X-Men star Jackman was also asked what reception the Queen will get when she flies to Canberra.
He replied: “They love her there, the only issue I know is she cannot make every city.
“Even the republicans, the ones in Australia who want to see Australia move on, still have great respect and love for the Queen. I’ve never heard anyone say different.”
When asked what it was like to be at the palace, he joked: “As an Aussie it feels weird, I’m just waiting to get thrown out.”
In the palace’s opulent white drawing room the Australian celebrities gathered to be introduced to the Queen, Duke and Earl of Wessex, with the monarch showing no signs of her illness.
In the line-up alongside Macpherson and Jackman were actor and singer Jason Donovan, and Revel Horwood, but veteran entertainer Rolf Harris was missing – due to illness believed to be a cold.
The royal couple chatted to the Australian stars for a few minutes and shared a joke with the group before they greeted all their guests, who numbered almost 350, in turn.
Jackman said after meeting the Queen: “She was talking about the flight (to Australia), about travelling. I wanted to ask her if she was stopping off but didn’t think I was meant to ask questions.
“I did say ‘have a great trip to Australia’ and she said ‘thank you, I’m excited about it’.”
He joked about Macpherson, whose bikini-clad form appeared many times in American magazine Sports Illustrated, saying: “It’s always good to stand next to Elle.”
