Neighbourhood Disputes (Dividing Fences and Trees) Act
2011 (Qld), s 46, s 66, s 73, s 75
REASONS FOR DECISION
[1] Mrs Andrews shares a common boundary with her neighbours Mark Gardner and
Andrew Gardner. She applies to the Tribunal to order the removal of two Chinese Elm
Trees (‘tree’) situated on the Gardners’ land. Both Elms have grown together in unison
and their root systems and upper canopies have developed in conjunction with each
other. Accordingly, in this decision, it is convenient to treat both Elms as a single tree.
[2] There is an existing timber fence and an existing retaining wall between Mrs
Andrews’ land and that of the Gardners. A cadastral survey conducted by Trilogy
Survey Solutions (‘Trilogy’) reveals the following:
(a) the existing fence is situated entirely on Mrs Andrews’ land.
(b) the existing retaining wall is partially on her land.
(c) the base of the tree is predominantly located on the Gardners’ land, but it crosses
the common boundary into Mrs Andrews’ land.
[3] Mrs Andrews moves for the tree to be removed because, on her account, it sheds an
excessive quantity of leaves and branches into her property. She also contends that
sap from the tree causes black sooty mould to accumulate on, and damage, furniture
in her yard. Further, Mrs Andrews wants to landscape her backyard with gardens,
construct a retaining wall, and erect a new timber fence. She claims that the tree’s
positioning on the common boundary prevents her from doing those things.
[4] In written submissions to the Tribunal Mrs Andrews claims:
(a) the tree’s canopy extends more than five meters over her property and most of
its trunk and limbs are within her property.
(b) constructing her pool as far away as possible from the tree has not ameliorated
the excessive quantity of leaves that fall into it.
(c) the tree’s roots have ruptured the bottom of the existing fence. She lodged a
separate application in the Tribunal (Q759-23) seeking a new dividing fence.
(d) the tree’s invasive roots prevent her from installing garden beds, constructing a
retaining wall, and landscaping her land.
(e) the tree’s extensive and invasive root system combined with the existing
restraining wall make it impossible for a fencer to install safe and secure
footings which are necessary to erect a fence.
(f) the tree drops its full canopy each year between April and August. It has been
necessary for her to dispose of furniture in her yard which has rotted from
exposure to falling leaf litter from the tree. The leaves do not break down and
must be physically removed, which she finds onerous.
(g) in November 2022 she exercised her common law right of abatement in respect
of the tree by pruning it and removing its roots up to the common boundary.
Taking those steps has not noticeably reduced the quantity of leaf litter that falls
into her yard.
-- 2 of 10 --
3
(h) the tree provides no privacy benefits because it has an umbrella shaped canopy
which is more than eight metres above the ground.
(i) the shade that the tree casts, and the black sooty mould it produces, has caused
the existing fence to degrade substantially over the past ten years. The fence is
covering in mould and moss, and it is rotting. It is also leaning into her property.
Constructing a new fence would likely require constant Tribunal involvement
every time it fell into disrepair due to the tree.
The Gardners’ Submissions
[5] The Gardners oppose the removal of the tree. They deny that the tree produces
excessive leaf litter or that it damages Mrs Andrews’ pool equipment and furniture.
They argue that the Tribunal should make orders requiring them to maintain and prune
the tree, rather than ordering its destruction.
[6] Further, they contend that a new fence and retaining wall can be constructed provided
accommodations are made for the tree. They contend that a sufficient dividing fence
as defined in Neighbourhood Disputes (Dividing Fences and Trees) Act 2011 (Qld)
(‘the Act’) is between 500mm and 800mm high, which would allow for a chain wire
fence to be built on the common boundary. Alternatively, they contend that a timber
fence, with scalloping around the parts of the tree that intersect with the common
boundary, is a suitable compromise.
[7] The Gardners agree that the existing retaining wall encroaches on Mrs Andrews’
property and should be removed. However, they contend that the extent of the
encroachment is only 200-300mm, not 1000mm.
[8] The Gardners profess to deriving significant enjoyment from the tree. They claim it
provides significant physical and visual amenity due to the shade it casts and by
softening the visual impact of surrounding structures. They argue that the tree supports
the local ecosystem and wildlife.
Tree Assessors
[9] The Tribunal benefited from the reports of two tree assessors. They were:
(a) Stephen Richards; and
(b) Jason-jay Naylor.
Tree Assessment Report of Steven Richards
[10] In a Tree Assessment Report dated 30 October 2023, Mr Richards stated:
(a) the subject trees have grown together in unison. Their root systems and upper
canopies have developed in conjunction with each other. For the purposes of his
report, he intends to consider the trees as a single tree unit with two main leaders.
(b) the stem of Tree No. 2 leans slightly to the north and intersects with the dividing
fence approximately 200ml above ground level.
(c) the subject tree is a declared Category 3 Restricted Matter (Biosecurity Act 2014
(Qld)). The restriction is limited to sale and distribution and is not a restricted
category.
(d) the subject tree is deciduous, which means it loses it leaves in winter.
-- 3 of 10 --
4
(e) the subject tree is estimated to be 50-60 years of age.
(f) when he inspected the tree, the branches of its northern canopy had been
completely pruned back to the trunk effectively removing all overhanging limbs
to an approximate height of 10m above ground level. The pruning did not
conform to Australian pruning standards because more than 20% of the canopy
was removed for only one objective.
(g) Dividing fences can be constructed around trees without damaging them or
compromising the property boundaries. The report contained example
photographs.
(h) Mrs Andrews removed significant structural and transport roots when the
landscaped the rear of their property. The structural integrity of the tree is not a
primary concern but the decline in its health is of grave importance.
[11] Ultimately, Mr Richards recommended the retention of the tree and that a Min. AQF
level 5 arborist with experience in construction damage and plant health care programs
should be engaged to design and implement a program that address the issues caused
by the damage to the tree. Methodologies include:
(a) vertical coring in conjunction with compost repatriation;
(b) horticultural watering;
(c) fortnightly visitations; and
(d) installation of a dynamic cabling system in the upper canopies of both trees.
[12] Notably, Mr Richards opined that it was important to note that the health of Tree No.
2 must be closely monitored. If decline persists for more than a two-year period, then
the engaged consultant must make the decision for removal. The removal of tree No.
2 necessitates the removal of Tree No. 1 due to their association.
[13] He also stated that in the event the subject trees’ health can be restored an
Arboricultural Impact Report should be commissioned to implement a methodology
to assist with fence construction.
[14] The lack of consultation with AS4970-2009 Protection of trees on Development sites
has given no methodology for contractors to follow which would mitigate tree
damage, potentially undermining continued tree health and viability in the landscape.
Report of Jason-jay Naylor
[15] Mr Naylor is an Arboricultural Scientist for Treescience Pty Ltd, an arboricultural
consultancy. He has 28 years’ experience in urban arboriculture. He produced two
reports. In his first report dated 12 April 2024, Mr Naylor relevantly stated:
(a) the subject tree predates the purchase of the adjacent properties. It has landscape
amenity value.
(b) It is clearly apparent that the Gardners have utilised established arboricultural
management principles which has ensured a viable and sustainable urban
landscape tree with consideration of a tree keeper’s responsibilities.
-- 4 of 10 --
5
(c) it is prudent and reasonable to state that the Gardners are more than urban
observers of the trees because they have administered a level of tree
maintenance works over a period of time.
[16] In his second report dated 26 April 2024, Mr Naylor advocates for the retention of
tree. He relevantly stated:
(a) the subject tree consists of two trunks in close proximity and therefore is
classified as a single tree.
(b) a Chinese Elm tree is an environmental woody weed species and declared
Category 3 Restricted Matter (Biosecurity Act 2014 (Qld)) in Queensland.
Under this Act sales and distribution is restricted.
(c) in his professional opinion the tree has reached maturity and has commenced
arresting its growing potential.
(d) he designed and implemented a plant health care program for the tree and
installed a Cobra tree bracing system for tree for the reasons outlined in the
Richards report.
(e) Mrs Andrews’ removal of woody anchorage tree roots “poses many
complexities with regards to long term tree retention”. The removal of said roots
“ha[s] exacerbated the subject tree’s risk potential via wood degradation,
reduced tree vitality in addition to the possible onset of insect pests and fungal
pathogens if not correctly managed…”
(f) the “canopy trajectory of the subject tree is somewhat elevated, providing no
residential yard restriction or foreseen impediments and therefore is not
classified as a nuisance with consideration of the adjoining neighbour’s
reasonable enjoyment of his or her land”.
(g) Mrs Andrews’ interference with the tree has “potentially compromised the
subject tree and useful life expectancy as a functioning landscape amenity tree”
and would “take years to remediate”.
The Hearing
[17] A hearing took place on 29 and 30 April 2024. Mr Richards and Mr Naylor gave
concurrent evidence in an arrangement colloquially referred to as the “hot tub”
method. Relevantly, they said:
(a) Mr Richards was shown exhibit 2, which is a series of photographs of the tree’s
trunk with a stringline running alongside it (the Gardners contend that the
stringline marks the true location of the common boundary). In the photographs,
a portion of the tree’s trunk appears to be situated directly below the stringline.
Mr Richards was asked what effect removing that portion of the tree would have
on its health. In response, he opined that taking such a step would “create
structural instability” and be a “death sentence for the tree”.
(b) Mr Naylor was also given exhibit 2. He said that removing the portion of the
tree under the stringline to soil level would have a significant effect on the tree’s
health, but it “might survive”. However, if its roots were removed below soil
level the “tree’s structural integrity would be impacted and it may die”.

(c) Mr Richards is not worried the tree is “immediately going to fall”. it has
responded well to interventions. Mr Naylor also stated that the tree had
responded well to his healthcare regime.
(d) Mr Naylor said that no pruning to the upper canopy of the tree should take place
for at least two to three years because its canopy had already been reduced by
20 percent.
(e) Mr Richards and Mr Naylor both agreed that the top section of any proposed
fence would need to be cut out because the tree’s trunk leans into Mrs Andrews
property.
[18] Mrs Andrews gave the following evidence, and made the following submissions at
the hearing:
(a) the tree has deposited sooty mould on her pool umbrellas which are only two
months old. The photographs of the umbrellas in her material were taken a week
prior to the hearing. The umbrellas which are furthest away from the tree have
no mould on them.
(b) she has installed a temporary fence because the existing fence has so many gaps
in it.
(c) overhanging branches from the tree presently extend six to seven metres across
her property. The tree currently shades approximately one third of her yard.
(d) a large quantity of leaves continues to fall in her pool notwithstanding the
pruning to the tree that in December 2022.
(e) scalloping the fence or constructing it with gaps would look ugly and is
incongruent with surrounding fences. It would be an “eyesore”.
(f) the Gardners have failed to provide the Tribunal with evidence that a fence can
be constructed if the tree remains in situ.
(g) the Gardners have taken no steps to prune the trees since January 2016.
(h) the monitoring regime suggested by the experts is more costly than removing
the trees in the first instance.
[19] At the hearing the Gardners gave the following evidence and made the following
submissions:
(a) they do not dispute the Trilogy survey but they take issue with the location of
the blue marker that Trilogy placed in the tree to indicate where it intersects
with the common boundary. Stringline tests that the Gardners conducted
returned different results to Trilogy. They posit that pruning may have caused
the tree to move after the Trilogy marker was installed.
(b) they do not dispute that the existing fence needs to be replaced or that the
existing retaining wall should be removed, rather both should be constructed in
such a way that it accommodates the tree.
(c) whilst they conceded that the tree causes some shading, they did not consider it
to be onerous.
-- 6 of 10 --

(d) they deny that sooty mould damaged the existing fence or is apt to damage any
future fence. They contend that the fence is degrading naturally as all timber
fences inevitably do.
Relevant law
[20] Under s 66 of the Act, the Tribunal may only make an order about a tree affecting the
neighbour’s land if it considers such an order is appropriate to:
(a) prevent serious injury to any person; or
(b) to remedy, restrain or prevent:
(i) serious damage to the neighbour’s land or any property on the neighbour’s
land; or
(ii) substantial, ongoing and unreasonable interference with the use and
enjoyment of the neighbour’s land.
[21] If future serious injury, serious damage or interference is contended, it must be likely
to occur within the next 12 months.1
[22] Notably, s 71 of the Act provides that the primary consideration (for QCAT) is the
safety of any person.
Findings
Is an order necessary to prevent serious injury to any person within 12 months?
[23] I am not persuaded that an order is necessary to prevent serious injury to any person
within the next 12 months. Mrs Andrews’ contentions that the deteriorating health of
the tree poses a risk of future tree failure and injury to her children are not supported
by the evidence of either assessor. Both assessors agree that the tree is responding
well to the plant healthcare program and is not in imminent danger of toppling.
Is an order necessary to remedy, restrain or prevent serious damage to the
neighbour’s land or property within 12 months?
[24] I do not consider that there is sufficient evidence before the Tribunal for me to
conclude that an order is necessary to remedy, restrain or prevent serious damage to
Ms Andrews’ land or property within the next 12 months. After excavation of Mrs
Andrews’ land and severe pruning of the tree occurred in December 2022, there are
no longer any tree roots that pose the risk of compromising the structures on her land.
Is an order necessary to remedy, restrain or prevent substantial, ongoing and
unreasonable interference with the use and enjoyment of the respondent’s land?
[25] During the hearing, much time was devoted to the issue of the accuracy, or otherwise,
of the blue marker that Trilogy placed on the tree. I find that the blue marker accurately
indicates where the tree intersects with common boundary. I do not place any credence
on the accuracy of the stringline method adopted by the Gardners. With all due respect
to the Gardners, they are not registered surveyors within the meaning of the Surveyors
Act 2003 (Qld) and are not qualified to determine property boundaries.
1 The Act, s 46(a)(ii).

[26] It is plain to me that the location of the tree on the common boundary precludes the
erection of a new dividing fence without scalloping or building it on either side of the
tree. I accept Mrs Andrews’ submissions that a fence constructed in such a fashion
would be ugly and incongruent with neighbouring fences. In my opinion, it is
fundamental to a person’s enjoyment of their land that they ought not be compelled
to live with a large tree projecting through their fence. Further, I am satisfied, after
viewing photographs provided by Mrs Andrews, that the tree’s roots are protruding
through the bottom of the palings of the existing fence. The damage that the roots
have caused to the fence is obvious.2 It is doubtful that any gardens could be planted,
let alone thrive, whilst the tree’s roots remain in situ.
[27] I find that Mrs Andrews’ inability to plant gardens on her land or erect an aesthetically
pleasing fence on the common boundary, amounts to a substantial, ongoing, and
unreasonable interference with her enjoyment of her land. Further, I consider that the
only means by which that interference can be sufficiently ameliorated is for the
Tribunal to order that the tree is removed. In this case, the construction of a fence and
gardens, and the retention of the tree, are simply incompatible objectives.
[28] There are further reasons the tree must be destroyed. Photographs from 2015, 2021,
2022 and 2023 appear to show a significant quantity of leaf litter from the tree
scattered on Mrs Andrews’ lawn, pool, paths, and garden furniture.3 Notably, the pool
photographs were taken in 2023. Clearly, significant pruning of the tree in December
2022 did not arrest its leaf drop. There appears to not be much of a difference between
the quantity of the leaf litter between the photographs of the yard taken in 2015 and
those taken in 2023. I infer therefore that future pruning is unlikely to meaningfully
alleviate leaf drop.
[29] Even if the inference I have drawn above is wrong, the evidence of both assessors was
that pruning of the tree’s canopy of Mrs Andrews’ land was not recommended until
two to three years had passed. It is patently unreasonable that Mrs Andrews must wait
so long for relief. I therefore find that the leaf litter substantially and unreasonably
interferes with Mrs Andrews’ enjoyment of her land because it unsightly and requires
frequent removal. The interference is ongoing insofar as it is repeated for several
months every year.
[30] There are photographs of black sooty mould on Mrs Andrews’ deck chairs and pool
umbrellas. Those photographs were taken after the tree was pruned in December 2022.
The umbrellas furthest away from the tree do not have mould on them. I infer therefore
that it is the tree that is causing the mould. The fact that Mrs Andrews’ deck chairs,
which are situated near the trees, are also covered in mould, strengthens the veracity
of that inference. I find that that the black sooty mould substantially and unreasonably
interferes with the applicant’s enjoyment of her land because it is unsightly and
requires her to replace her furniture, which is financially burdensome and
inconvenient.
[31] I am mindful that s 72 of the Act provides that a living tree should not be removed or
destroyed unless the issue relating to the tree cannot otherwise be satisfactorily
resolved. In this case, I am not satisfied that issues relating to the tree can be
2 Applicant’s written submissions, Appendix 4.
3 Ibid, Appendix 9.
-- 8 of 10 --
9
satisfactorily resolved. I have found that the construction of a fence and gardens, and
the retention of the tree, are simply incompatible objectives.
[32] Further, I am not satisfied that the two-to-three-year delay before the tree can be
pruned is reasonable. Even if pruning could occur earlier, I am not persuaded that it
will meaningfully ameliorate the deleterious impacts of the tree dropping leaves and
producing sooty mould.
[33] Section 73 of the Act requires the Tribunal to consider various general matters, my
findings in respect of which are set out below:
(a) the tree is located close to Mrs Andrews’ pool and the existing fence and has
the potential to adversely impact those structures.
(b) carrying out work on the tree requires no consent or authorisation under another
Act.
(c) the tree has no historical, cultural, social, or scientific value.
(d) the tree contributes positively to the natural landscape and the scenic value of
the land on which it is located.
(e) the tree makes no contribution to public amenity.
(f) the tree contributes positively to the amenity of the land on which it is located.
It provides shade, imparts a cooling effect and is aesthetically pleasing to look
at. However, I note that there is already a row of amenity trees that are larger on
the subject tree on the Gardners’ land that will provide shade and cooling. In my
view, that balances the loss of amenity caused by the removing the tree.
(g) the tree is a category 3 weed. There is a plethora of literature which depicts the
Chinese Elm as a destructive and undesirable tree.
[34] Where unreasonable interference with the use and enjoyment of a person’s land is
alleged, s 75 of the Act requires me to consider various matters. My findings on those
matters are set out below:
(a) I do not consider that there is anything other than the tree that has contributed
or is contributing to the interference.
(b) the Gardners have taken no steps to maintain the tree since pruning it in January
2016 despite knowing for years the adverse impact it was having on their
neighbours. I have little confidence they will adequately maintain the tree going
forward if it is retained.
(c) Mrs Andrews’ land is not particularly large and the tree looms over it.
(d) I consider that the detriment the tree causes Mrs Andrews outweigh arguments
favouring its retention, despite it existing prior to Mrs Andrews acquiring her
land.
[35] For completeness, I am satisfied of the requirements before an order may be made
stated at s 65 of the Act. Relevantly:
(a) I am satisfied that Mrs Andrews has made genuine and reasonable attempts to
resolve the dispute, even going to far as to pay for the full costs of removing the
tree and erecting a new fence.
-- 9 of 10 --
10
(b) concerning the issue of Mrs Andrews’ land being affected because branches
from the tree overhang the land, I am satisfied about the following:
(i) the tree’s branches extend to a point over Mrs Andrews’ land that is at
least 50cm from the common boundary; and
(ii) Mrs Andrews cannot properly resolve the dispute under part 4 of the Act.
(c) Mrs Andrews has given the Gardners a copy of the application for a tree dispute
in compliance with s 63 of the Act.
[36] For the reasons articulated above, I propose to make an order for the removal of the
tree. I see no reason why the Gardners, as the tree keeper, ought not bear the entire
costs of doing so. I also intend to award Mrs Andrews her costs for bringing the
application for a tree dispute.
[37] Mrs Andrews seeks orders from the Tribunal pertaining to the construction of a new
fence and a retaining wall. The tribunal has no jurisdiction to make such orders in a
proceeding for a tree dispute. However, I intend deliver a decision and reasons for
Q759-23, concerning the fence, in due course.
The Gardners’ application for compensation
[38] The Gardners have applied to the Tribunal for monetary compensation, or
alternatively costs, for the health care measures they took following the pruning and
removal of the tree’s roots that Mrs Andrews undertook in December 2022. In my
view, the Gardners are not entitled to such compensation. There is nothing in the Act
which empowers the Tribunal to make such an order for the benefit of a ‘tree keeper’.
Additionally, the costs that the Gardners incurred were not ‘costs of the proceeding’,
in the sense that they were not incurred to advance the Gardners’ position in the
proceeding. Rather, they were expenses incurred to preserve the tree before the
proceeding commenced.
