Allrounder Shane Watson might have played his last one-day international for Australia after he was axed from the side that beat Afghanistan by a record 275 runs in the Cricket World Cup on Wednesday.
Watson, 33, has been an automatic selection by Australia, but struggled in the first two matches against England (duck and 0-13) and New Zealand (23 and didn't bowl).
Watson has only one half century in seven games this year, and has paid for the team's strength in depth at his third World Cup.
Australia picked allrounder James Faulkner instead at the WACA ground, and retained fledging allrounder Mitchell Marsh alongside him.
"Watto handled the decision well," skipper Michael Clarke said. "He has been fantastic around the team today. He's taken it really well."
