GWN7 was an Australian television network serving all of Western Australia outside metropolitan Perth. It launched on 10 March 1967 as BTW-3 in Bunbury. It was an affiliate of the Seven Network and served one of the largest geographic television markets in the world—almost one-third of the continent. The network's name, GWN, is an acronym of Golden West Network, the network's name from 1979 to when the current name was adopted in 2011. In 2021, GWN7's parent company Prime Media Group merged with Seven and the brand was retired in 2022.
