In Australia, the introduced northern Pacific seastar (Asterias amurensis) was first recorded in southeast Tasmania in 1986, where it has become the dominant invertebrate predator in the Derwent River Estuary. Manual removal of seastars has been attempted on aquaculture farms, around oyster racks and grow-up trays, and in the intertidal using dip nets or poles with a long nail on the end to spike the seastars (McEnnulty, Dredging is unlikely to have a significant impact on the, Trapping has resulted in limited success. The maximum temperature for A. amurensis is 25°C and the minimum is 0°C (NIMPIS, 2002). Northern Pacific sea stars live in estuarine, intertidal, and coastal zones and prey on other marine inhabitants in or on the substrate. The main threats to the species are in competition, displacement and possibly predation from introduced seastars such as the New Zealand Seastar and the Northern Pacific Seastar, and The ships suck in the ballast water containing seastar larvae in a port in Japan for example, and let it out in a port in Tasmania. and is not a nuisance but seen more for beauty. The seastar is also considered a mariculture pest, settling on scallop longlines, spat bags, mussel and oyster lines and salmon cages (CSIRO, 2004).

The Northern Pacific Sea star is causing great issues in not only Wilsons Promontory but around Australia today. The seastar is considered a serious pest of native marine organisms. Free-swimming larvae of the seastar found their way into the ballast waters and since introduction, the species has massively thrown off the trophic web in the reef ecosystem. Not all the marine life residing in Port Phillip Bay is good for the environment and the Northern Pacific Seastar is a good example of how one species can do much to damage the native marine environment. The tips are distinctive. http://www.marine.csiro.au/crimp/reports/PriorityPestsFinalreport.pdf, Hewitt C. L, L.

Like other species of sea stars, they can re-grow missing limbs, which makes them very difficult to kill. Introduced Marine pests, National Control Plan for Northern Pacific Seastar, Implementation Workshop May 2002. Asterias amurensis general information. Hunting incentives have been suggested, such as catching and drying as souvenirs of the Australian coast (Goggin, 1999). It is typically found in shallow waters of protected coasts and is not found on reefs or in areas with high wave action. Echinoderm means spiny skin—a reference to their hard, calcified skin, which helps to protect them from predators. However, the tropical-temperate waters surrounding the continent of Australia and the cold-temperate waters of the Northern Pacific Ocean also have their fair share of the starfish population.

Starfish use filtered sea water to pump nutrients through their nervous system. It is found in the Derwent Estuary (Hobart), Tasmania and Port Phillip Bay, Victoria. It is often found in estuaries and on mud, sand or rocky sheltered areas of intertidal zones (CSIRO, 2004). While A. amurensis (northern Pacific seastar) prefers waters temperatures of 7-10°C, it has adapted to warmer Australian waters of 22°C.
