Government House is located on St Georges Terrace (Perth's main thoroughfare), sitting on the same block as Council House and the Supreme Court buildings. The site has been used by governors since the establishment of the Swan River Colony in 1829; the current building is the third to have served that purpose on the site. The buildings and gardens of Government House are of exceptional heritage significance, being listed on the Western Australian Register of Heritage Places and classified by the National Trust. They are regularly opened for public viewing.
