On 9 March 1942 four people were arrested in Perth on suspicion of a plot to contact the Japanese armed forces to help with a Japanese invasion and to assassinate public officials. They had formed an organisation called the Australia-First Group. A few days later 16 people, members of the Australia First Movement, were arrested in Sydney. In Parliament they were all denounced as traitors – because WWII was underway and Australia was in fear of a Japanese invasion. Two were sentenced to prison and most of the others were secretly interned for the duration of the war.

Australia Day is celebrated on 26 January each year. But how much do you really know about the history of Australia Day? 26 January is not the date the First Fleet arrived in Sydney Harbour, nor is it the day the Colony of NSW was  proclaimed. And it may surprise you that the first public holiday to be actually called Australia Day was held on 30 July, not 26 January.
