The Sydney Olympic Park Aquatic Centre (SOPAC) , previously Sydney International Aquatic Centre (SIAC), is a swimming venue located in the Sydney Olympic Park in Sydney, New South Wales, Australia. Built in 1994, the SOPAC was a major venue for the 2000 Summer Olympics as it hosted the swimming, diving, synchronized swimming, the medal events for water polo, and the swimming portion of the modern pentathlon competitions. The SOPAC has since been a host venue for numerous schools and swimming associations around New South Wales. Currently, it has most notably been the venue for the annual CAS Swimming Championships. The SOPAC also includes a swim shop at the entry of the arena, a play area, a health club and operates swimming classes for all ages.
The arena currently holds 10,000 people. Capacity was boosted to 17,000 during the 2000 Summer Olympics. The venue is currently temporarily closed due to Sydney's current COVID-19 outbreak.
