The Anglican Diocese of Perth is one of the 23 dioceses of the Anglican Church of Australia. The constitution of the Diocese of Perth was passed and adopted in 1872 at the first synod held in Western Australia. In 1914, the Province of Western Australia was created and the diocesan bishop became ex officio metropolitan bishop of the new province and therefore also an archbishop. The diocese incorporates the southern part of the state of Western Australia and includes the Christmas and Cocos Islands.
