Mordialloc, a bayside residential suburb, is 25 km south-east of central Melbourne. The name's antecedents are a squatting run ‘Moodi Yallo’ (1837), a census taken in 1841 at ‘Moode Yallock’ and Georgiana McCrae's visit to ‘Mordy Yallock’ in 1844. The name is thought to be derived from Aboriginal words meaning (1) creek named Moodi or Marida or (2) meaning ‘near little sea’ or ‘small tidal stream’. The Mordialloc Creek is both tidal and of more than usual width where it enters the bay. In the nineteenth century a sandbar often made the creek mouth a shallow inlet.
