Originally set to take place throughout August, Vivid Sydney will now begin in September and run through to October.
The news comes as a COVID-19 outbreak emerges in the city.
“We all want to see Sydney shine through the spectacular show of creativity and innovation that is Vivid Sydney in September and October this year,” Minister for Jobs, Investment, Tourism and Western Sydney Stuart Ayres says.
“The recent outbreak has presented a new challenge for everyone, and the health and safety of our citizens and entire event community involved in Vivid Sydney is our foremost concern.”
Stuart says Vivid will only proceed if it is safe to do so.
"Destination NSW will continue to work with NSW Health and other agencies to deliver a COVID-safe Vivid Sydney later this year, with support from our event partners, artists, sponsors, and suppliers."
Full details of a revised Vivid line-up will be available online soon. Ticketholders will be able to transfer their ticket to the new event dates, or request a refund via the relevant ticket agent.
