NRL club the Bulldogs and Telstra Stadium on Thursday night unveiled tough new measures in the wake of last Friday night's crowd trouble.

A "large firework" was detonated late in the Bulldogs' round 20 clash against Brisbane at Telstra Stadium, marring the Canterbury side's victory over the NRL ladder leader.

The Bulldogs, NSW Police and Telstra Stadium are still working together to apprehend the crowd members who detonated the explosive device.

As a result, the Bulldogs on Thursday night revealed a raft of changes to be introduced at future home games "effective immediately".

They include reserved seating only being available for fans, identification required when purchasing a ticket and the banning of drums, oversized flags and banners.

And Telstra Stadium - which shares Bulldogs home games with Sydney Showground - revealed new measures including compulsory bag inspections for all patrons, NSW Police sniffer dogs at all public entrances, more targetted use of CCTV surveillance system and increased security presence.

"I hope Bulldogs fans realise the position the club has been placed in and will support the decision," Bulldogs chief executive Malcolm Noad said in a statement.

"Our motive, first and foremost, is that fans who come along to our games will not have to put up with a small band of hooligans whose goal is to disrupt others."

The Bulldogs measures, in full, are:
