Is a mostly perennial creek rising on the Darling Causeway about 2.5km north west of Bell. It flows generally south west for about 3.5km into Dargans Creek. The early explorers mistook the Koala for some type of Monkey, hence the name. Another possibility for this name is that it was given by timber cutters, who referred to Eucalyptus cypellocarpaas Monkey Gum. This species was prevalent in the creek that bears this name.
