The Moorabool Yluk (River) flows 160 kilometres from its source in the Wombat Forest near Ballarat and Ballan and joins the Barwon River at Fyansford, Geelong. Moorabool Yluk has great cultural significance for the Wadawurrung/ Wathaurong people. According to the Heritage Centre’s Street names index, Morrobool Yluk ' is generally regarded as meaning the curlew; however, some refers to the supernatural evidenced by the curlew’s weird cry.' This is noted in Place names of Victoria by Les Blake, which defines it as haunt or cry of the curlew." In 2022, the river is the most flow-stressed river in Victoria – in an average year 62% of its water is extracted for use, the highest level of use in the state of Victoria leaving at times reas that look like creeks.

Several Aboriginal names have been recorded for the Lal Lal Falls, including 'Bundjil', and 'Lal Lal', said to mean 'dashing of waters in a crevice' (Clark and Heydon 2002). Aldo Massola (1968:59), described the Kulin 'myth' of the Lal Lal Falls : 'Bundjil made the falls to relieve the monotony of the landscape. He liked them so much that he decided to make them his earthly home'. Massola explains (1968:x) that the accounts 'were collected over a period of ten years, from Aborigines in all parts of Victoria'. Another story is that Bundjil created the waterways in this area and Lal Lal Falls is where he returned before heading to his resting place in the stars continuing to watch over the people and land.
