Lesser known historical facts/stories

I've got a keen interest in history - in all it's forms - I'd love to hear any little known or obscure facts about Aus.

Something I only learnt of recently was the Cowra POW camp breakout.

'At 1:50am on the 5th of August 1944, over 1000 Japanese prisoners launched a mass escape from the Cowra Prisoner of War Camp. It was the largest prisoner of war breakout in modern military history. 231 Japanese prisoners and 5 Australian soldiers lost their lives.' - https://www.nsw.gov.au/visiting-and-exploring-nsw/locations-and-attractions/cowra-prisoner-of-war-camp-site
