Brenan Park is a urban park situated in the western suburbs of Sydney, New South Wales, Australia. Primarily categorised as a sports field, the reserve contains an open grassland, bushland and recreational areas within the vicinity of native plants, such as eucalyptus trees. It is named after John Ryan Brenan, who founded the suburb of Smithfield in 1836. Artificially terraced, Brenan Park was established in the early 1980s and it is one of the largest reserves in the City of Fairfield, and one of the largest non-golf course green spaces in the Western Sydney region. History The shape of Brenan Park appears on the first survey design, in 1838, of the market town sketched for John Ryan Brenan. Brenan Park was planned to be a housing subdivision and a market area in 1938, with its triangular shape fashioned to take advantage of the topography and views of the surrounding district. The housing subdivision was never constructed. The site was used as a sewage disposal depot and landfill until 1980, where it was proclaimed as unhealthy building land in 1981. Subsequently, it was re-landscaped and eventually developed into a reserve. Geography The reserve is located in the suburb of Smithfield, and is bordered by Cumberland Highway, Brenan and Bourke Streets, which all give good passive surveillance opportunities from close residences and contiguous roads. The park's surrounds are mainly single-story houses. Brenan Park is in an elevated and weather-exposed location, with the highest areas being and those near the Cumberland Highway at . The elevated regions in the park are situated alongside Bourke Street, where they would provide a panoramic view of the greater western Sydney area and even the Sydney central business district. Ecology Indigenous trees and shrubs are abundant in the park, with dominant vegetation species being Melaleuca quinquenervia (near the tennis courts), Eucalyptus moluccana (near the car park in Brenan Street), Casuarina glauca, Callistemon viminalis, Paperbark, Acacia, Lomandra and Eucalyptus bosistoana, most of which have large canopies that provide shade. The boundary along the top part of Bourke Street and near Cumberland Highway is thickly planted with an avenue of trees and shrubs, which provide a sense of entry to the park. The park is predominantly made up of sod and it lies on residual soils that are deep. Its trees represent a link to the Cumberland Plain Woodland that covered most of Fairfield local government area before European
