Joyce has yet to play Test cricket for England

The 28-year-old Irishman has only played three one-day internationals and a Twenty20 match for England so far.

But chairman of selectors David Graveney described him as a "highly promising player" who could cover a number of batting positions.

Trescothick returned home from Australia on Wednesday after a recurrence of a stress-related illness.

Interview: England's Ed Joyce

"I'm obviously sad for Marcus coming home but I'm really happy that I got the nod and I'm looking forward to getting out there," Joyce told BBC Five Live.

Joyce will fly out with the Academy squad on Wednesday but leave them in Dubai before joining the rest of the England squad in Adelaide.

It is unlikely he will make the team for the opening Test in Brisbane unless one of the other batsmen on tour suffers an injury.

He was chosen ahead of Academy team-mates Rob Key and Owais Shah, both of whom have previously represented England.

"Rob and Owais are very good players and have Test experience so they are probably disappointed not to get the nod ahead of me," said Joyce.

"But I knew I had a decent chance being involved in the one-day squad and hopefully I just impressed being around that."

Key, 27, was a losing Ashes tourist in 2002/03, but Joyce said recent shoulder surgery probably counted against the Kent batsman more than a perceived weakness against Australia.

"Rob performed pretty well on that trip and he impressed the Aussies with the way he played," said Joyce. "Maybe being on a losing side counted against him a bit but I don't think so.

"He's just unfortunate that he had injuries last year and has just had a shoulder operation. Whether he's fully recovered from that I don't know."

Joyce, who only qualified to play for England last year, averages 47 in first-class cricket and has 17 centuries to his credit, including a highest score of 211 for Middlesex against Warwickshire in July.

He has already been on one tour with England this winter, having been part of the Champions Trophy squad, but he did not play a single game in India.

Middlesex assistant coach Jason Pooley believes, however, that his call-up for the Ashes demonstrates continuity by the England selectors.

"I thought they might go for Rob Key because he did quite well in Australia before [in 2003-03], but it's great for Ed because he needs to test himself at that level," Pooley told BBC Sport.

"He's scored a lot of runs in county cricket for Middlesex. He's someone who likes to build and innings and plays at his own pace. He doesn't change the way he bats from nought to 100 really, he just bats with the same tempo.

"I don't think there are any flaws in his game now apart from gaining experience at that level. That will be the test - can he cope with international cricket and all the media and hype that goes with it?"

He added: "In the early part of his career, coming from Ireland where the pitches are a lot slower and lower, he was more of a front foot player, but he's developed over the last few years.

"I'm sure he'll be able to cope, but we don't have the quality of international seamers in county cricket that we used to have in the 90s, so now you only find out [if you're good enough] when you're in there.
