David Warner will miss the second and third one-day internationals against India as his wife is due to give birth, with Usman Khawaja called up to replace him.
Warner's wife Candice is expected to give birth to their second child imminently, but the opening batsman played in Australia's five-wicket win in the first game of the five-match series at the WACA on Tuesday.
However, the 29-year-old has made himself unavailable for selection for Friday's match in Brisbane and the third game of the series at the MCG on Sunday.
The in-form Khawaja is set to feature in his first ODI for almost two years after making such an impressive return to the Test side.
National selector Rod Marsh said: "Usman has been in fantastic form this season and was unlucky to miss out on a place in our squad for the Victoria Bitter ODI Series in the first place,
"This call-up is a reward for that form and it is great to have someone of his quality to step into the squad in David's absence.
"We wish both David and Candice well and look forward to welcoming David back into the squad when circumstances allow."
Rohit Sharma made a sublime 171 not out as India posted 309-3 in Perth, but captain Steve Smith (149) and George Bailey (112) put on 242 for the third wicket as Australia got home with four balls to spare.
