Originally described from Fiji, and recorded from Japan to Australia. It is a warmer water species, and the record from South Australia is from a power station thermal waste water plume, and it is likely to be an accidental introduction there via shipping. Recent records from Lake Illawarra, NSW, are also likely to an accidental introduction.
