The Australian Monarchist League said the results were not surprising and still showed less than one-third of Australians wanted to shift.

No Republic campaign chair Eric Abetz said more Australians still wanted to remain with "our tried true and trusted constitutional monarchy".

"The more life experience people have the more they value the institutions that have served them and their country so very well," Mr Abetz told AAP.

The poll of more than 1200 people found 12 per cent wanted Australia to become a republic once King Charles dies, down 12 percentage points.

The Queen died on September 8 last year aged 96 after reigning for more than 70 years.

Her death sparked renewed calls among the republican movement for Australia to embrace a change in its relationship with Britain, describing an eventual shift to a republic as inevitable.

That could be reflected in the latest poll which found about half of those quizzed believe Australia will not be a constitutional monarchy in 100 years' time. Only 19 per cent think it will.

But while Australians remain divided on the issue of a republic, the royal family continues to be popular with 34 per cent thinking the monarchy is good for the country.

The poll found 54 per cent have a generally positive view of the royals with Prince William, the next in line to the throne and with 69 per cent support, substantially more popular than his father.

Catherine the Princess of Wales, Princess Anne and Prince Edward are also liked by Aussies but the same support doesn't extend to Camilla, the Queen Consort, the embattled Prince Andrew, and Prince Harry and his wife Meghan.

A similar poll conducted among Britons found 62 per cent believe the United Kingdom should continue to have a monarchy while 26 per cent would prefer it to have an elected head of state.

Not surprisingly, both polls found support for the monarchy was highest among those over 65 and was lower among younger age groups.
