Firstly, the 26th of January does not mark the formation of the nation of Australia. The Federation, when all state colonies came together to form the Commonwealth, happened on 1 January 1901.
Secondly, the 26th of January has not always been the date for Australia Day.
Thirdly most Australians don’t care about the date.
So much for “uniting Australia” — divide and conquer is the Liberal way. It takes a pretty special leader to use the national day to drive a deeper wedge into the nation in an effort to bolster his languishing political fortunes….
