Australia will have at least two debutants in the first Test against Pakistan in Dubai starting on Sunday.
South Australia captain Travis Head and white-ball specialist batsman Aaron Finch will play in their first Test match, while Marnus Labuschagne could become the third debutant.
Coach Justin Langer has confirmed Head and Finch will play, after they scored half-centuries in Australia's drawn tour match against a Pakistan A side.
Langer says he can't wait to see Finch play Test cricket, adding: "He's been great in white-ball cricket for the last couple of years, he's obviously got the temperament for international cricket."
He said Head had improved hugely over the last six months, and was now a much better player against spin.
Labuschagne could come in for opener Matthew Renshaw.
Langer expects Renshaw to be fine physically, after being struck in the head by the ball during the four-day tour match.
But the coach says the doubt with him is that he has not played much cricket recently as he picked up a hamstring strain on the Australia A trip.
"That's going to be the issue for him; it's going to be an instinct call," added Langer.
"We've got to weigh up what he's done in the past - he's obviously a very good young player. We've got to work out whether he's spent enough time out in the middle to be ready for a Test match."
Labuschagne, who scored an unbeaten 39 in Australia's only innings in the tour match, can also bowl part-time legspin.
Australia are likely to opt for a second paceman to support left-armer Mitchell Starc and could turn to uncapped Queensland quick Michael Neser.
Australia are 12/5 to win the first Test, with Pakistan 7/10 and the draw 5/1.
