In Victoria it was originally collected at Corio Bay and Coode Island near the mouth of the Yarra River between 1901 and 1911, and was presumed extinct until rediscovered at Port Melbourne in 2010, where found in weed dominated 'wasteland'. Probably introduced at both sites through shipping from South Africa
