This is a question for the Treasurer. Governments on both sides rely on bracket creep caused by inflation to increase tax over time and surreptitiously fund their additional spending. Do you agree that indexing tax brackets, like 17 other OECD countries have done, would stop us sleepwalking into greater reliance on income taxes and provide greater transparency for taxpayers about new spending?

Thank you to the honourable member for Curtin for her question. Obviously I'm aware there are a range of suggestions around about the next steps in income tax reform, while our focus has been delivering a tax cut for every Australian taxpayer. I do know that about half the OECD is taking the course that you're suggesting; that means about half the OECD isn't. Countries make their own decisions about these sorts of things. For us, one of the defining purposes of this Prime Minister and his government is to help people earn more and keep more of what they earn. The most important and fundamental part of that is about getting real wages growing again for consecutive quarters but also the tax cuts are playing a meaningful role as well.

There are, more or less, to oversimplify, three different ways that you can return bracket creep. There is the way that the member for Curtin is proposing. There is the way that those opposite were proposing, which is just to return bracket creep to people who are already on the highest incomes. Or there is the Labor way, the way that we have chosen to return bracket creep. As the Treasury analysis that we released a little over a year ago now when we made the changes to the tax cuts makes clear, the way that we chose has positive benefits for workforce participation and other benefits as well. So I do acknowledge that governments have choices to make when it comes to how we return bracket creep. We are frankly proud of the way that we've gone about returning bracket creep, because instead of giving a tax cut to some taxpayers, as those opposite were proposing, we are giving a tax cut to every Australian taxpayer. They are rolling out right now. They are helping Australians with these cost-of-living pressures which are enduring.

The final point I would make is this, and again I make this point respectfully. I listen to the member for Curtin and her colleagues on all of these sorts of issues in a genuine and respectful way. But the difference between the ideas which are offered up from the crossbench and the ideas that we are able to pick up and run with in government is we have to make it all add up. We have to make sure that our tax reform priorities are balanced with our priorities when it comes to public investment. We have to make sure that all of those things are calibrated. But, having said that, I say again that I thank the member for Curtin for her question and for her interest, along with other crossbench colleagues, in genuine tax reform. I note that genuine tax reform is being rolled out right now in the economy.
