Your guide to Australia’s rental crisis and tenant rights

Finding an affordable rental property in Australia right now can feel like looking for a needle in a haystack—and when you do find it, the price tag is often eye-watering.

If you are looking at your budget and wondering exactly why your rent keeps climbing, you are not alone. There is a range of pressure points pushing prices up across the country, from interest rate hikes to a critical undersupply of housing.

At the core, there’s just not enough homes to go around

The massive undersupply of homes in Australia is at the core of the rental price hikes, because if there was plenty of properties to pick from, and a landlord pushed their prices up too high, they’d find themselves without a tenant.

But there just aren’t enough homes – to buy or rent – to go around.

What this has resulted in, is critically low vacancy rates across the country (just to note, anything under about 2.5% is tight and Sydney is the highest at 1.8%).

How often can landlords increase rent?

The good news for tenants is that there has been plenty of rule-tightening recently in your favour. In almost every state and territory, rent can only be increased once a year. The only exception is the Northern Territory, where it is permitted twice a year.

The notice your landlord must give you is typically two months (60 days), though Victoria requires 90 days and the Northern Territory requires 30 days.

Interestingly, if a landlord raises the rent and the tenant subsequently moves out, the one-year timer typically resets for the next tenant. However, jurisdictions like Queensland have closed this loophole: the rule stays with the property. If a Queensland tenant moves out today, the landlord still cannot lift the rent for a new tenant until the following year.

How much can rent go up by?

Unfortunately, there are no specific maximum dollar caps on rent increases in most of Australia, except in the ACT. In the ACT, increases are typically capped at 10% more than the current inflation in rents, unless the tenant agrees in writing or the landlord gets the green light from the tribunal.

How to fight a rent increase

If your landlord hits you with a rent increase and you believe it is unreasonable, you have the right to dispute it. Your first step should always be direct negotiation.

Here is how to build your case and use your "bargaining chips":

• Do your research: Check how your new rent stacks up against similar properties in your area. Tools like NSW’s online rent checker can give you a quick ballpark figure. You can also search real estate listings on websites like Realestate.com.au or Domain for comparable local properties.
• Compare to inflation: Look at how much your rent is going up in percentage terms and compare it to the Consumer Price Index (CPI). Across the country, CPI for rents is currently sitting at 3.7%.
• Highlight your value: Remind the landlord or agent that you are a fabulous tenant who takes care of the property and pays rent on time. A tenant change is costly for a landlord—they face vacancy gaps, advertising fees, and lease preparation costs.
• Know your budget: Work out exactly what you can realistically afford to pay. If you want to land in the middle, start your counter-offer slightly lower (but not completely offensive) and negotiate up to that halfway point.
• Have the conversation early: Start the discussion as soon as you receive the notice. A friendly phone call or in-person chat with the agent or landlord can often be much more effective than a stern, legalistic email that gets their back up immediately.
• Get it in writing: Once you agree on a figure, ensure everything is formally documented via email or an updated tenancy agreement.

If negotiations stall, you can escalate the issue to your state-based tribunal (or request a formal rent assessment in Victoria). Keep in mind there are strict deadlines—for example, in NSW, you have just 30 days after receiving the rent increase notification to raise a formal dispute.

What to do if you can't afford your rent

If you receive a rent increase notice and simply cannot afford it, time is of the essence. While you legally have the notice period (typically 2 months) to figure out your next steps, missing a payment after that period means a landlord can take eviction action in a matter of weeks.

1. Check for government financial support

• Commonwealth Rent Assistance: Check if you are eligible for Rent Assistance through Services Australia. To qualify, you must be receiving a base government payment (such as the Age Pension, Austudy, a Carer Payment, or Family Tax Benefit A at more than the base rate) and be paying over a certain amount of rent each week.
• State schemes: Check with your local state government, as many offer rental relief grants or bond loan schemes for residents facing hardship.

2. Contact free support services

If you don't know where to turn, professional help is available. The National Debt Helpline (1800 007 007) is a free, Australia-wide service that can connect you with local financial counsellors.

Should you move or transition to a rolling lease?

In each state and territory you can move on to a rolling lease but there are nuances between the jurisdictions so check the rules that apply to you before you do.

In NSW, for example, you can move on to rolling lease and in that you typically only need to provide 21 days notice.

Another fixed term lease can give you certainty, particularly where there are still no grounds evictions but if you need to leave early and have to break the lease it could end up being costly. 

Which one you decide – a rolling lease or another fixed term lease will come down to individual choice, and, to some extent, the rules in your state and territory. 

So just understand what the rules are in your area and check whether you, in fact, have to enter another fixed term contract.

Taking a dispute to a tribunal: what to expect

If you choose to challenge a rent increase formally, the process involves filling out a form detailing your case and providing evidence (like local market listings and your communication history) showing why the increase is unfair. This is why getting everything in writing during negotiations is critical.

While the process can be time-consuming, it is not like a formal court of law. You can represent yourself, and the setting is generally less formal. However, be aware of filing fees; while they can be under $20 in some areas, they vary by state and can run up to nearly $400 in extreme cases (such as in Queensland).

Also be aware there are set timeframes for raising an issue and they’re often much shorter than you think. 

For example, in NSW, you have just 30 days after you’ve received the rent increase notification to raise a dispute.
