No doubt true, but most of it is still because over 45’s have been upgrading their houses with 30 year mortgages. Money in the house (unlike super) is exempt from the asset test so allows for a bigger Age Pension. This is what advisors will (and should) tell them. Government should either stop the banks from offering mortgages that go beyond a reasonable retirement date or include part of the house in the asset test - or both.
First time home buyers could be exempt from mortgage restrictions. The future will be different because there are growing numbers who cannot get buy their homes until later in life.
