Mount Annan, a suburb located southwest of Sydney in the Camden Council area, has a history deeply rooted in both indigenous culture and European settlement. Originally home to the Dharawal people, the area also saw the presence of the Darug people from Western Sydney and the Gandangara people from the Southern Highlands.

In terms of European development, Mount Annan has evolved significantly over the years. It encompasses the locality formerly known as Glenlee and the site of the Glenlee Colliery loader, which served the coal mines of the Burragorang Valley. The area has seen various land releases aimed at different homebuyers, contributing to the growth and diversity of the community.

Mount Annan is known for its educational facilities, with several local schools serving the community. Mount Annan Public School, Mount Annan High School, and Mount Annan Christian College are notable institutions in the area. The suburb also has a range of sports clubs and facilities, including the Mount Annan Leisure Centre, which boasts a variety of amenities.

One of the most significant landmarks in Mount Annan is the Australian Botanic Garden. Opened in 1988, this native plant garden and arboretum were developed on what was once a dairy farm. The Botanic Garden is renowned for its collection of native plants and its role in conservation and research, including the preservation of the endangered Wollemi Pine. The garden is not only a hub for botanical research but also a recreational space for the community, featuring various themed gardens, outdoor sculptures, walking tracks, picnic facilities, and educational services.
