Bali is a popular destination for Australian sports teams on end-of-season trips, and several Australian Rules Football and rugby players are feared to be among the dead or missing.

The official death toll of Australians was 13 on Monday, but with 220 still unaccounted for, that figure was certain to rise.

Aussie Rules star Jason McCartney is in intensive care in Melbourne's Alfred Hospital with serious burns suffered in the bomb blast.

The 28-year-old was airlifted to hospital on Tuesday when it became apparent that his injuries were far more serious than at first thought.

The wife of former Australian rugby league international Craig Salvatori was among those killed at the Sari nightclub where the first bomb exploded on Saturday.

The couple and their two daughters had been holidaying on Bali.

Of the many amateur Australian Rules football clubs celebrating the end of the season on the island, one club from Perth was still missing seven members.

The club's coach, Simon Quayle, said he had scoured the hospitals in search of his friends and vowed to leave the island "as a team", just as it had arrived.

The attack has led four clubs from Australia's National Rugby League to cancel planned end-of-season trips to Bali.

St George Illawarra, the Northern Eagles, the Melbourne Storm and the Brisbane Broncos were due to leave for Bali this week to celebrate the end of the NRL season.

Meanwhile, England's Rugby Football Union has offered condolences and support to relatives and friends of players affected by the explosion.

As a mark of respect, a minute's silence is planned at all domestic league matches next weekend.

The RFU will also write to all unions affected by the tragedy, conveying their sympathies.

"Everyone has been deeply distressed by the events in Bali," said Terry Burwell, the RFU's community rugby director.

"The rugby community has lost a number of its players and members, and our deepest condolences go out to their friends and family."
