What Is the Average Mortgage in Australia?

Buying a home is one of the biggest financial steps most Australians will ever take — and understanding the average mortgage size can help you plan better, set realistic expectations, and budget for your property journey.

Let’s take a closer look at how much Australians are borrowing, the factors that influence loan sizes, and what you can do to make smarter home loan decisions.

1. The Current Average Mortgage Size

According to recent data from the Australian Bureau of Statistics (ABS), the average new mortgage in Australia sits around $615,000 to $630,000, depending on the state or territory.

Here’s a quick breakdown:

  • New South Wales: around $750,000+

  • Victoria: around $620,000

  • Queensland: around $550,000

  • Western Australia: around $500,000

  • South Australia, Tasmania, NT: $400,000–$500,000 range

Of course, these figures fluctuate with market conditions, interest rate changes, and housing demand.

2. Why the Average Mortgage Keeps Changing

Several factors affect how much Australians borrow for their homes:

  • Rising property prices: As home values increase, loan sizes naturally rise to match.

  • Interest rate shifts: Higher rates can reduce borrowing power, while lower rates can encourage larger loans.

  • Income growth: Changes in wages and employment levels influence affordability.

  • Government incentives: Grants and first-home-buyer schemes often impact how much people borrow.

In short, the average mortgage tells part of the story — but your individual borrowing power depends on personal financial factors.

3. How Much Can You Afford to Borrow?

Every borrower’s situation is unique. Lenders assess your:

  • Income and employment stability

  • Existing debts and expenses

  • Credit score and repayment history

  • Deposit amount (usually 10–20%)

If you’re planning to buy soon, using a home loan calculator or getting pre-approval can help you understand what you can comfortably afford.

4. The Importance of Comparing Lenders

The average mortgage amount might be a national benchmark, but your best loan depends on the lender’s rates, flexibility, and features.

5. Managing Your Mortgage Smarter

Even if you’ve already taken out a loan, you can still optimise it. Consider:

  • Refinancing to get a lower rate or reduce your term.

  • Using an offset account to save on interest.

  • Making extra repayments when possible.

  • Exploring green or clean-energy loan options for renovations or upgrades.

Small changes to how you manage your mortgage can make a huge difference over time.
