King George Sound

King George Sound is the name of a sound on the south coast of Western Australia. Located at 35°02′S 117°56′E / 35.033°S 117.933°E / -35.033; 117.933, it is the site of the city of Albany. The sound covers an area of 110 square kilometres (42 sq mi) and varies in depth from 10 m (33 ft) to 35 m (115 ft). The sound is bordered by the mainland to the north, by Vancouver Peninsula on the west, and by Bald Head and Flinders Peninsula to the south. Although the sound is open water to the east, the waters are partially protected by Breaksea Island and Michaelmas Island. There are two harbours located within the sound, Princess Royal Harbour and Oyster Harbour. Each receive excellent protection from winds and heavy seas. Princess Royal Harbour was Western Australia's only deep-water port for around 70 years until Fremantle Harbour, south of Perth was opened.
