Fewer than half of Australians believe the country should become a republic, as about four million people tuned in to watch Queen Elizabeth II's funeral service.
Prime Minister Anthony Albanese is on his way back to Australia having joined more than 2000 people in Westminster Abbey for the state funeral, and related events.
While Mr Albanese has been reluctant to talk about an Australian republic out of respect for the Queen, a Guardian Essential poll published on Tuesday found 43 per cent support for the constitutional change.
