John Curtin raised his ire with a speech he made to the Australian people declaring the nation's loyalty to the USA with Australia's declaration of war on Japan, which was a sensible thing to do - the NZ Prime Minister had cemented relations with the USA before Pearl Harbour. Churchill was angered by Curtin's declarations, even FDR stated he was panicking. Nevertheless the speech pretty much let everyone know that the country was going into a wartime footing. He was a man who didn't mince his words at a time when Australia needed men who didn't mince their words.
