Pauline Hanson’s One Nation party has outlined a plan to offer 30-year fixed-rate mortgages at 5 per cent, a move that economists warn could expose the federal government to losses running into the hundreds of billions of dollars.

The proposal aims to undercut the major banks but carries significant fiscal risks, particularly during economic downturns when default rates typically rise.

The plan has drawn sharp criticism from Opposition Leader Angus Taylor, who has warned that the economic platform could destabilize Australia’s fiscal position and potentially trigger a sovereign debt crisis.

Taylor’s comments highlight the growing political tension surrounding housing affordability and the cost of living, which have become central issues in Australian politics.

The Reserve Bank of Australia’s ongoing campaign to curb persistent inflation has already generated significant political backlash, with voter frustration intensifying.

The disconnect between monetary policy and household financial stress has created a fertile ground for populist proposals like One Nation’s mortgage plan, which promises immediate relief but lacks a clear funding mechanism.
