My question is to the Prime Minister. Labor legend Bill Kelty has declared the Treasurer's economic model a failure, and Labor's own backbench are leaking against him, saying Australians aren't buying the Treasurer's spin. Now, the Australian Financial Review reports that the Treasurer has switched back to using the 30-year average from the 20-year average for productivity in order to pump up his numbers. With cooking the books the only answer to Australia's economic crisis, how many more chances does the Prime Minister intend to give his failing treasurer?
