Australia have called up batsman Mark Cosgrove and seamer Brett Dorey to replace Damien Martyn and Stuart Clark in their one-day squad in Bangladesh.
Seamer Dorey will replace Stuart Clark for Australia
Martyn has an elbow injury and Clark has returned to Sydney to attend the birth of his first child.
Left-hander Cosgrove, 21, has not played internationals before and was expected to join Glamorgan this month.
The 28-year-old Dorey played three matches in this year's one-day VB Series in Australia.
Bangladesh, meanwhile, have replaced Manjural Islam with middle-order batsman Tushar Imran for the one-dayers.
A spokesman for the Bangladesh Cricket Board said: "Imran will replace spinner Manjural Islam in a 14-man squad that completed a whitewash (4-0) against Kenya last month."
Tushar has played 33 international games in limited-overs cricket and scored 523 runs at an average of 16.34 runs.
The first of three one-day internationals against Bangladesh is scheduled for Sunday in Chittagong.
