A majority of voters would not mind if Australia Day was shifted to a different date and most don't know why it's currently held on January 26.

New polling also reveals that only about a third of Australians – 37 per cent – realise the date is offensive to many Indigenous people because it represents the beginning of the dispossession and violence of British colonisation.

As the political and community debate about the "change the date" movement continues to intensify, the Research Now survey of 1417 people suggests nearly all Australians – 84 per cent – think it is important the country has a national day of celebration.

But 56 per cent say they don't mind when the day occurs, challenging the notion that Australians see January 26 as sacred or untouchable.
