Uncapped Mahli Beardman and Jack Edwards have been named in Australia's 17-man squad for the three-match T20I tour of Pakistan, with only 10 members of the T20 World Cup squad set to feature in the series.

Nathan Ellis, Tim David, Josh Hazlewood, Glenn Maxwell and Pat Cummins will instead join the squad in Sri Lanka as they return from injury and workloads are managed into the World Cup.

Bailey revealed that David, who is recovering from a hamstring strain, had a "minor setback" in his rehab last week, when he wasn't able to complete a running session. "But he has since been cleared of any damage," Bailey said of David. "It was just on the back of a heavy week, so he's still tracking for the start of the tournament; Josh (Hazlewood) is in the same boat."

Edwards has picked 15 wickets for Sydney Sixers in the ongoing Big Bash League season whereas Beardman, 20, has impressed with eight scalps for Perth Scorchers.

Sean Abbott, Beardman, Ben Dwarshuis, Edwards, Mitch Owen, Josh Phillippe and Matt Renshaw are the other players who have come into the squad that will once again be led by Mitchell Marsh.

Australia will play Pakistan in three T20Is at Gaddafi Stadium in Lahore on January 29, 31 and February 1, with players involved in the BBL finals joining the squad once their domestic commitments are complete. Australia's opening World Cup match is against Ireland on February 11.

"The series is a great opportunity for those on the brink of selection and some young players we rate highly for valuable experience with the World Cup group in Pakistan," Chair of Selectors George Bailey said.

"Some are already experienced international players along with Mahli Beardman who has been with the group a number of times and Jack Edwards who joined for the last one-day match against India in Sydney last year."
