Prime Minister Malcolm Turnbull has finally killed off the GST debate.
Now his treasurer has the opportunity to refine the broader discussion surrounding tax reform.
Scott Morrison will make his first appearance at Canberra's National Press Club as treasurer on Wednesday just months out from his debut budget.
Shadow treasurer Chris Bowen says the treasurer must come to the event tabling policies rather than just slogans.
But Mr Morrison says he won't be rushed into announcing decisions without careful consideration, although he made it clear that government expenditure must be brought under control.
"If you can't get expenditure low then you can't get taxes low," he said on Tuesday.
Mr Morrison will also likely touch on Labor's latest effort at tax reform - limiting negative gearing to newly constructed properties and cutting the capital gains tax discount to 25 per cent from 50 per cent.
Mr Turnbull and other cabinet ministers, while dismissing Labor's plan as poorly designed, say they are looking at negative gearing as part of their tax reform plan.
But backbenchers like Liberal ACT senator Zed Seselja says the government should tread very carefully in this area, believing it will damage the property market and confidence.
New figures on Tuesday showed consumer confidence rising two per cent in the past week, seemingly oblivious to the heightened debate over tax reform.
Commonwealth Securities chief economist Craig James doesn't believe proposed negative gearing changes would influence confidence levels as few will be affected.
He said the plan mainly applied to high income earners with large property holdings.
