Australia day should celebrate neither the british arrival or the indiginous culture beforehand. neither of those things represent australia the country. they only represent what happened before australia became a unified country and people.Is Australia day meant to be about celebrating aspect of British culture transplanted to Australia?
The conversation is moving towards having an Australia Day that doesn't focus on a particular day of arrival by some British outcasts, but rather a day that encompasses the heritage of those who were here for ~50,000 years + arrivals later than that and the current crop of people who are Australian.
Better to pick a month, then a random day in that month to celebrate and start Australia day anew
