Western Sydney Stadium, commercially known as CommBank Stadium, is a multi-purpose rectangular stadium in Parramatta, within the Greater Western Sydney region, approximately 24 km (15 mi) west of Sydney CBD. It replaced the demolished Parramatta Stadium (1986) which in turn was built on the site of the old Cumberland Oval, home ground to the Parramatta Eels since 1947. The current stadium opened in April 2019 and has a 30,000-seat capacity. The stadium is owned by the NSW Government and built at a cost of $300 million. The stadium hosts games across the major rectangular field sports in Sydney.
