APPEARANCES &
REPRESENTATION:
At the parties’ request, this matter was heard and determined
on the papers pursuant to s 32 of the Queensland Civil and
Administrative Tribunal Act 2009 (Qld).
REASONS FOR DECISION
What is the application about?
The Boaters say that use and enjoyment of their urban property is impacted by
substantial, ongoing, and unreasonable interference by leaf and flower litter from a
Tipuana tree1 (the Tree) situated on the adjoining land owned by their neighbours, the
Kwoks.
On 18 December 2020, the Boaters applied for orders requiring that branches of the
tree be removed or pruned at the Kwoks’ cost.2
In a response filed 12 January 2021, and in an application for miscellaneous matters
seeking strike out filed 27 January 2022, the Kwoks say the Tree is safe, contained
wholly within their land, that no works or orders are necessary, and that the Boaters’
application should be dismissed.
The parties consented to a decision ‘on the papers’ on the application for strike out,
and, if strike out is refused, on the application for a tree dispute. I have dismissed both
the strike out application and the application for a tree dispute for the following
reasons.
What laws apply?
Jurisdiction over tree disputes
Chapter 3 of the Neighbourhood Disputes (Dividing Fences and Trees) Act 2011 (Qld)
(NDA) applies to trees situated on land recorded in the freehold land register3 with
some exception.4
A “tree” is defined in section 45 of the NDA and includes any woody perennial plant
and any plant resembling a tree in form or size, which would include a plant classified
as a ‘weed’.
Tree keepers are responsible for their trees.5
1 Also known as the rosewood, tipu tree or ‘yellow jacaranda’.
2 Application for a tree dispute filed 19 December 2020, Part F, Question 39.
3 Neighbourhood Disputes (Dividing Fences and Trees) Act 2011 (Qld) (NDA), s 42(1)(a).
4 Ibid, s 42(3)&(4).
5 Ibid, s 52.
-- 2 of 10 --

Under section 48(1)(a) of the NDA a “tree keeper” is, if the land on which the tree is
situated is a lot recorded in the freehold land register under the Land Title Act 1994
(Qld) (LTA) the registered owner of the lot under that Act, and under section 49 a
“neighbour” is, if the land affected by the tree is a lot recorded in the freehold land
register under the LTA, the registered owner of the lot under that Act.
I am satisfied from filed title searches that the Kwoks are “tree-keepers” for the
purpose of this application and that the Boaters have standing to bring the application
as their “neighbours”.
Section 65 of the NDA prevents the Tribunal from making an order in relation to trees
unless the applicant neighbour:
(a) has made a reasonable effort to reach agreement with the tree-keeper;
(b) has taken all reasonable steps to resolve the issue under any relevant local law,
local government scheme or local government administrative process;
(c) to the extent the issue relates to the land being affected because branches from
the tree overhang, cannot engage their common law right of abatement and the
process in part 4 to resolve the dispute; and
(d) has given the copies of the application under section 63, other than to the extent
the requirement to do so has been waived.
I am satisfied that the parties attempted to informally mediate the tree dispute (by
having discussions and getting works on tree works that might be required) prior to
the filing of the application, that these were a reasonable effort to resolve the dispute
and that the requirements of section 65 have otherwise been met.
Relevant to the Boaters’ application:
(a) Under section 46 of the NDA:
Land is affected by a tree at a particular time if—
(a) any of the following applies—
…(ii) the tree has caused, is causing, or is likely within the next 12
months to cause—
…(C) substantial, ongoing and unreasonable interference with the
neighbour’s use and enjoyment of the land.
(b) Under section 66(2) of the NDA, the Tribunal can make orders in relation to
trees to remedy, restrain or prevent substantial, ongoing, and unreasonable
interference with the use and enjoyment of the neighbour’s land.
When assessing unreasonable interference, the Tribunal may have regard to:6
(a) anything other than the tree that has contributed to the interference;
(b) steps taken by the parties to rectify or reduce the interference;
(c) the size of the neighbours’ land; and
(d) whether the tree existed before the neighbours purchased the land.
6 Section 75, ibid.

Strike out applications
The objects of the Queensland Civil and Administrative Tribunal Act 2009 (Qld)
(QCAT Act)7 include to have the Tribunal deal with matters in a way that is
accessible, fair, just, economical, informal, and quick, and, to that end, section 4 of
the Act requires the Tribunal, among other things, to:
(a) encourage the early and economical resolution of disputes before the Tribunal;8
and
(b) ensure proceedings are conducted in an informal way that minimises costs to
the parties and is as quick as is consistent with achieving justice.9
Section 62(1) of the QCAT Act permits the Tribunal to give a direction at any time in
a proceeding and to do whatever is necessary for the speedy and fair conduct of the
proceeding. Proceedings may be finally determined, or interlocutory applications
decided upon the written submissions of the parties ‘on the papers’, without those
parties or their representatives appearing at a hearing.10
Under section 47 of the QCAT Act, the Tribunal can dismiss a proceeding if, among
other things, it considers the proceeding to be frivolous, vexatious, misconceived or
lacking in substance.
However:
(a) The power to strike out ought only to be exercised “sparingly” and “when a
claim is groundless or futile”.11
(b) In considering a strike out application, the evidence should be weighed to reach
a conclusion about whether the applicant has an arguable case.12
(c) A lack of any cause of action must be very clear,13 and the Tribunal ought to be
satisfied to a “high degree of certainty about the outcome” to strike the
proceeding out.14
(d) Summary dismissal should not be granted simply because it appears an
applicant is unlikely to succeed on an issue of fact, in circumstances where there
are factual issues in dispute and capable of dispute.15
The applicants’ case
The Boaters rely on the following evidence:
(a) Extract from the Brisbane City Council website on weed identification dated 7
December 2020 indicating that the Tree is considered a class ‘R’ weed which is

not notifiable, but the intention is to reduce populations of the weed in the urban
environment.
(b) A quote from Brisbane Treeworks dated 27 November 2020 that refers to having
the left-hand leader removed and cut back to the main growth point at a cost of
$1,870 including GST.
(c) Various colour photographs evidencing leaf litter to the pool at 8:31am, 8:41am,
12:56pm, 1:23pm and 5:30pm on 15 November 2020 before and after cleaning.
Leaf litter largely comprises yellow flowers typical of the Tree.
(d) Colour photographs taken on 16 November 2020 at 8:44am, 9:01am, 5:13pm,
and further photographs taken on 17 November 2020 showing an example of
the accumulation of flower litter if daily cleaning and multiple cleans are not
done throughout the day to keep the pool clean.
(e) Photographs showing examples of the flower litter covering the decks as well
as the pool.
(f) Colour photographs indicating that if daily cleaning is not maintained the
flowers stick to the bottom of the pool, causing staining on the pool floor.
(g) Colour photographs that indicate that if the deck is not maintained the flowers
can dry and stick to the deck when mixed with pool water.
(h) Colour photographs showing context/position of the Tree from the street front
and its proximity to the neighbouring pool.
The Boaters say that:
(a) Prior to the filing of the application the Kwoks sought three quotes and arborists’
advice following a discussion had between the parties regarding the Tree.
(b) The Boaters didn't see the quotes or speak with the first two arborists but met
with the third as the Kwoks invited them onto the property while the arborist
was there to discuss their advice.
(c) The third arborist advised the Kwoks that the two top branches leading towards
the Boaters’ property, which were approximately two to three metres in length
each could be pruned and suggested that the Boaters install a shade sail across
the pool and leaf blow the collected leaves back onto the Kwoks’ property to
manage the leaf and flower litter from the Tree.
(d) The Kwoks suggested that they would share in the cost of the installation of the
shade sail, however the Boaters were not comfortable having anchoring points
installed to support the sail and did not wish to incur any cost to install the shade
sail, irrespective of whether it was shared or not.
After that, the Boaters engaged Treeworks to give their opinion, and say that opinion
was that removing the top two branches would have no benefit in reducing the leaf or
flower litter. They said the left-hand leader growing towards the Boaters’ property
should be cut back to the main growth point and that this would leave 50% of the Tree
remaining which would still provide shade, with a 50% reduction of litter to the pool.
This was not accepted by the Kwoks.
The Boaters say that the Tree is fast growing and deciduous, dropping leaves for 2
months and flowers for another 2 months of the year.

Additional submissions from the Boaters include:
(a) Text message exchange between the parties regarding the various arborist visits
new line Additional photographs of the tree taken on one December 2020 and
two January 2022 showing comparison images depicting the growth of the tree
over one year.
(b) That the Tree will surpass their boundary within the next year because it exceeds
2.5 metres and therefore, they cannot exercise their right of abatement with
respect to overhanging branches when it happens.
(c) Photographs from 28 October 2021 showing the use of a pool cover and flowers
falling onto the pool cover, 26 October 2021 and 23 August 2021 showing
flowers falling to the bottom of the pool in respect of which the applicant say
they need to use their pool cleaner and then scrub by hand to remove the staining
from the pool.
(d) A web extract from O’Brien’s Tree Care & Landscaping indicating that the Tree
is a declared weed previously planted as an ornamental and shade tree however
now posing an environmental threat to woodlands, riverbank vegetation
communities and urban bushland. It also says that council’s policy is to reduce
the number of these past trees, so tree removal should be considered.
(e) Extract from Brisbane Treeworks identifying the Tree was one of the “worst
trees to plant in your home” as they grow to approximately thirty metres wide
and twenty metres high, making them a great shade tree but in a yard rendering
it likely too big to handle.
(f) Extract from Aussie Tree Solutions website indicating similarly that the trees
can grow to twenty metres high and aren't suitable for a backyard garden, again
saying its best to have these trees removed.
(g) Extract from Trees, Palms & Stumps website that identifies the Tree as one of
the five worst trees to plant near a house.
The Boaters acknowledge that ‘normal tree litter’ is not typically classed as substantial
and has not in other cases amounted to the requisite level of interference to warrant
tree orders being made. However they say that their photographic evidence supports
their submission that the leaf and flower litter dropped in their yard for four months
of the year is not normal tree letter because it requires them to clean the pool three
times a day during this four-month shedding, which is an unreasonable amount of
daily cleaning impact negatively their enjoyment of their land and prevents them from
spontaneously using the pool without having to factor in cleaning time prior to using
it.
The Boaters say they have taken various steps to try and rectify the problem
themselves including cleaning frequently and using a pool cover. However, if they
do not remove the leaf litter, this results in mould on the pool cover.
They say the Kwoks have other trees providing shade in their backyard and the
reduction of the left-hand leader from the Tree will significantly reduce the leaf and
flower litter in their pool while still allowing the Kwoks to keep most of their tree and
shade from other trees in their yards. The Boaters also say that Brisbane Treeworks
indicated that the removal of the left leader would not impact the health or safety/
stability of the tree because it is a well-established tree.

The Boaters say that usual work from “expected inference” by the Tree should amount
to weekly maintenance including leaf skimming, weekly maintenance cleaning the
bottom of the pool, daily running of the pool filter and weekly cleaning of the skimmer
box, at an average of one hour per day. However, four months of the year they say
they experience “substantial and unreasonable interference” as they are required to
undertake three times daily leaf skimming, two to three times daily maintenance
clearing leaf and flower litter from the top and bottom of the pool, daily running of
the pool filter with two daily cleanings of the skimmer box so that it does not block
the flow of water in the pool pump, amounting to approximately five and a quarter
hours per week.
The respondents’ case
In response submissions the Kwoks say:
(a) The Tree does not pose a safety issue, overhang the common boundary, or
interfere with the applicants’ property.
(b) The Tree existed before the pool was constructed and before the Boaters
acquired the land.
(c) The Kwoks experience enjoyment from the garden shade for playing, rest,
privacy from their rear neighbour and native wildlife on account of the Tree.
(d) The Kwoks purchased their property because of the aesthetic beauty of the
established Tree.
(e) Excessive pruning of the Tree would impact their enjoyment of their land,
diminish their property value, affect the aesthetics of the Tree and remove
wildlife habitat.
The Kwoks attached photographs of their rear yard upon which they indicated what
the impact would be if the left leader of the tree was removed.
They also attached an Energetic Tree Lopping quotation dated 19 November 2020
which provided a quote to cut the major right-hand limb going towards the Boaters’
house down to the fork, same with the smaller left hand limb, to reduce growth
towards house, reduce overhang into back neighbours, at a cost of $1,210.
No tree assessment
Tree assessors typically assist the Tribunal by providing expert evidence.16 The
assessor will inspect the tree/s and properties the subject of the dispute and provide a
report that outlines solutions to the issues raised in the application from which the
parties will be invited to reach agreement, or the matter will proceed to a hearing on
the basis that the tree assessor’s evidence will be the only expert evidence permitted
at the hearing.17
At a directions hearing the parties were given an opportunity for the Tribunal to
appoint a tree assessor to assess the tree and the impact it was having on the Boaters’
property but both parties declined, preferring a decision to be made on the papers
based upon evidence and written submissions of the parties themselves.

Consequently, there is no expert arborists’ evidence before the Tribunal.
Each party provided quotes for pruning but the quotes do not offer an opinion as to:
(a) whether the pruning is necessary,
(b) whether and how pruning would impact the health and structural stability of the
Tree, or
(c) whether and how pruning would reduce the leaf and flower litter experienced
and complained of by the Boaters.
Findings and Decision
The strike out application
It is a dispute of fact as to whether the impact of the leaf litter upon the Boaters’ use
and enjoyment of their land amounts to substantial, ongoing, and unreasonable
interference. As mentioned, this requires an assessment of the circumstances
including factors other than the tree contributing to the interference, steps taken to
reduce the interference, the size of the land and whether the tree existed before the
neighbours purchased the land.
The applicants face a daunting prospect of establishing substantial, ongoing, and
unreasonable interference by leaf litter alone. As Senior Member Brown observed in
Finch v Grahle [2017] QCAT 80:18
Generally speaking, leaf litter will not, of itself, be sufficient to constitute a
substantial, ongoing and unreasonable interference with the use and enjoyment
of land.
However, it is impossible to say, with the required high degree of certainty19 that their
claim is “groundless or futile”20 before their evidence of interference and the
surrounding circumstances regarding the Tree and the property impacted by it are
assessed and findings of fact made.
There are factual issues in dispute and capable of dispute and in those circumstances
summary dismissal is not warranted.21 The application to strike out is dismissed on
that basis.
The application for a tree dispute
As mentioned, land is affected by a tree at a particular time if the tree has caused, is
causing, or is likely within the next 12 months to cause substantial, ongoing and
unreasonable interference with the neighbour’s use and enjoyment of the land.22

The Tribunal can make orders in relation to trees to remedy, restrain or prevent that
substantial, ongoing and unreasonable interference with the use and enjoyment of the
neighbour’s land.23
I accept the photographic evidence that leaf and flower litter from the Tree
inconveniences the Boaters and interferes with their use and enjoyment of their land.
Four months in each year they are required to clean their pool and deck of leaf and
flower litter more frequently that would otherwise by the case so that they can swim
in their pool and to avoid staining of the pool and deck and damage to their pool pump
from litter build-up. But is this interference substantial, ongoing, and unreasonable?
Turning to the section 75 factors:
(a) It does not appear that anything other than the Tree that has contributed to the
interference, other than the decision (made prior to Boaters’ ownership of the
land) to construct the pool at the adjoining boundary of land that featured a large,
established tree.
(b) The Boaters have taken some steps to reduce the interference using a pool cover
but have not undertaken further steps such as using a shade-sail, even with the
offered contribution to the cost from the Kwoks.
(c) The Boaters’ land is approximately 405m2, so quite small.
(d) The Tree existed before the Boaters purchased the land.
The dropping of leaves, flowers, fruit, seeds or small elements of deadwood by urban
trees ordinarily will not provide the basis for ordering removal of, or intervention with,
an urban tree.24
In Graham & Ors v Welch,25 Atkinson J of the Court of Appeal said:
Trees and bushes are commonplace and desirable attributes of homes in
residential areas. It is not possible to have the Australian gumtree without the
possibility of gumnuts falling or a Casuarina without the possibility of seed
pods, or many common native or exotic trees or shrubs which flower and then
produce nuts, berries, seeds, or seed pods.
Muir J, agreeing with Atkinson J observed that:
[1] …Trees on suburban residential allotments contribute significantly to their
amenity and that of the surrounding neighbourhood. Their value is not merely
aesthetic in nature, although that is obviously important in itself. As well as
providing shade and shelter, they can act as wind breaks, help retain soil,
provide or improve privacy and attract birds and other wildlife.
[2] Their manifold benefits do not come without disadvantages, as many
neighbourhood disputes over trees will testify. A householder who may not
object to the shade provided by a neighbour’s tree in summer may be less
enamoured of its shade in winter, its leaves on lawns, pathways and in guttering
and its roots in pipes and foundations. Nevertheless trees, often too large for,
and otherwise unsuited to their position if measured by the standards of
landscape architects, are part and parcel of Queensland suburbia. Residents of

Queensland are generally aware of their benefits and disadvantages and of the
hazards which they pose.
The evidence before the Tribunal is that:
(a) The interference occurs four months out of the year – whilst it is ongoing in the
sense that it repeats, annually, it is not a continuous interference nor is it for
most of the year. The interference to the Boaters is the requirement that they
clean and maintain their pool and deck more often than they would otherwise
need to during those four months. This is inconvenient but does not go beyond
that.
(b) The staining and impact on the deck, pool and pool cover does not amount to
serious damage to property. Nor is there a report or evidence with respect to any
likelihood that the leaf and flower litter will cause functional damage to the pool
pump or filter. Whilst there are remedies in the NDA for the likelihood of
serious damage, that standard is not met on the evidence before the Tribunal.
(c) The Tree is a weed and not ideal for urban lots, however, it was present and
well-established when the Boaters purchased their home. They say “no one
could ever foresee the amount of leaf litter that would blow into our year every
year, four months of the year” but I would have expected that a pre-purchase
inspection and identification of the tree might have foreseen exactly that.
(d) According to the Kwoks, the Tree was a drawcard when they purchased their
home, and they enjoy the privacy and shading the Tree provides them, although
the Boaters point out that there are other trees in their yard that offer shade.
There are no arborists reports that identify the age or size of the Tree and the pruning
quotes do not comment on whether the different methods of pruning quoted will
resolve the leaf litter issue, nor do they outline the impact the pruning will have on the
Tree. Even if I was inclined to make tree orders, I could not confidently do so given
that dearth of evidence.
In any event, to make tree orders, I am required to be satisfied, on the balance of
probabilities, that the leaf litter deposited by the Tree creates an interference to the
Boaters that is substantial, ongoing, and unreasonable.
The requisite standard of proof is the balance of probabilities, albeit to a sliding scale.
According to Justice Dixon in Briginshaw v Briginshaw26 “reasonable satisfaction”
should not be provided by inexact proofs, indefinite testimony, or indirect references.
I am not satisfied on the evidence before the Tribunal that the Tree is causing an
interference to the Boaters that is substantial, ongoing, and unreasonable to justify the
making of tree orders. The application for a tree dispute is dismissed on that basis.
