Port Phillip Bay (PPB) is a large (1,930 km2), temperate embayment in southern Victoria, Australia. Extensive bay-wide surveys of PPB have occurred since 1840. In 1995/1996 the Commonwealth Scientific and Industrial Research Organization (CSIRO) Centre for Research on Introduced Marine Pests (CRIMP) undertook an intensive evaluation of the region with the aims of developing a comprehensive species list of native and introduced biota and contrasting previous bay-wide assessments with a current field survey in order to detect new incursions and discern alterations to native communities. Two methods were used to meet these aims: a re-evaluation of regional museum collections and published research in PPB to identify and determine the timing of introductions; and field surveys for benthic (infauna, epifauna and encrusting) organisms between September 1995 to March 1996. One hundred and sixty introduced (99) and cryptogenic (61) species were identified representing over 13% of the recorded species of PPB. As expected, the majority of these are concentrated around the shipping ports of Geelong and Melbourne. Invasions within PPB appear to be increasing, possibly due to an increase in modern shipping traffic and an increase in aquaculture (historically associated with incidental introductions); however the records of extensive biological surveys suggest that this may, in part, be an artefact of sampling effort. In contrast to Northern Hemisphere studies, PPB (and Southern Hemisphere introductions in general) have significantly different suites of successfully invading taxa. PPB is presented as one of the most invaded marine ecosystems in the Southern Hemisphere.

The direct physical, chemical and biotic impacts on Australian coastal waters due to recreational boating (2011, background): “To date, attempts to eradicate these species have failed and by 1998 A. amurensis had extended its range to Port Phillip Bay (Victoria), a large temperate embayment that Hewitt et al. (2004) suggested had more alien species than any other marine ecosystem in Australia.”

Biogeographic partitioning and host specialization among foraminiferan dinoflagellate symbionts (Symbiodinium; Dinophyta) (2004, background): “It is more probable that the recent dispersal of symbionts or their foraminiferan hosts by birds or with water ballast (Proctor and Malone 1965; Hewitt et al. 2004) is responsible for this finding.”
Introduced and cryptogenic marine and estuarine species of South Africa (2011, background): “We tentatively accept the designation of Hewitt et al. (2004) that this alga has been introduced from the Mediterranean to the southern hemisphere.”
A review and synthesis on the systematics and evolution of jellyfish blooms: advantageous aggregations and adaptive assemblages (2008, background): “…of Port Jackson, Sydney (von Lendenfeld, 1887), suggests that it is native to eastern Australia, although this is not beyond question because ship traffic beginning in the early 1800s connected tropical Indo-West Pacific nations, where P. punctata also occurs, to Australia (Hewitt et al., 2004).”
Impacts of introduced seaweeds (2007, background): “…investment in enhanced marine biosecurity delivery in the 2004/05 budget, leading to an increase in marine biosecurity expenditure of almost 300% to ;NZ$ 6.9 million year-1 (;US$ 4.8 million year-1), representing ;4% of total biosecurity expenditure (Hewitt and Bauckham 2004, Hewitt et al. 2004b).”
Recreational boating: a large unregulated vector transporting marine invasive species (2011, background): “This species is native to the western North Atlantic, but the introduction vector is uncertain with hull fouling, oyster translocations and possibly ballast water having been suggested (Cohen & Carlton, 1995; Hewitt et al., 2004).”
Alien species and other notable records from a rapid assessment survey of marinas on the south coast of England (2006, methodology): “…an established method for the synoptic survey of biodiversity in ports, harbours and marinas and the detection of newly arrived nonnative species (e.g. Cohen et al., 1998, 2001, 2005; Coles et al., 1999; Lambert & Lambert, 1998, 2003; Boyd et al., 2002; Hewitt et al., 2004; Pederson et al., 2005).”
