Protect Victoria’s coast this summer

2 January 2026

As more people head to Victoria’s bays and coastlines over summer, Agriculture Victoria is reminding everyone on the water to help stop the spread of marine pests.

Marine pests are invasive, non-native plants and animals that can damage aquatic habitats, disrupt food chains and affect how Victorians enjoy the coast.

Agriculture Victoria Biosecurity Executive Director Charlotte Austin said simple actions before and after each trip on the water can make a real difference.

‘Boats, trailers and recreational equipment can unintentionally move marine pests from one bay or waterway to another,’ Ms Austin said.

‘By taking a few extra minutes to Check, Clean and Dry, people can help protect Victoria’s marine environment for future generations.’

Marine pests can be very small, such as algae, or more obvious, including sea stars, seaweed, mussels, barnacles, sea squirts, crabs and fish. They often hide in hard-to-see places like anchor wells, propellers, hull surfaces, trailers, water inlets and fishing gear.

Everyone spending time on the water with boats or other equipment is encouraged to remember:

• Check boats and equipment for any attached plants or animals and remove them. Do not return marine pests to the water.
• Clean vessels, trailers and gear with freshwater after use.
• Dry everything thoroughly before moving to a new location.

Ms Austin said keeping an eye out for anything unusual in the water is also important.

‘Early reporting helps stop new pests from being introduced and prevents existing pests from spreading along our coastline,’ she said.

This summer, Victorians can learn more about marine environments and how to protect them through free, family-friendly activities.

Bookings are now open for more than 100 free activities as part of the Summer by the Sea program, running from 3 to 18 January along Victoria’s coastline.

Agriculture Victoria will host 2 marine pest information and snorkelling sessions at Frankston Pier at 10 am and 1 pm on 14 January, helping participants identify marine pests and learn how to stop their spread.

If you spot something unusual in the water, report it to Agriculture Victoria.
