For many Australians,   January 26 will be marked by beers, barbecues and Australian flag bikinis.
The Triple J Hottest 100 will blare from house parties around the country and pubs will swell with punters out to celebrate a rare Tuesday off work. 
For Indigenous Australians it will be a day of mourning. It marks the start of British invasion on Aboriginal lands and is an annual reminder of the many ways Aboriginal and Torres Strait Islander Australians are still being left behind.
Despite beginning to close the gap in life expectancy, Indigenous men, at 69.1 years, still trail their Anglo peers, at 79.7 years.
And while almost 73 per cent of non-indigenous 15- to 24-year-olds complete school to year 12, just 28.5 per cent of Indigenous young people achieve the same milestone.
Shireen Morris has worked with Aboriginal leader Noel Pearson at the Cape York Partnership for the past five years. As his main adviser on constitutional recognition, Ms Morris has focused on the need for mutual recognition.
"We've looked at other comparable western countries, liberal democracies like our own, with similar colonial histories - really, they are just miles ahead," Ms Morris said. "But for the first time, I do think we are getting really close, to the point where we are actually now ready to change the way we think about Indigenous issues because finally there is political will to address the question of constitutional recognition."
Last month a Referendum Council was appointed to progress the recognition of Aboriginal and Torres Strait Islander peoples in Australia's Constitution. No timeline has been set for the referendum. but former prime minister Tony Abbott previously nominated 2017 as the potential year in which it could be held.
Until then, Ms Morris said Australia could use Australia Day to better mark a national moment of recognition. "Noel Pearson says Australia Day should be a day to celebrate our Indigenous heritage, our British inheritance and our multicultural achievement," she said. "At the moment it's very anglo-oriented. Can we rethink Australia Day?"
Might there be a better date, the date we bring those three parts of the nation formally together and achieve reconciliation in a formal sense?"
Professor Richard Waterhouse, honorary associate in the University of Sydney's department of history, said the past 20 years has seen the day emerge as a "truly national day".
He said a transition in the past two decades has transformed the day to "one that features not only picnics and parties, but ceremonies celebrating Australia as a vibrant multicultural nation underpinned by the values of democracy and liberty".
