On Wednesday, the Australian Bureau of Statistics (ABS) released housing finance data for Q4 2024. It revealed that the average Australian home loan has jumped to an all-time high of $666,000, up $25,000 over the quarter.

The average home loan in New South Wales also hit $800,000 for the first time.

The surge in average loan sizes is behind the inexorable growth in Australian home prices.

Australian housing affordability is severely stretched, evidenced by a record gap between borrowing capacity and median home prices.

As a result, the housing market requires three key things to continue appreciating.

  1. Interest rates need to fall to improve borrowing capacity.
  2. Incomes need to rise.

Compare the Market analysis shows a tertiary-educated single professional earning $125,000 would be able to borrow an extra $95,900 based on the announced changes.

The extra borrowing power for some earning $100,000 would be more than $56,000, whereas a person earning $75,000 can borrow an additional $26,800.

The Coalition opposition has also promised to allow home buyers to raid their superannuation savings for a deposit, and it has committed to watering down responsible lending obligations.

These policies would boost housing demand and increase mortgage debt, driving prices higher. As a result, they would make the affordability situation worse.
