The minister charged with pulling together the Turnbull government's looming housing affordability package has suggested Australians could be allowed to use superannuation when buying their first home but that such a change would have to be a part of broader reforms. Assistant Treasurer Michael Sukkar, who is spruiking housing affordability as a key platform of the May budget, said any changes on the "demand side" such as superannuation reform could work if supply in the housing market was also increased.

"If all a government does is try to pump further liquidity into the residential housing market, inevitably all you do is push up housing prices," Mr Sukkar told Sky News on Tuesday.

In response to questions about super amendments being on the table, Mr Sukkar said 2014 comments from Finance Minister Mathias Cormann that allowing people to access super would only drive up house prices in isolation, were "largely correct," but any changes would be "finely calibrated to make sure we are not lazily pumping more money into the market."

"We've got to be a bit more sophisticated about it and I'm confident we will be," he said.
