Water quality
Melbourne Water rates the condition of the creek as “very bad”. According to the agency, Koonung Creek is the most polluted flowing water in Melbourne. The measuring station in Bulleen registered an average infestation with E. coli bacteria of 1800; this is nine times what is permissible for a body of water suitable for swimming and also the highest concentration measured in a flowing water in Melbourne. Koonung Creek has been in this poor condition since the beginning of European settlement.
Still, five types of frogs can be found in the stream (Common Eastern Froglet, Spotted Marsh Frog, Striped Marsh Frog, Eastern Banjo Frog, and Brown Tree Frog).
