Mr Turnbull and Assistant Treasurer Kelly O'Dwyer both gave interviews to explain some aspects of the changes, arguing the transitional measures were instead being used as a tax minimisation tactic.

Another said there was "white hot rage" and a party room revolt could come after the election. Speaking in Brisbane on Wednesday, Mr Turnbull said the superannuation changes had been included in the May budget, which was "presented by the Treasurer and has the full support, naturally, of the government, the cabinet and the party room".

Sky News reported MPs and ministers had not been given so-called talking points or briefing notes outlining aspects of the changes, including to the transition to retirement scheme, and the party room had not considered the full package.

Mr Turnbull said the changes would make super "fairer and more flexible". "As everybody knows, our changes to super mean that 96 per cent of Australians in the super system are either better off or unaffected," he said.

"So yes, it does affect a small percentage and I can understand why people are disappointed by that but the consequence is that the system is fairer and more fit for purpose." He called the changes "important" and "overdue". Assistant Minister Alex Hawke called the changes to transition to retirement provisions a "niche issue" on Wednesday. Labor is likely to continue to seek to capitalise on the unrest. Cabinet secretary Arthur Sinodinos wouldn't speculate on a possible backdown and said any Liberal MP with concerns should "take it up with the Treasurer's office".
