physical injury to some victims as
well as psychological harm to others. In many if not all instances [the
respondent] has been the instigator/aggressor.
Efforts to address cause(s) of offending behaviour, rehabilitation,
treatment and effect (s 7(3)(e) - (f))
55 Prior to his release into the community on the 2023 supervision
order, the respondent participated in a substance use program and skills
training for aggression control in 1999, a Pathways program in 2011, a
violent offender treatment program in 2016, and the Think First
program in both 2017 and 2019 (which he did not complete on either
occasion due to personal stressors), as well as 13 self-funded voluntary

sessions at the Whitehaven Clinic in 2021 to address his substance
use.89
56 Regrettably, it appears that the respondent's engagement in these
programs did not result in lasting behavioural change.
57 However, as noted, since the respondent's return to custody, his
engagement in counselling with Ms Hamlett-Waller has been sustained
and meaningful.
58 Ms Selby reports that the respondent consistently attended his
sessions with Ms Hamlett-Waller punctually and in a prepared state,
and was described overall as 'an engaged participant', 90 with both Ms
Selby and Ms Hamlett-Waller considering his participation to have had
a positive effect.
59 Indeed, according to Ms Hasson, the respondent had 'nothing but
positive feedback' regarding his counselling sessions with
Ms Hamlett-Waller, and was able to identify the areas they had
addressed and what he had gained from those sessions, which was
described as 'really reassuring'.91
60 In addition, as noted, the respondent self-referred to the ADAPT
program, in relation to which he was described as presenting as
engaged, cognisant of his triggers and willing to implement abstinence
strategies, and more recently to the ReSet program, where his
participation was likewise described in positive terms.
Risk and need for community protection (s 7(3)(h) - (i))
61 The unchallenged evidence of Ms Hasson is that the respondent
continues to pose a high risk to the community of committing a serious
offence if not made subject to a restriction order.
62 Although the evidence overwhelmingly supports an inference that
the respondent has made considerable positive strides towards
developing insight and coping skills over the course of the past
20 months, his gains are recent and have not been tested over time and
in high-risk situations.
63 In all the circumstances, I find there is a high risk that the
respondent will seriously reoffend if not made subject to a restriction

order, and that there is a need to protect members of the community
from that risk.
Other relevant matters (s 7(3)(j))
64 I do not consider there to be any other materially relevant matters.
Determination
65 At the hearing, the respondent accepted that there was a sufficient
basis for the court to find that he remained a high risk serious offender.
66 The contention was well made.
67 For the foregoing reasons I am satisfied, by acceptable and cogent
evidence, and to a high degree of probability, that the statutory test is
met.
68 Accordingly, I am satisfied that the respondent remains a high risk
serious offender.
What order should be made?
69 The principles relevant to determining what order should be made
are summarised in, among other decisions, The State of Western
Australia v Dempster [No 5].92
70 Mindful of those principles, and noting I may not make a
supervision order unless the respondent has satisfied me it is more
likely than not he will comply with the standard conditions of such an
order, I have considered this question by reference to the factors which
appear relevant to its assessment in the present case.93
71 Having carefully considered these factors, and for the following
reasons, I am satisfied on the balance of probabilities that the
respondent will substantially comply with the standard conditions if
released on a supervision order.
72 First, the respondent has, over a sustained period of many months,
engaged in over 25 individual counselling sessions Ms Hamlett-Waller.
Through his participation, he has achieved significant treatment gains
across all identified areas of need, having demonstrated a capacity for

identifying his risk factors, and risk management plans for
implementation of strategies for behavioural regulation.94
73 Secondly, over this period the respondent has developed a
relationship of trust and rapport with Ms Hamlett-Waller, to whom he
reportedly considers he 'could talk … about anything'. 95 If released on
a supervision order, it is envisaged that he would continue counselling
with Ms Hamlett-Waller, initially on at least a weekly basis (and later
likely fortnightly). 96 I infer that the positive relationship he has
developed with Ms Hamlett-Waller would provide a foundation for him
to articulate his stresses and concerns while in the community, with the
potential for an even greater positive effect.
74 Thirdly, the respondent has demonstrated a clear willingness to
implement abstinence strategies learned through the ADAPT program,
having also engaged constructively and successfully with ReSet which,
as noted, has developed a support plan to assist him if released on a
supervision order.
75 Fourthly, during his time in custody the respondent continued to
self-report abstinence for all illicit substances and to submit he was
distancing himself from those involved in the illicit substance trade.
Both urinalysis for illicit substances and breath analysis for alcohol
have returned negative results.97
76 The respondent has also indicated he plans to continue with his
opiate substitution therapy (OST) from which he has derived benefit
over the past two years. 98
77 According to Ms Hasson, this treatment has been integral in
assisting the respondent to abstain from drug use in custody, and he has
recognised the importance of its continuation in any transition to life in
the community.99
78 Ms Hasson further explained that opiates had, in the past, been one
of the respondent's primary difficulties, that he was happy with his OST

treatment (in the form of a monthly injection), felt it had been working
well, and had very positive views about its benefits.100
79 Noting the above matters, I am satisfied there are measures that
will be in place to ensure substantial compliance with the standard
conditions of a supervision order.
80 Fifthly, Ms Hasson, Ms Hamlett-Waller, and Ms Selby all observe
that the respondent has expressed an intention not only to remain
abstinent from drugs101 but also to abide by the conditions of any future
supervision order.102
81 I consider it more than reasonably open to conclude that the
respondent has undergone a significant change in attitude since the
continuing detention order was made; having not only verbalised an
acceptance of personal responsibility for compliance with the terms of
any future supervision order but also now shown at least a degree of
insight into his behaviour while he was subject to the 2023 supervision
order.
82 Sixthly, as noted, the respondent has demonstrated positive
behaviour throughout the period of his continuing detention order.
According to Ms Jones he has been described as going 'above and
beyond' and setting a 'positive example' for other prisoners.103 This is
reflected in his transfer from maximum to minimum security; an
outcome said to have occurred 'for the first time' in his case.104
83 Seventhly, the respondent is in the fortunate position of having no
fewer than two suitable accommodation options available should he be
released into the community: a primary residence with his partner, and
a secondary residence with his mother. Both have been described as
'significant supports' for the respondent.105
84 Eighthly, while the respondent's capacity to comply may be
undermined by his antisocial personality traits and entrenched

Page 19
antiauthoritarian attitude,106 he now appears to have demonstrated the
ability to identify and challenge these views.107
85 Finally, the State has proposed a series of conditions to which any
supervision order would be subject. The proposed conditions are
supported by Ms Hasson, with many evidently designed to assist in
mitigating the risk of the respondent entering another offending cycle.
86 Having considered all the above matters, I am satisfied that the
prospect of the respondent substantially complying with the standard
conditions of a supervision order no longer hinges merely on a
combination of words and hope.108
87 Moreover, as counsel for the State observed in closing:109
[The respondent] now knows what is likely to happen if he doesn't
[substantially comply with a supervision order]. He has spent now a
considerable period of time in custody, for which he was both sentenced
to a term as well as on the continuing detention order. So he's under no
illusion as to the seriousness that the court takes these matters and the
potential outcomes for him if he doesn't comply.
88 In all the circumstances, I am satisfied that it is more likely than
not that the respondent will in fact substantially comply with those
conditions.
89 In reaching this conclusion, I remain cognisant that the Act's
protective purpose does not require the risk to the community to be
reduced to zero.
Duration of supervision order
90 Initially, Ms Hasson opined that the appropriate duration of any
supervision order be five years. However, in her oral evidence, she
expressed the view that a period of two to three years would be
suitable, and that, if the respondent were to successfully navigate a
supervision order for two years, he would be 'well placed to continue
on and reduce his risk of committing a serious offence in the future'.110

91 The respondent accepts that, on this evidence, it is open to the
court to make a supervision order of such duration.111 I agree.
Conclusion
92 For the above reasons, I make a supervision in relation to the
respondent for a period of two (2) years from 18 June 2026, being a
date not earlier than 21 days from the date this Order, subject to the
conditions which I now publish.
