Residential tenancies are state and territory legislation. That single constitutional fact means Australia does not have a rental market  it has eight, each with its own Act, its own regulator, its own dispute forum and its own reform timetable.

For most of the last decade those eight were drifting in roughly the same direction. Between 2022 and 2026 they stopped converging and started separating.

Four jurisdictions have abolished broad no-grounds termination: NSW, Victoria, South Australia and the ACT. Queensland abolished it for periodic tenancies but retains an end-of-fixed-term ground. Tasmania requires prescribed grounds for periodic tenancies but retains a fixed-term expiry ground. Western Australia and the Northern Territory retain broader no-grounds routes. The ACT is the only jurisdiction with a statutory formula limiting the amount of a rent increase, while the others primarily regulate frequency and notice. Bond ceilings range from a flat four weeks to six weeks above a threshold, and one jurisdiction has no central bond authority at all.

The practical consequence for anyone managing across borders is that the same tenancy event produces different obligations depending on which side of a line the property sits.

This guide compares the eight as they stand in September 2026. It is a map rather than a manual, and the detail in each jurisdiction goes well beyond what any comparison can carry.

1. Eight Acts, Eight Regulatory and Dispute Systems

Western Australia and Tasmania route possession through the Magistrates Court rather than a tribunal, while the other jurisdictions use specialist or administrative tribunals. Several jurisdictions also interpose an administrative determination step before any hearing, so a dispute can resolve without reaching a forum at all.

2. Ending a Tenancy: The Deepest Divergence

Three distinctions inside that table are easy to miss.

1. Queensland and Tasmania sit between the two camps, for different reasons. Queensland requires an approved reason for periodic tenancies but retains "end of a fixed term agreement" as a ground in its own right, on two months' notice. Tasmania has no free-standing no-grounds power, but s42(1)(d) provides a fixed-term expiry ground a notice may be given where the agreement is due to expire within 60 days that can operate like no-grounds termination at the end of a fixed term. Both look like grounds-based regimes on paper while functioning differently at expiry.

2. Notice periods bear no relation to each other. Queensland's non-breach grounds mostly run two months. South Australia splits into 60 days for possession-required grounds and 90 for other prescribed grounds. Victoria runs 90 days for most non-breach grounds, and its reform programme continues, with further changes commencing through 2026 and 2027. The ACT reaches 26 weeks for most no-fault grounds, with 8 weeks where the owner or family is moving in.

3. Evidence increasingly attaches to the notice itself. In several jurisdictions, particular termination grounds require supporting evidence to accompany the notice, and failure to provide it can invalidate the notice rather than merely weaken the case later. Tasmania is the clearest example: s43(3A) makes a notice on the sale or transfer ground of no effect unless proof of the agreement to sell is served with it. Victoria, South Australia and the ACT each impose comparable requirements on specified grounds.

3. Rent Increases

Two jurisdictions are genuine outliers.

1. The ACT is the only one that caps the amount. An increase is presumed excessive if it exceeds the prescribed amount, generally 110% of the change in the Canberra rents CPI since the relevant starting point. Going above that requires the tenant's written agreement or prior ACAT approval, and the burden sits with the lessor to show the increase is not excessive.

2. The Northern Territory permits increases twice as often as anywhere else, on the shortest notice in the country: every six months, with 30 days' written notice, and only where the agreement specifies the right and the amount or method of calculation.

Queensland's rule attaches to the property rather than the tenancy. A new tenant, a new agent or a new owner does not reset the twelve months, which defeats any system storing rent history against a tenancy record that closes at turnover. The RTA's rental law changes page tracks this alongside Queensland's other staged reforms.

4. Bonds

Three points stand out.

South Australia is the only jurisdiction where the lodgement deadline depends on whether you are a landlord or a registered agent. Tasmania has tenants pay the Rental Deposit Authority directly through MyBond, bypassing the landlord entirely.

The Northern Territory does not operate a central bond lodgement system. Under s29 of its Act, a private landlord holds the security deposit in trust and must pay it into an account established under s50 of the Agents Licensing Act or an account at a bank, building society, credit union or Territory statutory corporation. An agent holds it in a designated trust account. A landlord who leaves the Territory for more than 14 days must transfer the deposit to an agent or an approved person and tell the tenant. Failing to hold the deposit correctly carries a maximum penalty of 20 penalty units. Pet bonds are not permitted.

Portable bonds have also arrived unevenly. Victoria launched its Portable Rental Bond Scheme on 1 July 2026 with a $25 fee, and NSW began a staged Smart Rental Bonds rollout on 10 August 2026.

5. Pets

Tasmania's regime is the newest, commencing on 20 March 2026 under the Residential Tenancy Amendment (Pets) Act 2025. Tenants request consent for each pet on an approved CBOS form, and a landlord must not unreasonably refuse. Exempt animals, including assistance animals, need no consent, and strata by-laws continue to override the scheme.

In most jurisdictions, silence results in approval. The mechanism differs: some treat the request as approved automatically once the window passes, while others require the landlord to take a specific step usually a tribunal application to challenge it inside the period. Victoria, Tasmania, the ACT and the Northern Territory sit at that second end, where refusing is not simply a decision the owner makes but requires the prescribed tribunal process.

Pet bonds diverge too. Queensland expressly excludes both a rent increase and a pet bond as conditions of consent, and the NT does not permit pet bonds at all. Western Australia retains one, raised to $350 on 28 March 2026.

6. Trust Account Audits

For agencies this is the most under-appreciated table in the guide, because no two deadlines align and none of them appear in a generic compliance calendar.

Four different logics operate here. Most jurisdictions work from a financial year. WA uses the calendar year. Queensland's audit period is tied to the agency rather than a shared date, so two agencies in the same street can have different deadlines. South Australia ties it to your registration cycle and, uniquely, punishes non-lodgement with cancellation of registration rather than a fine.

An agency operating in three jurisdictions has three unrelated audit deadlines, at least one of which cannot be looked up in any industry guide. That is why reconciliation-grade reporting on client money has to be continuous rather than assembled ahead of a known date.

7. What Breaks When You Assume

Working across jurisdictions, these are the assumptions that cause real failures:

• That "Australian rental law" exists. Most content published as national is single-state. It is not approximately right elsewhere; it describes a different Act.

• That abolishing no-grounds means the same thing everywhere. Queensland and Tasmania both retain a functional route at fixed-term expiry despite requiring grounds.

• That the rent clock belongs to the tenancy. In Queensland it belongs to the property and survives tenant, agent and owner changes.

• That notice periods are a lookup. SA routes by ground and tenancy type into three different forms. The ACT spans 8 to 26 weeks depending on reason.

• That evidence is for the hearing. On specified grounds in several jurisdictions, evidence attaches to the notice, and its absence can invalidate the notice itself.

• That a bond ceiling is a fixed number. WA and SA both use rent thresholds a property can cross at its next increase.

• That someone else is holding the bond. In the NT, you are, and doing it wrong is an offence.

• That silence is safe. In most jurisdictions a pet request is approved if you let the window pass, and in Victoria, Tasmania, the ACT and the NT the refusal route runs through a tribunal rather than a letter.

Underneath all of it, condition reports, repair records and termination evidence carry the weight in every forum, which is why they belong in a structured work order and documentation workflow rather than in an email trail.

Conclusion

The eight jurisdictions are further apart in 2026 than at any point in the last decade, and the direction of travel is not uniform. Victoria and NSW moved hardest on security of tenure. The ACT went furthest on rent, capping the amount rather than just the frequency. Western Australia expanded tenants' rights inside a tenancy while leaving no-grounds termination untouched. Queensland attached its rent clock to the property. South Australia rebuilt termination into three separate routes. Tasmania handed pet refusals to a tribunal in March 2026. The Northern Territory kept a bond system nobody else runs.

For operators, the strategic conclusion is the same one that applies across the UK: the unit of compliance is the jurisdiction, not the country. Eight Acts, eight regulators, several dispute-forum models, and audit deadlines that follow four different logics.

Australian rental law can be understood. It cannot be generalised.

Frequently Asked Questions

1. Which Australian jurisdictions have abolished no-grounds termination?
New South Wales, Victoria, South Australia and the ACT have abolished broad no-grounds termination. Queensland requires grounds for periodic tenancies but retains an end-of-fixed-term ground. Tasmania requires prescribed grounds but has a fixed-term expiry ground under s42(1)(d). Western Australia and the Northern Territory retain broader no-grounds routes.

2. How often can rent be increased in Australia?
Once every 12 months in every jurisdiction except the Northern Territory, where it is once every six months. Queensland's 12-month period attaches to the property rather than the tenancy.

3. Does any Australian jurisdiction cap the amount of a rent increase?
Only the ACT. An increase above the prescribed amount, generally 110% of the change in the Canberra rents CPI, is presumed excessive and requires the tenant's written agreement or ACAT approval.

4. What is the longest rent increase notice period?
Victoria, at 90 days. The ACT requires 8 weeks. Most other jurisdictions require 60 days, and the Northern Territory 30.

5. Are rental bonds held by the government everywhere?
No. Seven jurisdictions use a central authority. The Northern Territory is the exception: the landlord or agent holds the deposit in trust in a compliant account under s29 of the Residential Tenancies Act 1999.

Important Notice

This article compares eight separate legal jurisdictions and is necessarily a summary. Residential tenancy law in Australia is state and territory legislation, and the detailed position in each differs beyond what a comparison can capture. Do not rely on this article for any specific action in any jurisdiction check the relevant state or territory guidance, and take advice qualified in that jurisdiction.

Information was checked against NSW Fair Trading, Consumer Affairs Victoria, the Queensland Residential Tenancies Authority and Office of Fair Trading, Consumer Protection WA, South Australian Consumer and Business Services, Tasmanian CBOS, TASCAT and the Residential Tenancy Act 1997 (Tas), ACT Government guidance, ACAT and the Residential Tenancies Act 1997 (ACT), and NT Consumer Affairs and the Residential Tenancies Act 1999 (NT), available as at 1 September 2026. Several jurisdictions are mid-reform: further Victorian changes commence on 13 October 2026 and 1 March 2027, and Western Australia has announced a further phase not yet in force. Notice periods, prescribed forms, thresholds, penalties and audit deadlines change frequently and vary within jurisdictions by tenancy type.
