The gallery is northeast of Parliament House. It is near the High Court and the National Library. There are three levels of galleries. On the main floor, the galleries are large, and are used to display the collections of Indigenous Australian, European and American art. The lower level also contains a series of large galleries, used to display the Asian art collection. The topmost level contains a series of smaller galleries, which holds the gallery's collection of Australian art. A smaller building on the eastern side of the gallery holds the gallery's temporary exhibitions. It includes a sculpture garden. A major expansion of the gallery began in 2006. It included several new galleries for indigenous Australian art.
