Politicians who vote to repeal Sydney's controversial lockout laws will have blood on their hands, a group of NSW emergency service workers say.
Police, doctors, nurses and other supporters of the Last Drinks campaign on Wednesday gathered outside NSW parliament ahead of a debate on a bill to scrap laws that prevent people from entering licensed venues after 1.30am.
The Shooters, Fishers and Farmers Party introduced the legislation to parliament in October.
Shooters MP Robert Borsak said at the time his party believed in "freedom of choice".
But Last Drinks spokesman Tony Sara said the laws - in place since 2014 - have saved lives and prevented thousands of injuries.
He said St Vincent's Hospital had seen a 50 per cent drop in serious overnight head injuries and it would be "reckless" for any politicians to overturn the laws.
Dr Sara warned politicians repealing the laws would return Sydney to "the bad days of alcohol-fuelled violence, sexual assaults and deaths".
"Do not do this. If you do, there will be blood on your hands," Dr Sara told reporters.
"You speak to the parents of those young men who died - they see it as profits before lives."
Freshly-minted Labor leader Michael Daley is opposed to relaxing the laws but is open to other measures including rewarding good venues.
His unsuccessful challenger for the leadership, Chris Minns, last week said he would push for the lockout laws to be dumped if elected.
