Premier Barry O'Farrell should urgently recall MPs from their summer break to enforce lockouts and early closing times on Sydney's pubs and clubs, the opposition says.

The call adds to criticism from medical specialists and community activists that the government is failing to stem a tide of booze-fuelled attacks, including an alleged unprovoked assault on teenager Daniel Christie in Kings Cross on New Year's Eve. The teenager remains on life support at St Vincent's Hospital with a fractured skull.

Labor health spokesman Andrew McDonald said the senseless violence was a serious public health issue and Mr O'Farrell must "find his guts". "Until [the Premier] acts, we will see lives ruined, emergency departments turned into zoos and our streets too dangerous to walk on," he said.

"[The alcohol industry] and the Liberal Party are in bed together … and our young people are the ones who are suffering."

Labor wants the so-called Newcastle solution - 1am lockouts, 3am closures and a ban on shots after 10pm - trialled in central Sydney and Kings Cross.

Mr O'Farrell has refused to consider extending the Newcastle measures, despite his position in 2008 when, as opposition leader, he said a universal 3am closing time for pubs and clubs must be on the agenda.

On Friday, Hospitality Minister George Souris pointed to a recent independent review of liquor laws that calls for tailored solutions rather than a "one size fits all" response.

He said powers already exist under the Liquor Act to crack down on licensed venues including lockouts and bans on shots.

Mr Souris said crime figures showed the government's strategy in Kings Cross had led to a significant reduction in violent incidents in licensed premises, which "challenges the claim that Newcastle-style restrictions are the only pathway to achieving real reductions in alcohol-related violence".

However Mr O'Farrell said this week that while the number of assaults in NSW had fallen, there had been "a horrifying increase in the level of violence used".

He also said that given the early-evening timing of the assaults on Mr Christie and Thomas Kelly, who died in a similar Kings Cross assault in July 2012, ''Newcastle model'' 1am lockouts would have provided no protection.

The Australian Hotels Association NSW vehemently opposes blanket lockouts and early closing times, saying the issue of alcohol-related violence runs "far deeper" than licensing measures.

Mr McDonald challenged the government to call an emergency sitting of Parliament to pass the measures, saying "this could be brought into policy by next Friday … we can get [MPs] back from wherever they are".

The City of Sydney has refused to say whether it supports a trial introduction of the Newcastle model. However blanket 3am closures of licensed venues would appear to undermine the council's Open Sydney strategy, which aims to provide a variety of late-night activities.

Lord mayor Clover Moore said well-run late-night venues could be "a welcome part of Sydney's diversity and culture".

A council spokesman said it had sought "real solutions", including support for a freeze on new liquor licences and banning orders for violent patrons.

Sydney independent MP Alex Greenwich said a Sydney trial of the Newcastle model should be considered as part of measures to curb violent assaults, along with better transport and enforcement and more police.

But he cautioned that lockouts in central entertainment areas of Sydney could shift alcohol problems to other suburbs, leading to "illegal parties or street drinking".
