Absolutely, but they'd be crucified if they went back on their election promise to keep the stage 3 cuts. They'd never hear the end of it.

I reckon they'll wait things out for this term while economic conditions keep the budget in surplus, then take a policy to the next election for some kind of specific levy - maybe an NDIS levy - to try to claw back some revenue as the budget balance is forecast to turn south.

They did say before the last election that they'd make multinational corporations pay their fair share in tax, so that's one area they could make changes to raise revenue, but anything they were going to do there they would have already done by now.
