Admiralty House is the Sydney official residence of the Governor-General of Australia. It is located in the suburb of Kirribilli, on the northern foreshore of Sydney Harbour (adjacent to Kirribilli House, which is the Sydney official residence of the Australian Prime Minister). This large Victorian Regency and Italianate sandstone manor, completed in stages based on designs by James Barnet and Walter Liberty Vernon, occupies the tip of Kirribilli Point. Once known as "Wotonga", it has commanding views across Sydney Harbour to the Sydney Harbour Bridge and the Sydney Opera House.
