The home of the Penrith Panthers currently has a capacity of 21,000 and has been home to the Panthers since 1967, when they earned entrance into the Sydney Premiership.
Traditionally known as Penrith Stadium until naming rights were purchased by Credit Union Australia, the venue also hosts Penrith Napean United, who play football in a league below the A-League.
The record attendance was set on the 7th September 2003 when Penrith took on Parramatta. A record 22,304 squeezed into the stadium despite the capacity of 21,000 for the match and watched the home side win 40-20.
In the World Cup, CUA Stadium will host the Group C game between Tonga and Samoa as well as the 9th place play-off match.
