The family of an Australian father-of-four who collapsed and died at a rugby league carnival is outraged that play was allowed to go on despite the tragedy.

Front-row forward Fred Lemson, 40, collapsed of a massive heart attack as he walked off at half-time during the Queensland Rugby League-sanctioned All Blacks Carnival in Townsville last Saturday.

"Why didn't they call it off?" his grieving brother Darren Lemson said Friday.

"This was not a broken leg. Somebody died on that field. But they just didn't give a damn."

Organizers held a minute's silence before allowing play to go on.

The All Blacks Carnival is one of the biggest on the indigenous sporting calendar. It involves about 400 mostly indigenous players from 16 teams across northern Australia.

The popular Townsville Correctional Services officer’s funeral will be held on Monday.

His family has also raised questions about the standard of insurance and medical treatment available to the tournament, as well as the ambulance response time. Some have claimed it took half an hour before an ambulance was called. By then it was too late.
