Australia have dropped three players for the third Ashes Test, with left-arm spinner Michael Beer a surprise selection for the match in Perth which starts on Thursday
The hosts have dropped Marcus North, Doug Bollinger and Xavier Doherty for the third Test as Australia look to level the series.
Beer, who has made only five first-class appearances for Australia, is joined by leg-spinner Steve Smith in a 12-man squad.
Ben Hilfenhaus and Mitchell Johnson, who both played in the first Test in Brisbane but were dropped for the defeat in Adelaide, are back in contention, while Phillip Hughes comes in for Simon Katich who is injured.
26-year-old Beer said: "I'm very much stoked and surprised. I don't think it really sank in until I rang my parents and blurted it out myself and thought, hang on, what's going on here?"
Australia's chairman of selectors, Andrew Hilditch, said of his decision to drop North: "This is obviously disappointing for Marcus who has played some outstanding Test innings for Australia
"But it was felt to be the right time to bring the exciting prospect Steve Smith into the Test team. Steve has already had success at international level and will also add to the bowling depth with his leg-spin bowling and dynamic fielding."
He added: "Johnson and Hilfenhaus will be strongly considered for selection in Perth, where conditions will suit them."
Australia squad: Ricky Ponting (captain), Michael Clarke (vice-captain), Shane Watson, Phil Hughes, Mike Hussey, Steve Smith, Brad Haddin, Michael Beer, Ryan Harris, Mitchell Johnson, Peter Siddle, Ben Hilfenhaus.
