City of Sydney Council staff have been tasked with developing a new strategy to promote Sydney as a "world class" late night city.

Lord Mayor Clover Moore said the new plan will include late night operating hours for museums, art galleries, cafes and retail outlets.

“We want a thriving and diverse night time economy,” Cr Moore said in a statement.

“Currently most cultural venues and cafes operate normal business hours and are not often open till late.

“It needs to change – it’s time Sydney catches up to the rest of the world.”

Cr Moore said the policy would be developed in consultation with the State Government, NSW Police, Transport NSW, the liquor industry and the community.

The strategy forms part of the Lord Mayor’s broader plan to curtail alcohol and drug related violence.

Cr Moore said the City would soon implement a range of measures to improve community safety late at night, including: a 12-week trial of late night ‘Precinct Ambassadors’ on George Street; a trail of new directional signage to improve access to transport and public facilities; and improvements to the Bayswater Road secure taxi rank in Kings Cross.
