A parliamentary committee chaired by prominent superannuation critic Andrew Bragg has upped the ante on the Coalition’s super for housing policy, suggesting first home buyers should be able to withdraw all their retirement savings to buy a house or use it as collateral to help borrow.

Modelling provided to the committee by actuaries Michael Rice and Jonathan Ng found a 35-year-old who used $160,000 from their super as a 20 per cent deposit on an $800,000 unit would have an apartment worth $1.2 million by retirement, but if that money had been kept in super it would have appreciated to $319,000.
