These are the free property investment resources Australia investors actually need — the tools, calculators, and data sources I use when researching and managing my own investment properties. Everything listed here is free. Nothing is sponsored or affiliated — I’m not making money if you click any of these links.
I’ve organised them by what stage of the process they’re most useful for, so you can jump straight to what you need.
How to use these free Australian property investment tools
Research and due diligence
SQM Research — Vacancy Rates
Free vacancy rate data by suburb, updated monthly. This is one of the first things I check when assessing a location. A vacancy rate below 1% tells you rental demand is structurally strong. Above 3% and you need a very good reason to buy there. Use the free section — the paid data isn’t necessary for most investors.
Domain Research
Free suburb profiles, median price trends, and days on market data. Best used alongside SQM for a rounded picture of a suburb’s rental and sales market. The median price trend graphs are particularly useful for spotting suburbs that have run hard recently (be cautious) versus ones that have been flat (potentially more upside).
ABS Census Data
The Australian Bureau of Statistics Census has free demographic data on every suburb in Australia — renter ratios, income levels, household size, employment type. Useful for understanding who actually lives in the area you’re considering and whether the rental demand is structural or cyclical.
Finance calculators for property investment in Australia
MoneySmart Mortgage Calculator
ASIC’s free mortgage calculator. Straightforward, no sign-up, and trustworthy. I use it for quick repayment estimates when running initial numbers on a property. It also has a comparison rate calculator which is useful when looking at different loan products.
ATO Rental Property Expenses Calculator
The Australian Tax Office’s own tool for working out what you can claim on a rental property. Useful for a first-pass estimate of your tax deductions. Note that it doesn’t replace advice from a tax accountant — but it’s a good starting point for understanding what’s claimable before you sit down with one.
Understanding property law and tenancy rights
State Tenancy Authorities
Each Australian state has its own residential tenancy authority with free landlord guides, bond information, and tenancy agreement templates. Here are the main ones:
- Consumer Protection WA (Western Australia)
- NSW Fair Trading (New South Wales)
- Consumer Affairs Victoria (Victoria)
- Residential Tenancies Authority (Queensland)
Reading and learning
I don’t recommend most property investment books because they’re usually written by someone selling a course or a system. There are exceptions, and I’ve listed the best ones below. The principles transfer directly to property investment in Australia even if the books don’t mention property specifically — understanding behaviour and long time horizons matters far more than any individual tactic.
A few things worth reading:
- The Barefoot Investor — Scott Pape. Australian personal finance foundation. Good for getting your financial house in order before you invest.
- Thinking, Fast and Slow — Daniel Kahneman. Not about property, but essential for understanding why we make bad investment decisions emotionally and how to slow that process down.
- The Psychology of Money — Morgan Housel. Short, clear, and practical on how time and behaviour matter more than picking the right asset.
If there’s a free property investment resource you think should be on this list, get in touch via the About page. I also cover how to use many of these tools in the getting started guide — that’s a good next read if you’re at the research stage of buying your first investment property in Australia.
