Big Top Sydney

The venue was originally proposed in 1999 by Metro Edgley Pty Ltd. as the replacement for the troubled Big Dipper.^[3] Known as Luna Circus, the building was proposed as a venue for circus acts and a possible site for a permanent Cirque du Soleil show. Plans were underway to begin construction in 2000, opening in 2001.^[4] However, the proposal was not approved by the North Sydney Council until December 2002. Construction began in February 2003 and was completed in December.

The Big Top stands in place of the park's former Ghost Train, which burnt down in the 1979 Sydney Ghost Train fire that claimed seven lives. The fire's victims are memorialised with a plaque at the Big Top entrance.

An opening celebration concert was held 2 April 2004.^[5] It was hosted by Simon Burke and featured performances by Caroline O'Connor, Marina Prior and David Campbell. The first official event held at the venue was a performance of Sunset Boulevard (featuring Judi Connelli and Michael Cormick) on 3 April 2004.^[6]

In 2023, the venue received an extensive interior refurbishment. The main auditorium was fitted with 360 projectors, LED screens and holographic technology, allowing for the showing of "immersive experiences".^[7] The refurbished venue opened on 22 December 2023, with its premiere show named Dream Circus.^[8]

Since Big Top's refurbishment, it has been primarily utilised for upcharge pre-recorded shows targeted at Luna Park guests.^[9] As of 2025, Big Top's official website advertises the site as a corporate functions venue.
