Greens and Invasion Day., page-31

Australia became a nation on Jan 1st 1901.

A day that is remembered for some British ships (not the first) arriving and the British flag being raised in Sydney cove seems more like it should be British day. No Australian flags raise in 1788 jan 26, That name had not even been coined back then, the Brits called id New Holland anyway.

would be nothing wrong with changing the date to when we become a nation and an extra day off after new years day in my books
