Our expert says

"Inflation rose in the June quarter but it was in line with RBA's own forecasts heading off the need for another rate hike. At the same time inflation is still too high and the RBA still lacks confidence that it will sustainably head back to target so it's too early to expect a cut."

Surging home loan sizes across Australian states

Over the past decade, the average sizes of home loans in all states have shown significant increases. ACT takes the lead with over 100% increase, doubling the average home loan size. South Australia and Tasmania follow closely increasing around 90%, while Queensland increased around 80% in the size of home loans over the same period.

Growing preference for external lenders

In 2019, slightly more than half of refinancers, accounting for 52%, were external refinancers, indicating that they sought new loans from lenders other than their current one. Fast forward to 2023, the landscape has evolved significantly, with nearly three-quarters of all refinancers being external. In December 2025, 59% falling into the category of external refinancers. Demonstrating a growing trend of homeowners exploring new lending options outside their existing lenders, showcasing changing dynamics in the refinancing market.
