Backbenchers should challenge senior ministers in relation to the super tax policy when the Coalition party room meets.

“Even the cabinet appears to be split with reports that Julie Bishop, Chris Pyne, Peter Dutton and Barnaby Joyce have expressed concerns about the voter backlash but have been rebuffed by Malcolm Turnbull, Scott Morrison and George Brandis,” said Mr Fairweather.

“The Coalition backbench should insist on a review of the controversial superannuation changes before they are introduced to the parliament in legislation.”

Mr Fairweather said Labor should refuse to pass the superannuation legislation in parliament until it has been independently reviewed.

“The Tax White Paper process was stopped in its tracks and the review of the objective of superannuation just went through the motions to justify decisions made in the budget.”
