A traditional Aussie barbie has seen the Duke of Edinburgh showing off his culinary skills.
Philip could not resist entering into the spirit of the occasion and flipped a steak sizzling on a grill as he joined cooks attempting to hold a record-breaking barbecue.
The event was the last engagement in the Queen and Duke's 11-day tour of Australia, and the monarch told the crowds: "We have been overwhelmed by your kindness and support.
"Once again we will return to the United Kingdom with fond memories of our time here and the warm Australian welcome we have received on our 16th visit to this beautiful country."
The Queen has received a rapturous welcome during her tour and Perth residents followed the national mood and turned out in their tens of thousands for a final glimpse of the royal couple.
The visit has already secured its place in history as yesterday Prime Minister David Cameron, in Perth for a Commonwealth leaders' summit, secured the agreement of the 15 nations where the Queen is head of state for a change in the rules of succession which will put royal daughters on the same footing as sons.
Those in line for the throne will also be allowed to marry Roman Catholics for the first time in 300 years without giving up their claim.
The 85-year-old Queen's visit has been billed by commentators as her last in light of her age.
But Buckingham Palace has dismissed speculation that it was a farewell tour.
A royal source said: "The Queen and Duke have really enjoyed themselves. The Queen has been bowled over by the reaction."
