How Much Deposit Do You Need in Australia?

The standard minimum is 20% of the property price — any less and lenders will usually require Lenders Mortgage Insurance (LMI). However, programs like the First Home Guarantee let eligible buyers purchase with as little as 5% deposit, with the government covering the LMI gap.

Typical Deposit + Upfront Costs

20% deposit (no LMI): 20% + ~3–5% for stamp duty, legals, inspections.
10% deposit (with LMI): 10% + ~3–5% upfront + $8,000–$25,000 LMI.
5% deposit (via First Home Guarantee): 5% + ~3–5% upfront, LMI typically waived.
