Sydney's main exhibition and convention centre. This new convention centre was built to replace the old convention centre and the Sydney Entertainment Centre to the tune of $1.5 billion. The centre is used for exhibitions across the year, as well as for music acts, talks and concerts in the two large theaters on either side of Exhibition centre.

The International Convention Centre Sydney (also known as ICC Sydney) is a convention and exhibition centre in Sydney, New South Wales, Australia. The centre opened in December 2016 as a replacement for the Sydney Convention and Exhibition Centre, which was demolished in 2013. ICC Sydney has over 70 meeting rooms, three theatres, and two formal ballrooms. The theatre within the centre has been known as the TikTok Entertainment Centre under a naming rights partnership with social media platform, TikTok, since November 2025.

ICC Sydney includes convention spaces for 2,500, 1,000, and 750 people. It also includes a flexible space of 2,500 square metres (27,000 sq ft) and the largest ballroom in Sydney, able to accommodate 2,000 people. The ICC Exhibition Centre and Entertainment Centre includes 33,000 square metres (360,000 sq ft) of exhibition space, which can be divided into smaller spaces according to requirements. The first major event held at the newly-developed centre was RTX Sydney, hosted by Rooster Teeth Productions on 4–5 February 2017.

ICC Sydney was developed by a consortium comprising AEG Ogden, Lendlease, Capella Capital, and Spotless, with AEG Ogden acting as the venue operator.
