The final 16 offers no real surprises, with the eleven who lined up in EnglandÃ¢â‚¬â„¢s last Test match against Pakistan all winning places on the tour.
Ian Bell and Tim Bresnan, who have both recently recovered from injury, join the party along with Surrey wicketkeeper Steven Davies to provide cover for Matt Prior.
Those who have narrowly missed out include Ajmal Shahzad and Adil Rashid, the latter after many had tipped him to cover for Graeme Swann after an outstanding summer.
National selector Geoff Miller explained the reasons behind the selections of Tremlett, Panesar and Davies.
He said: Ã¢â‚¬Å“We feel that Chris TremlettÃ¢â‚¬â„¢s inclusion will add a real threat of pace and bounce to our bowling attack given the conditions in Australia. Chris will be vying for a place in the final teamÃ¢â‚¬Â.
Panesar has been rewarded for hard work since his move to Sussex. Ã¢â‚¬Å“Monty has gone away and worked on his bowling since his last England appearance and he continued to be an attacking threat with the ball in his handÃ¢â‚¬Â, said Miller.
The selector also complimented Steven DaviesÃ¢â‚¬â„¢ improvements: Ã¢â‚¬Å“His glove work and batting have continued to reach new levelsÃ¢â‚¬Â.
