Did you know Australia and the UK (and Australia) almost went to war in the 1930s? The British Government was pressuring the Australian Government to repay the 'debt' of the military supplies given to Australian to help in WW1. So the UK asks Australia to help with their war, gives them equipment to facilitate involvement, and then expects to be paid back for everything. The Prime Minister wasn't a powerful office at the time and had his hands full with the NSW Premier Jack Lang that outright refused to pay the 'debt' the UK, stating that it was illegal as it would reduce the Australian economy and people to 'slaves' of the UK. The PM was allied with the UK and had the (weakened) military on his books, but Jack Lang had the police on his books, leading to staunch confrontations that luckily never ended in violence. I cannot stress how close the country came to collapsing over this crisis, Lang's actions of moving state money into holding of a private bank (to prevent being funds being paid to the UK) were deemed illegal and his government was dissolved, but not without half of Sydney protesting the result.
