Prime Minister Anthony Albanese says it is clear King Charles has a great affection for Australia, confirming he has invited the monarch to visit.
Mr Albanese described the private audience he had with the King at Buckingham Palace, on Tuesday local time, as "very warm".
"I appreciated the discussion that we had and that King Charles has a great love for and affection for Australia," Mr Albanese told reporters while visiting Barrow-in-Furness in northern England on Wednesday.
"It comes from his time as a student there but also his many visits to Australia."
The prime minister's comments come as a YouGov poll, published in The Australian, shows more than 50 per cent of his constituents have a positive view of the monarch.
But King Charles' approval rating among Australians in the May survey has improved from the 43 per cent who had a positive opinion of the royal in April 2021.
Prince William and his wife Kate remain the most popular royals, while Queen Camilla is among the least popular.
Mr Albanese, a republican, said he was looking forward to being at the monarch's coronation ceremony on Saturday and the King was "very familiar with the range of issues that Australia is facing".
The prime minister said he had extended an invitation to visit Australia during the meeting.
"I can confirm that I once again reiterated that King Charles and Queen Camilla would be very welcome visitors to Australia as would any other member of the royal family."
The YouGov poll revealed 43 per cent of the Australians surveyed had no interest in the coronation, while the remainder said they had at least a little interest.
Older people were more likely to be interested in the coronation, while support was lowest amongst generation Z.
Mr Albanese is among a contingent of Australians invited to the coronation along with Governor-General David Hurley and state governors.
The Australian delegation includes Matildas captain and football star Sam Kerr, singer Nick Cave, Aboriginal artist Jasmine Coe, comedian Adam Hills and London-based nurse Emily Regan.
In honour of the coronation, the Australian government will contribute $10,000 to the West Australian conservation charity Friends of the Western Ground Parrot.
Mr Albanese said King Charles long championed conservation and the government was pleased to mark the event by helping to protect the critically endangered bird.
The King, who is the monarch of 14 overseas realms including Australia, will host a lunch for prime ministers and governors-general at Buckingham Palace and also attend a Commonwealth Heads of Government Meeting on Friday, the day before his crowning.
On Sunday, Australia's Federation Guard will fire a national 21-gun salute from the Parliament House Forecourt, followed by a Royal Australian Air Force flypast.
