Support for Australia becoming a republic appears to be waning, with just one in three Australians in favour of the idea.
An online poll conducted for Nine Entertainment has found 40 per cent of people oppose replacing the British monarchy with an Australian head of state.
One quarter of the 1222 surveyed said they didn't know, which is the highest number of undecided responses recorded by successive Ipsos and Nielsen polls.
The polls indicate support has steadily declined from a peak of 57 per cent in December 1999, immediately after the failed republic referendum.
In the latest poll, support levels were weakest among young people aged between 18 and 24, while Labor and Greens voters were more likely to want a republic than coalition voters.
Australian Republican Movement chair Peter FitzSimons played down the results and suggested the poll was an outlier.
He pointed to a YouGov survey from July last year that found 62 per cent of Australians would vote for a republic.
Mr FitzSimons said the republican movement had been relatively quiet during the coronavirus pandemic but would ramp its campaign up again in coming months.
Former prime minister Malcolm Turnbull spearheaded the failed republic referendum movement.
He believes the date Australia becomes a republic should be the new national day.
But polling published by Nine Entertainment suggests support for changing the date of Australia Day is also not that strong.
