Dividing Fences Law in Australia: State by State Comparison

Every Australian state and territory has its own dividing fences Act. All eight follow the same basic shape, notice, a response period, then an application to a forum if agreement fails, but the forum, the response period and the cost-sharing default differ in ways worth checking before contacting a neighbour.

How a dividing fence dispute works, in every state

Every Australian dividing fences Act follows the same underlying structure. An owner who wants a fence built, replaced or repaired gives the adjoining owner written notice proposing the work and the split of cost. If the adjoining owner does not respond, or the owners cannot agree within the Act's response period, either owner can apply to the jurisdiction's forum (a court, a tribunal, or in Tasmania an arbitrator) for an order or award settling the dispute. The forum then decides matters such as the type of fence, its location and how the cost is shared. None of the eight Acts lets an owner build a fence and simply demand payment afterwards without having given notice first, though Western Australia works differently: section 13(1) is the Act’s general basis for cost recovery, letting an owner who has built a sufficient dividing fence claim half its value from the adjoining owner whether or not notice was given. Later subsections add a narrower mechanism for recovering from an owner who only later builds on or occupies the land.

Comparison table

New South Wales' concurrent jurisdiction is unusual

Most states send fencing disputes to a single forum. New South Wales is the exception: section 13 of the Dividing Fences Act 1991 gives the Local Court and the Civil and Administrative Tribunal (NCAT) concurrent jurisdiction, and a pending application can even be transferred from one to the other if it appears more appropriate to do so. No other Australian jurisdiction splits fencing jurisdiction this way. See dividing fences in New South Wales for how to use this in practice.

Not every forum is a court or a tribunal: Tasmania uses arbitration

Tasmania stands apart from every other Australian jurisdiction. Section 26 of the Boundary Fences Act 1908 (Tas) provides that a dispute between adjoining owners "shall... be referred to and decided by arbitration in accordance with the Commercial Arbitration Act 2011", not by a court or the state's civil tribunal, TASCAT. An owner who objects to a proposed fence has 21 days to signify that objection in writing under section 10, after which, absent agreement, the matter proceeds to arbitration under Part IV of the Act. See dividing fences in Tasmania for what that process actually involves.

Cost-sharing default: usually equal, with real exceptions

New South Wales, Victoria, Queensland and the Northern Territory all start from the same position: adjoining owners contribute equally to a fence built to the standard of a "sufficient dividing fence", and an owner who wants something more expensive pays the difference themselves. Western Australia works differently in practice: rather than a default split negotiated up front, section 13 lets an owner who has built a sufficient fence claim half its value from the adjoining owner after the fact. The Australian Capital Territory's ACAT can order a contribution, but section 10(3) caps that order at half the cost of a "basic fence" unless the Tribunal is satisfied a basic fence is impracticable or special circumstances justify more. Tasmania is the one state that does not state a fixed statutory default. South Australia does: section 12(6) presumes equal benefit absent proof to the contrary, and section 12(7) sets liability at one-half of the minimum cost of an adequate fence where the owners have not agreed where a cross-notice under section 6 does not resolve it, and a Tasmanian arbitrator awards a proportion under Part IV where the parties cannot agree one themselves.

Before you apply: put it in writing

Every jurisdiction's process starts with a written notice, not a phone call or a conversation over the fence line. Keeping a written record protects both an owner's ability to apply to the relevant forum later and their position if a dispute does end up there. None of the eight Acts gives a neighbour the right to start building on, or demolishing, a shared fence without first following the Act's notice process, and doing so can affect that owner's ability to later recover a contribution.

Frequently Asked Questions

Do I need my neighbour's agreement to build a dividing fence in Australia?

In every state and territory, the standard process starts with a written notice proposing the fence and inviting agreement. If the neighbour does not respond or the owners cannot agree within the applicable period, either owner can apply to that jurisdiction's forum, a court, tribunal, or in Tasmania an arbitrator, for a binding order or award.

Who pays for a dividing fence in Australia?

The starting position in New South Wales, Victoria, Queensland and the Northern Territory is that adjoining owners contribute equally to a fence built to a "sufficient" standard. Western Australia, South Australia, Tasmania and the ACT each use a different mechanism; see the linked state page for the one that applies to a specific dispute.

Which court or tribunal decides a fencing dispute in New South Wales?

Either the Local Court or the Civil and Administrative Tribunal (NCAT), under section 13 of the Dividing Fences Act 1991 (NSW), which gives the two concurrent jurisdiction. A pending matter can be transferred between them.

Is a fencing dispute in Tasmania decided by a court?

No. Under section 26 of the Boundary Fences Act 1908 (Tas), disputes are referred to arbitration under the Commercial Arbitration Act 2011, not to a court or to TASCAT.

How long do I have to respond to a fencing notice in Australia?

It varies by jurisdiction: 21 days in Western Australia and Tasmania, 30 days in Victoria, South Australia and the ACT, and 1 month in New South Wales, Queensland and the Northern Territory. See the comparison table above for the exact period and section reference.

Does the Northern Territory have a dividing fences law?

Yes. The Fences Act 1972 (NT) sets a default equal contribution, a 1-month response period, and lets either owner apply to the Northern Territory Civil and Administrative Tribunal (NTCAT) if agreement is not reached.

Can I be forced to pay for an expensive fence I did not want?

Generally, no. An owner who wants a fence built to a higher standard than a "sufficient dividing fence" is usually liable for the extra cost above that standard themselves, under the equivalent provision in each state's Act.
