Lauderdale is a town on the outskirts of Hobart, capital of Tasmania, Australia. The population of Lauderdale is approximately 2,388 (2006 census). It is in the local government area of City of Clarence. The town is situated on the eastern side of a thin Isthmus that connects the South Arm peninsula to the mainland. It faces Ralphs Bay, and the majority of Lauderdale's population live along Roches Beach, which faces Frederick Henry Bay. Along with nearby Seven Mile Beach, it is a popular residential area for people working in the Hobart CBD.
Lauderdale/Roches Beach is overlooked by Single Hill, which is just to the North. Beyond Single Hill is the town of Seven Mile Beach The view from Single Hill gives a clear view of the town of Lauderdale.
The view also shows the nearby ABC radio transmitter mast. The Ralph's bay side of Lauderdale reveals a sharp gradient in the bay where the water changes colour. This change can be especially noticeable when driving along the main road from Hobart. Walker Corporation had plans to build a large residential 'canal estate' in Ralphs Bay in front of Lauderdale. Therewere many protests against the development on ecological grounds; the development would be over sensitive mud flats and affect the habitat of migratory birds and the endangered spotted handfish. Former State Premier Paul Lennon was very much in favour of the development whilst acting as premier. He has close relations with Walker Corp. In June 2010, Ralphs Bay was saved when the Tasmanian Planning Commission rejected the proposed 'Lauderdale Quay' canal housing development.
