Carlingford is a Sydney suburb located about 22 kilometres north-west of the CBD in the local government areas of the Hills Shire.
Once upon a time, Carlingford was called Mobbs Hill, not a romantic name as it was derived from the name of the ex-convict settler William Mobbs. However, Mr. Mobbs is credited for bringing oranges to Australia, so, perhaps, it is not so bad. The name Carlingford came about in 1886 after a vote by the residents. This name was suggested by Frederick Cox after he overheard someone describe similarities between Mobbs Hill and the town of Carlingford, Ireland. The area was first settled in the mid-1800s and, for a long time remained as agricultural land on the outskirts of Sydney. Thanks to Mr. Mobbs, it was a significant orange-growing area for the city.
When Sydney expanded, following the end of World War II, Carlingford was rapidly urbanized. More recently, in the 1990s, the government policy of urban consolidation has brought about high-density units and apartments around the town centre and the train station. There have also been significant redevelopments of old houses into medium-density townhouses.
