What is the Average Mortgage Size by Age in Australia?

The average mortgage size in Australia varies significantly by age group, reflecting different stages of the property ownership journey. Younger Australians taking out their first home loan typically borrow less than older Australians who may be upsizing or refinancing established properties.

According to data from the Australian Bureau of Statistics Lending Indicators and APRA quarterly statistics, the average new loan commitment in Australia has grown substantially over the past decade, driven by rising property values in capital cities including Sydney, Melbourne, Brisbane and Perth.

Understanding how your mortgage compares to others in your age group helps you assess whether your borrowing level is typical for your demographic.
