Adverse Possession in Australia: State by State Comparison

Adverse possession lets a long-term occupier apply to become the registered owner of land, but the required period is not the same across Australia, and claiming land owned by a government body is barred or heavily restricted in every state examined.

Information last verified on 21 July 2026 against the primary legislation and, where noted, the relevant government agency page. This page presents general legal information, not legal advice.

Jurisdiction scope: This page covers adverse possession law in New South Wales, Victoria, Queensland, Western Australia, South Australia and Tasmania, verified 21 July 2026 against each state's Limitation Act (or equivalent) and, for New South Wales, the Crown Land Management Act 2016. The Australian Capital Territory and the Northern Territory have no adverse possession regime against registered land at all: the Land Title Act 2000 (NT) section 198 provides that no length of possession creates title or bars the registered owner, and in the ACT the Limitation Act 1985 section 5 excludes actions to recover land while the Land Titles Act 1925 sections 69 and 152 bar any title arising from possession. Each state has its own page covering the registry application, exclusions and fees: New South Wales, Victoria, Queensland, Western Australia, South Australia, Tasmania, and the two territories where it does not apply, the Northern Territory and the ACT.

What adverse possession actually requires

Adverse possession is a common law doctrine, given effect in each state by a Limitation Act, under which a person who has been in exclusive, open, uninterrupted possession of land as if they were the owner, without the true owner's permission, for a set number of years, can apply to have that possession recognised and, in most states, to be registered as the new owner. Courts look for conduct consistent with ownership: exclusive use that excludes the true owner and the rest of the world, maintained continuously for the entire statutory period. Casual or permitted use, and use that stops and starts, generally will not qualify. Every state examined below sets its own period and its own process, and several set out express exclusions for government-owned land.

The periods, state by state

The Australian Capital Territory and the Northern Territory are deliberately left off this table because neither has a period to state: the doctrine does not operate against registered land in either territory (Land Title Act 2000 (NT) s 198; Limitation Act 1985 (ACT) s 5 with Land Titles Act 1925 (ACT) ss 69 and 152). See the Northern Territory and ACT pages for what applies instead.

South Australia and Victoria: the fifteen year outliers

Most Australian readers assume a flat twelve year period, and in most states that assumption is correct. It is wrong in South Australia and Victoria. Section 4 of South Australia's Limitation of Actions Act 1936 provides that no action to recover land may be brought "but within fifteen years next after the time when the right to make that entry or distress or to bring that action first accrued." Victoria's Limitation of Actions Act 1958, section 8, uses almost identical wording: no action may be brought "after the expiration of fifteen years from the date on which the right of action accrued." Both provisions read, on their face, as ordinary limitation periods rather than doctrine-specific rules, which is part of why the shorter, more commonly cited twelve year figure gets applied to them in error.

Torrens (registered) land and the application process

Most Australian land is registered under the Torrens title system, and each state builds a separate application mechanism onto its general limitation period to convert qualifying possession into registered ownership. In New South Wales, Part 6A of the Real Property Act 1900 lets a possessor apply to the Registrar-General for a possessory title once the general limitation period has run; section 45C makes clear that no title adverse to a registered proprietor arises merely by the passage of time under the general limitation statute unless this Part's process is used. Victoria's mechanism sits in the Transfer of Land Act 1958: section 60 lets a person claiming title by possession apply to the Registrar for a vesting order, supported by a licensed surveyor's plan, with public notice and a minimum 30 day notice period posted on the land itself before the order can be made. South Australia takes a different default position: under the Real Property Act 1886, section 251 excludes adverse possession against a registered Torrens proprietor except as provided in Part 7A, and section 80A within that Part is the application mechanism, meaning the general limitation period alone does not, by itself, defeat a Torrens title in South Australia.

Government-owned land: barred or heavily restricted everywhere examined

The single most important limit on adverse possession in Australia is that it does not readily apply to land owned by government. New South Wales states this in the plainest possible terms. Section 13.1 of the Crown Land Management Act 2016 provides that title based on adverse possession "cannot be claimed or established against the Crown" for land that has been reserved as a road, reserved or dedicated for a public purpose, or otherwise remains Crown land, and the same bar extends to land held on trust for a public purpose. Western Australia achieves a similar practical result through its general limitation statute rather than a standalone Crown land Act: section 19(2) of the Limitation Act 2005 provides that an action to recover land may be brought by the Crown, or a person claiming through the Crown, "at any time" where the Crown's own cause of action is involved, meaning no limitation period runs against the Crown in the way it runs against a private owner. Every other state examined carves out similar protection for Crown, council or statutory-authority land in its own Act. The practical result is the same across the board: a person occupying land owned by a council, a state agency, or the Crown should not assume the same twelve or fifteen year clock that applies against a private neighbour applies against government land, because in most cases it simply does not.

What most readers are actually asking about: fence lines, not adverse possession

A large share of interest in adverse possession comes from a much narrower, more common problem: a dividing fence that turns out to sit slightly over the true boundary line, sometimes by a matter of centimetres, sometimes by a metre or more, often after decades without anyone noticing. That is a boundary and survey question, resolved by a licensed surveyor confirming the true boundary and, if needed, a negotiated adjustment or a formal boundary realignment process, not an adverse possession claim. Adverse possession requires the occupier to have used the land exclusively, as if they owned it, for the entire statutory period, which is a materially higher bar than an encroaching fence built without anyone intending to claim the neighbour's land. Readers dealing with a fence-line discrepancy are better served starting with a survey and, if needed, the state's dividing fences legislation, not by researching adverse possession.

What this page does not tell a reader to do

Nothing on this page should be read as advice that occupying a neighbour's land, or land belonging to a government body, for a period of years will result in acquiring it. The doctrine has real, technical requirements around the character and continuity of possession, and the outcome in any individual case depends on facts a written guide cannot assess. A reader who believes they may have an adverse possession claim, or who is concerned that a neighbour may have one against them, should engage a licensed surveyor to confirm the boundary and a legal practitioner admitted in the relevant state to advise on the specific facts.

Frequently Asked Questions

How many years of possession does adverse possession require in Australia?

It depends on the state. New South Wales, Queensland, Western Australia and Tasmania require twelve years against a private owner (Tasmania extends this to thirty years where the Crown is the party sued). South Australia and Victoria both require fifteen years. The Australian Capital Territory and Northern Territory periods are not stated on this page because they have not been independently verified.

Can I adversely possess land owned by the government in Australia?

Generally no. New South Wales expressly bars adverse possession claims against Crown land reserved or dedicated for a public purpose under section 13.1 of the Crown Land Management Act 2016. Western Australia achieves a similar result by letting the Crown bring a recovery action at any time under section 19(2) of the Limitation Act 2005. Similar restrictions on government-owned land exist in the other states examined.

If my neighbour's fence is on my land, can I claim adverse possession?

Usually this is a boundary and survey question, not an adverse possession claim. Adverse possession requires exclusive possession of the land as if you owned it for the full statutory period, which is a higher bar than an encroaching fence built without any intention to claim the land. A licensed surveyor can confirm the true boundary.

Does adverse possession automatically make me the legal owner after the time period passes?

No. In most states you must still make a formal application, such as under Part 6A of the Real Property Act 1900 (NSW) or section 60 of the Transfer of Land Act 1958 (Vic), including notice to interested parties and, in some states, a licensed surveyor's plan, before a possessory title can be granted.

Is South Australia's adverse possession period really fifteen years?

Yes. Section 4 of the Limitation of Actions Act 1936 (SA) states that no action to recover land may be brought "but within fifteen years" of when the right first accrued. This is longer than the twelve year period commonly assumed for Australian states generally.

Does Victoria's Torrens registration system stop someone claiming land by possession?

No, but it does impose a formal process. Section 60 of the Transfer of Land Act 1958 (Vic) requires a person claiming title by possession to apply to the Registrar with a licensed surveyor's plan, and requires public notice of at least 30 days before an order vesting the land can be made.
