Australia's new high commissioner to the UK, Stephen Smith, says becoming a republic and scrapping the monarchy is "inevitable" but Australians remain proud to have King Charles as head of state.
Mr Smith told The Times newspaper that most British people would be "indifferent" to Australia getting rid of the monarchy and it would not damage the countries' relationship.
He said Australians were "absolutely" proud to have the King as their head of state.
Prime Minister Anthony Albanese has confirmed he will attend the coronation on May 6.
"There is a lot of affection and respect for the monarchy in Australia," Mr Smith said.
"That affection and respect hasn't gone away because of Australia contemplating from time to time what it should do about its constitutional arrangements."
Mr Smith said it was only a matter of time before the monarchy was abolished.
"My personal view is it's inevitable. But how that's progressed is entirely a matter for the Australian government of the day," he said.
