Twin fights over tax and disability support will dominate parliament in the coming days as the government tries to ram through reforms before MPs leave Canberra for the long winter break.
Labor is attempting to hash out a deal with the Greens to pass controversial changes to capital gains tax and negative gearing, in exchange for extending an inquiry into a planned overhaul of the NDIS.
The Greens are pushing for the tax changes to apply to all properties instead of the current proposed grandfathering arrangements.
Opposition Leader Angus Taylor said the tax changes should be scrapped and accused Labor of shifting to the "crazy left" to do an agreement with the minor party.
"That dirty deal between Labor and the Greens is, I think, something every Australian should be deeply concerned about," he told reporters in Canberra on Monday.
