The issue is Space our national identity was in part founded 40000 years ago.Australia Day needs to stay on the 26th January!
On the 26th January 1949, the Australian nationality came into existence when the Nationality and Citizenship Act 1948 was enacted.
This was the day we were no longer considered British subjects and were permitted to travel with passports as Australians!
So it was at this point in our nations history that the Indigenous population also automatically became Australian citizens.
Therefore, 26th January was NOT the day the first fleet arrived. On the contrary it is a day which symbolises unity because it heralded the beginning of our national identity.
