The coalition has signalled it could cross the political divide and work with the Greens to stop contentious tax changes going through parliament, as the prime minister also tries to get the minor party on side.
The tax changes, which will limit negative gearing on properties to new homes from July 2027 and scrap a 50 per cent discount on the capital gains tax for a rate tied to inflation, passed the House of Representatives on Thursday.
The bill will be voted on in the Senate after a rapid-fire inquiry examining the tax overhaul later in June.
The passage of the laws remains unclear, as the government needs support from the Greens to get the changes through.
Opposition Leader Angus Taylor said the coalition, which have already come out against the tax changes, were willing to work with the Greens on voting down the measures.
