The introduction of exotic pests into our bays and waterways can adversely affect aquatic habitats, food chains, the ecosystem and our enjoyment of the marine environment.
On these pages you can learn more about invasive marine pests and what you can do to prevent their introduction and spread into Victoria’s unique and economically important marine environment.
The risks posed by marine pests
Some marine pests pose a risk to human health and can affect the valuable economic benefits provided by the marine environment including aquaculture, recreational and commercial fishing, and domestic and international shipping. Once a marine pest becomes established, it is nearly impossible to eradicate and carries a significant threat to our marine biodiversity.
Many exotic aquatic species are already found in Port Phillip Bay, which is a major international port and an entry point for new marine species into Victoria. In recent years, there have also been reports of marine pests outside of Port Phillip including at Apollo Bay Harbour (Undaria), San Remo, Inverloch, Tidal River, Gippsland Lakes (Northern Pacific Seastar), and Western Port (Pacific Oysters).
Preventing the entry of new pests and spread of existing marine pests is a crucial challenge for all responsible government agencies, industry and the community.
