Kylie Minogue performed for Britain's Prince Charles and Duchess Camilla ahead of their tour of Australia next month.
The Australian-born singer - who now lives in London - believes the country will offer the royals a ''warm welcome'' when they tour the region to conclude Queen Elizabeth's Diamond Jubilee celebrations, on what will be Camilla's first trip to Australia.
Kylie told the BBC: ''I hope she has a beautiful warm welcome. I know that they will both enjoy the hospitality Australia offers. I'm sure currently at the other end of the earth they are planning the best time for them. I hope they enjoy it.''
However, fellow Aussie Barry Humphreys - best known as his alter-ego Dame Edna - joked he was worried the country's prime minister Julia Gillard, a known anti-monarchist, would not curtsey to the royals as was protocol, and urged someone to hit her ''behind the knees'' if she didn't.
He said: ''I think they'll have a wonderful time in Australia, if the prime minister can bring herself to curtsey. We're hoping she can.''
Asked what the chances were she might not, he laughed: ''I think someone has to hit her behind the knees with a very hard stick.''
