GRAPHIC and bloody footage of violent booze-fuelled brawls have been made public by NSW police, as part of their bid for statewide curbs on the sale of alcohol in pubs and clubs.

The Police Association of NSW claims politicians don't want the public to see the shocking five-minute video, which reveals explicit scenes of mass brawls, horrific injuries and extreme violence on the streets of Wollongong.



One particularly graphic part shows a man being knocked unconscious during a brawl.



He's then kicked extremely hard in the face while lying motionless on the ground, sending his head jerking sharply backwards. A close-up later shows a mass of blood pouring from his face.



The union has released the CCTV footage to try to sting lawmakers - who it accuses of inaction and "foolhardy" policies - to address the issue.



"You can't bury your head in the sand any more, politicians actually have to step up and do their job, that is protecting the community," police association president Scott Weber said in Sydney.



The union is demanding a three-month trial across NSW of 3am closing times, 1am lock-outs and restrictions on the sale of high alcohol content drinks in pubs and clubs.



It would be in line with a three-month trial in Newcastle, largely seen by police and politicians as helping reduce alcohol-related violence in the city, and would affect 320 premises.



Mr Weber also called on both sides of state politics to make the issue of tackling alcohol-fuelled crime a key issue for the March 26 state election.



"I don't think they (politicians) actually have the strategies. I think there's been powerful lobby groups in place ... sitting there telling them not to go down this path," Mr Weber said.



He accused the State Government of sitting on its hands over the issue.



State Labor's Hassle Free Nights policy, which targets some of the state's most violent entertainment districts, was "foolhardy", he added.



"We're seeing Communities NSW, we're seeing the Government not act in regards to this, keeping the community safe," Mr Weber said.



He said an application to restrict sales of alcohol in Wollongong was made 15 months ago but has not been implemented because of "red tape".
