Senator WONG (South Australia—Minister for Finance and Deregulation) (14:50): It is true that you have to have an eye to the effect of taxation on work and on investment. That is one of the reasons why this government is implementing an increase in the tax-free threshold, which will particularly ensure low-income Australians can receive more of every dollar they earn. That is an incentive to participation. That is ensuring that taxation instils the incentive to work. It is a good policy and it is a discredit the opposition that they are opposing it. But when— Opposition senators interjecting— The PRESIDENT: Order! Senator WONG: Thank you. In relation to carbon pricing and mining investment, I would make the point that we have seen private investment, including in the resources sector, increase since those two policies were announced. I also would make this point, but I do not think I have got time to do so, so I will have to do it another time.
