Brimbank Park (coordinates 37.7340° S, 144.8370° E) is located in the Maribyrnong Valley (hollowed by the Maribyrnong River), near the Melbourne suburb Keilor. It is intersected by the Maribynong River and the M80 highway, which reveals the adaptive nature of the natural environment in a growing urban area. (Parks Victoria, 2013)

Brimbank Park consists mainly of sedimentary rock, due to its close proximity to the Maribyrnong River. Along the banks, alluvial deposits and terrace sediments arise from the Quaternary Period (Geological map of Victoria, 1973). Although there is a distinct lack of igneous rock in area, the sediments from primary igneous rock upstream

(Parks Victoria, 2007). Basalt in the area also suggests a once present volcano, whose eruption may have resulted in the creation of the Keilor Plains. (Brimbank City Council, 2012)
The major geographic and topographical features of the park exist due to the Maribynong River. The tributaries of the nearby Maribyrnong River, Jacksons Creeks and Taylors Creek, created deep and very fertile valleys in the basalt plains, leading to a green landscape. (Parks Victoria, 2005).
History, fossils and artefacts indicate the region appealed to human civilisations such as the Aboriginals around 40,000 years ago. The walking paths and surrounding urban development highlights that the park is still a popular place today.

Based on the geology of the area, it is known that there are two main types of soil in Brimbank Park. The park is mainly comprised of a basaltic plain created by previous volcanic activity (Stone, 2004). However, with water flowing around the horseshoe bend in the park, it brings alluvial soil form further upstream and is deposited around the banks of the river. The
