Boundary fence rules: heights, cost sharing, front fences

Boundary fence rules in New South Wales, Victoria and Queensland come from two separate sets of rules in each state. A dividing-fences Act covers who pays for the fence between two properties, while the state's planning or building rules cover how high a fence can be and whether it needs separate approval¹. In all three states, the relevant Act treats a hedge and a gate as a fence, but not a retaining wall or a wall of a house or garage.

Cost sharing under each Act is based on whether the fence is considered a sufficient dividing fence. New South Wales and Victoria do not set a fixed height for this standard. Instead, the relevant court or tribunal considers factors including the existing fence, what the land is used for, privacy, the kind of fence usual in the area and any council policy or planning rules¹².

Queensland sets a default height range. Between two parcels of residential land a dividing fence is generally considered sufficient if it is between 0.5 m and 1.8 m high and is mainly made from an approved material. These range from timber palings and chain wire to bricks, concrete blocks and a hedge³. The height range is a default rather than a cap, because the same section also counts a fence as sufficient where the adjoining owners agree that it is or the Queensland Civil and Administrative Tribunal decides it is sufficient.

A fencing notice is the written proposal sent by one owner to the adjoining owner before fencing work begins. In all three states, a notice is generally required before an owner can recover a contribution towards non-urgent fencing work.

In New South Wales the notice must specify the boundary line, the type of fencing work and the estimated cost, and it may propose a cost split other than equal shares¹.

Victoria requires more information, including the date, the notifying owner's contact details, the boundary line, the type of works and fence, the contractor, the estimated cost and how it was calculated, the proposed cost split, the amount sought and information about dispute-resolution services².

Queensland's notice must be in the approved form, state the estimated cost including labour and materials, and be accompanied by at least one written quotation³.

Each state also sets a time for the adjoining owner to respond. In New South Wales, if the owners have not agreed within one month of the notice, either may apply to the Local Court or the NSW Civil and Administrative Tribunal (NCAT) for an order. The Act also provides for Community Justice Centre mediation¹.

In Victoria the neighbour has 30 days to respond. If there is no response within that period, the notifying owner may begin the work. If there is a response but no agreement, either owner can take the dispute to the Magistrates' Court².

In Queensland, no agreement within one month lets either owner apply to the Queensland Civil and Administrative Tribunal (QCAT) within two months of the notice, and the Queensland Government states that the tribunal handles fence disputes valued up to and including $25,000³⁵.

A side or rear fence generally does not need separate approval up to 1.8 m in New South Wales and 2 m in Victoria and Queensland, although each state applies its own conditions and exceptions.

In New South Wales a fence in the residential zones R1 to R4 or the village zone can qualify as exempt development if it is no higher than 1.8 m above the existing ground level. Masonry is limited to 1.2 m⁶.

This exemption does not apply in some circumstances, including a lot with a heritage item, some road boundaries in a heritage conservation area, a flood control lot or a foreshore area. Fences that fall outside the exemption are instead covered by the relevant council planning rules⁶.

In Victoria, a fence of no more than 2 m, other than a pool barrier, is exempt from a building permit. Height is measured from the natural ground level at the base of the fence to its top⁷.

A fence over 2 m needs a permit and is also subject to setback rules. Up to 3.6 m high, it must generally be at least 1 m from a side or rear boundary, with larger setbacks applying to taller fences unless council approval is given⁷.

In Queensland a fence generally does not need building approval if it is no higher than 2 m above the natural ground surface and is not a regulated pool barrier⁸.

A retaining wall under a fence is treated separately. A retaining wall can qualify for the no-approval pathway only where it meets its own limits, including a retained height of no more than 1 m and being at least 1.5 m from a building. A fence built on top of a retaining wall therefore has to meet the rules applying to both structures⁸.

Pool barriers are excluded from these general fence-height rules in all three states⁶.

Estate design guidelines set side and rear fence heights at 1.8 m across all nine estates reviewed that include a fencing rule. The documents cover eight estates in Queensland and one in Victoria as at July 2026.

Three of the nine, Flagstone, Harmony and Village Green, require a 1.8 m height rather than setting it as a maximum¹¹. Most also specify the material and even the colour, from painted timber palings at Village Green to a specified metal profile and colour at SkyRidge¹².

Alamora's registered memorandum of common provisions caps fences at 1.8 m while its design guidelines state 1.85 m¹³. The registered document sets the lower limit and is recorded on the title¹⁴.

Front fences vary more between estates. Six of the nine cap the solid part of a front fence at 1.2 m and allow more height only where the upper section is partly transparent. Alamora prohibits a front fence under its registered memorandum, and Harmony encourages one at 1.5 m to 1.8 m¹¹¹⁴. SkyRidge treats a front fence as optional and caps any required safety rail on a sloping frontage at 1.2 m¹⁵.

The fence rules for a block are recorded in several places: the state's dividing-fences Act covers cost sharing, the state's planning or building rules and the local council's planning scheme cover fence height and approvals, and, on an estate, the developer's design guidelines and the lot's title can add further requirements.

A memorandum of common provisions such as Alamora's is registered on the title, so its no-front-fence restriction applies to the land¹⁴. In Queensland, the tribunal can also consider any fencing requirement in a development approval for either lot³.

The position of the boundary line also affects who owns the fence. The Queensland Government states that a fence built on the common boundary is owned equally by the adjoining neighbours, while a fence built on one neighbour's land is owned by that neighbour even if the other helped pay for it. In New South Wales and Victoria, the reasonable cost of a surveyor can be shared equally where the owners cannot agree on the boundary line⁵.

BuildStreet's beyond-the-build checklist records fencing alongside other items that may sit outside a builder's base price, including driveways, landscaping, blinds and letterboxes. The fencing entry records which boundaries require fencing, the estate's specified style and height, and the relevant state cost-sharing rule. It does not determine whether a particular fence complies with those rules.
