Why? We already have enough of those days...Anniversary of the Apology, National Sorry Day, Anniversary of the 1967 Referendum, Mabo Day, International Day of Indigenous People, National Aboriginal and Torres St Islander Children's Day, NAIDOC Week and Reconciliation Week.
The past can not be changed, but the Australian Government provides many educational and general resources for these days, for the nation to be inclusive of Indigenous culture, and encourage Australians to reflect and celebrate Indigenous culture and heritage.
Bring on Australia Day.
