With both nations already out of medal contention, the Sharks beat Kazakhstan 15-7 at Tatsumi Water Polo Centre on Monday night.

Australia, also featuring New Lambton's Nathan Power, were up 7-1 at half-time.

Campbell netted in the first and third quarters, giving him a career-best nine goals for this campaign.

The 33-year-old now has 28 goals to his name from appearances in Beijing (2008), London (2012), Rio (2016) and Tokyo (2021).

The Sharks were ranked ninth overall and fell short of qualifying for this week's quarter-finals.

Australia finished fifth in group B, dropping below Montenegro on goal difference despite having the same competition points from a 2-3 record.

The Sharks were defeated by Montenegro 15-10 in the opening fixture, but rebounded to upset Croatia 11-8. They had back-to-back losses against Serbia (14-8) and Spain (16-5).

"We've got a group that's been together for a long time, with plenty of experience," goalkeeper Joel Dennerley told AOC media.

"We know our preparation was quite strong, in terms of our conditioning, philosophy and tactics.

"The lack of match experience we've had in the last couple of years probably caught up with us a little bit. But that doesn't take away from the belief that we could do something special here."

Australian coach Elvis Fatkovic has now ended his time at the helm.
