The gobiid, Acentrogobius pflaumii, was recorded in Cockburn Sound in southwestern Australia in 2004, and is now reported for the first time from the Swan River Estuary ca. 20 km north of the initial collection site. It was observed by SCUBA divers on open, soft/silt substrata and was abundant in areas of the middle Swan River Estuary. Ballast water emissions from a nearby international port, containing eggs and/or fish, are considered the most likely introductory vector. Although the ichthyofauna of the Swan River Estuary has been frequently surveyed, it is difficult to speculate how long A. pflaumii has occurred in southwestern Australia because most surveys have not targeted small, cryptic species. The population increase and spread of A. pflaumii in eastern Australia and New Zealand infer that further range expansions in southwestern Australia are likely.
