A Bulldogs board member who resigned over the Coffs Harbour scandal has backed hefty fines dished out by the National Rugby League club on players for bringing the game into disrepute.

Peter Mortimer was one of three high profile casualties during the fallout over Bulldogs players being investigated by police over rape allegations at pre-season camp at Coffs Harbour in February.

Mortimer resigned a day after his brother and ex-Bulldogs CEO Steve Mortimer walked away on March 22 while former club football manager Garry Hughes was sacked for failing to enforce the code of conduct and for "not acting in the players' interests" at Coffs Harbour.

After police announced in April that no charges would be laid following a 10-week investigation, the club said "several players" had been fined up to 25 per cent of their contract payments - believed to be totalling up to $100,000 - for conduct surrounding the Coffs Harbour camp.

Mortimer backed the club's actions despite the Bulldogs not detailing the fines, the number of players involved or their transgressions.

"There's been a lot of hurt. And the club has always said they will discipline the players concerned and they have done that, I don't think they have to name those players," he said.

"I think this will be better for all sport. I think this is a warning to all people who participate in sport."

The fines came after the NRL fined the Bulldogs $500,000 - $350,000 was suspended until the end of 2006 - for bringing the game into disrepute.

NRL chief executive David Gallop said the Bulldogs' actions was a positive for the sport after enduring months of fallout over the police investigation.

"What's pleasing is the attitude out at (Bulldogs' headquarters at) Belmore, which is that change is necessary, change is going to happen," he said.
