First Home Buyer Guide Australia
Last updated: March 13, 2026
답부터 정리
Australian first-home buyers usually need to plan for more than the deposit. The real decision path includes borrowing power, stamp duty or concession exposure, LMI risk, grants, legal costs, and whether the remaining cash buffer is still safe after settlement.
Use this page as a practical first-home-buyer hub if you are trying to work out what to do first, how much cash you need, and which calculators to use before speaking to a broker.
Key Australian takeaways
- First-home-buyer support is state-based, so duty concessions and grants should be checked where you plan to buy.
- A bigger deposit is only one path. Guarantor support or an eligible support scheme may also change the cash required.
- Before speaking to a broker, you should already know your borrowing range, deposit path, and likely upfront costs.
Key costs and decisions
Your first-home-buyer budget usually turns on five linked decisions: how much deposit you can contribute, how much you can borrow, whether stamp duty concessions apply, whether LMI is triggered, and whether a grant or guarantee changes the cash you need on settlement day.
State-based differences
First-home-buyer support is not uniform across Australia. Stamp duty concessions, grant amounts, and property-value thresholds vary by state, so the right strategy in NSW may not be the same one for QLD, VIC, WA, SA, ACT, TAS, or NT.
Grants and concessions by state
Use these quick links as a state-aware planning layer. NSW, VIC, QLD, and WA have dedicated duty pages, while the Australia-wide calculator helps you compare SA, ACT, TAS, and NT without assuming east-coast rules apply everywhere.
SA / ACT / TAS / NT
Use the Australia-wide calculator to compare lighter state and territory scenarios before narrowing your target market.
SA / ACT / TAS / NTThree common support paths
Bigger deposit
A larger deposit can reduce LVR and LMI, but it may delay entry and still does not remove duty or legal costs.
Guarantor support
A guarantor structure can reduce upfront pressure for some buyers, but it changes risk allocation and should be understood before commitment.
Support scheme eligibility
A support scheme may lower deposit pressure for eligible buyers, but it does not replace the need to check full upfront costs and repayment safety.
What to do first
- Check borrowing power before you fall in love with a suburb or price range.
- Model 5%, 10%, and 20% deposit scenarios so you know your LVR and LMI risk.
- Estimate stamp duty and total upfront costs in your target state.
- Confirm whether first-home-buyer grants, guarantees, or concessions actually change the cash you need.
- Stress-test repayments before you request pre-approval or make an offer.
What to do before speaking to a broker
- Estimate your borrowing range before searching seriously
- Compare 5%, 10%, and 20% deposit scenarios
- Check likely state-based concession eligibility and price limits
- Include legal, inspection, settlement, and duty costs in your cash plan
- Stress-test repayments before offer stage
Deposit Benchmarks
- 5% deposit: faster entry, generally higher financing pressure
- 10% deposit: common middle-ground strategy
- 20% deposit: usually strongest risk and cost profile
Australian examples
Smaller deposit, faster entry
A first-home buyer trying to buy around $700,000 with a 5% or 10% deposit may enter the market sooner, but should expect tighter buffers, a higher LVR, and possible LMI unless scheme support applies.
Bigger deposit, lower risk
A buyer who waits until a 20% deposit is available may reduce LMI exposure and improve monthly cash flow resilience, but needs to weigh that against time out of the market and rising prices.
Common first-home-buyer mistakes
- Treating the deposit as the full cash requirement instead of budgeting for duty, legal fees, inspections, and LMI.
- Assuming a state concession or grant applies without checking price caps and eligibility details.
- Relying on an online repayment estimate without comparing it to real borrowing-power limits.
- Using every dollar for the deposit and leaving no settlement or post-purchase buffer.
FAQ
How much deposit does a first home buyer need in Australia? There is no single national rule. Some buyers target 20% to avoid LMI, while others enter with less and accept LMI or rely on support schemes. The right answer depends on cash buffer, borrowing power, and state-based costs.
Do first home buyers pay stamp duty? Sometimes yes, sometimes less, and sometimes none. It depends on your state, property value, and whether you qualify for a first-home-buyer concession or exemption.
What grants are available by state? Grant and concession settings vary across Australia. You should check the relevant state page and official criteria because amounts, price caps, and eligibility can change.
Can first home buyers avoid LMI? Some can, either by reaching a lower LVR, using guarantor support, or qualifying for a support scheme. But many first-home buyers still need to compare scenarios with and without LMI.
What should I do before speaking to a broker? Know your deposit range, estimate your borrowing power, check likely upfront costs in your state, and stress-test repayments so the broker conversation starts from realistic numbers.
