Sydney DJs and club owners are warning that the city's music scene will be hit hard by laws targeting drunken violence.
Last week, parliament passed tough new government laws that will force venues to stop selling alcohol by 3am and will enforce a 1.30am lockout.
Sydney club owners and artists held a community forum at the Metro Theatre in Sydney on Monday, warning they stood to lose business and jobs because of the laws.
Murat Kilic, a DJ who runs The Spice Cellar club in the CBD, said he's had to restructure his business to focus on food rather than music because of the laws, and that he may be forced to sack half of his 50 casual and full-time staff.
"We've had no violence at our venue and we're getting punished for unfortunate deaths, which we are all absolutely against," he told AAP.
"We've already axed our jazz musicians. It's quite a tragedy."
Mark Gerber, who operates the Oxford Art Factory, said his business would likely lose a quarter of its revenue because of the new rules.
"That will mean a drastic cut in the art-based entertainment that we provide," he said.
He explained that late-night trading, the main target of the new laws, allowed clubs like his to finance live music and cultural events.
Mr Gerber said he was concerned some club patrons might turn to illegal drugs once venues stop selling alcohol at 3am.
The laws are expected to come into effect by April and will apply to hotels, nightclubs, bars and registered clubs in Sydney's CBD.
Controversially, The Star casino in Pyrmont and the area of Barangaroo, where James Packer is planning to build a hotel and casino, are exempt from the laws.
