Pictures: The Queen and Prince Philip visit Australia
The Queen and the Duke of Edinburgh arrive in Australia's capital, Canberra to start an 11-day tour of the country.
Some people think this could be the Queen's last visit to Australia because it's such a long journey to make and she's in her eighties. These children from a local school have given her a cuddly toy and more flowers.
On her to-do list this time is a visit to Brisbane where she will meet people who were affected in the recent floods there. She's also going to have a day trip to Melbourne.
The Queen will also go to a three-day meeting of Commonwealth leaders in Perth.
After a warm welcome at the airport, the Queen and Prince Philip are ready to be driven to their next appointment. The trip will end on October 29 with a big Aussie barbecue.
The Queen arrives in Australia's capital, Canberra for the start of her 11-day tour of the country. A big crowd including lots of schoolkids has gathered to greet her and Prince Philip.
It's the 16th time she's visited the country, but it's been five years since her last visit. Crowds of people are waving flags and taking pictures.
