Opener Phil Hughes will replace the injured Simon Katich in one of four changes to Australia's 12-man squad for next week's third Ashes Test in Perth.

Australia, beaten by an innings and 71 runs in Adelaide and therefore 1-0 down with three matches to play, have also recalled fast bowler Mitchell Johnson and called up spinners Steve Smith and Michael Beer.

WA batsman Marcus North, fast bowler Doug Bollinger and slow left-armer Xavier Doherty are the three players dropped after Australia's second-Test defeat.

Beer was the least anticipated of the new selections, although Shane Warne - fancifully touted in some quarters for a return from retirement as Australia struggle in the series - had nominated the WA slow left-armer as a possible replacement for Xavier Doherty.

Warne has turned out to be spot on about a cricketer with just five first-class matches under his belt.

Explaining the reasons behind the squad announced on Friday afternoon, national selection panel chairman Andrew Hilditch said: "Phil (Hughes) is an exciting young batsman, who has already proven his ability to succeed at international level - and he deserves this opportunity to return to the Australian side."

Hilditch added: "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."

Beer appears to have an obvious chance of a Test debut, on his adopted home ground, having moved from club cricket in Victoria for a shot at the professional game this year.

"Michael is a left-arm orthodox spinner, who has been very impressive at domestic level this year," added Hilditch. "He took wickets against England in the tour match earlier this summer, and we expect he will bowl very well against the English on his home ground."
