Wattle Grove is a suburb of Sydney, in the state of New South Wales, Australia. Wattle Grove is located 30 kilometres south-west of the Sydney central business district in the local government area of the City of Liverpool.
Wattle Grove is a residential suburb with a small shopping centre and a number of recreational areas such as Wattle Grove Lake, Wattle Grove Park, Lakeside Park and Australis Park.
Wattle Grove was built on former Australian Defence Force land. The original plans for a suburb were made by the government of Prime Minister Gough Whitlam in the 1970s. Infrastructure was built and the suburb lay dormant until further developed by Delfin Property Group, assisted by the Defence Housing Authority in the 1990s. In 1992, the suburbs name was changed from Holsworthy Village to Wattle Grove. On 12 April 1992, Wattle Grove was officially opened by Prime Minister Bob Hawke.
In 2006, Wattle Grove's tree-lined streets underwent significant change. Many of the casuarina trees (Australian Pine) that lined the main road were replaced, due to roots potentially damaging nearby houses or falling during storms. Native shrubs have been planted in their place.
