An internationally significant habitat for many birds, the Mud Islands represent a great spot for birdwatching and up to 70 species have been recorded. Listed as a RAMSAR site, which is an intergovernmental treaty for the conservation of wetlands, visiting the island is a unique experience that connects you with a spectacular insight into one of the Bay’s big secrets.

Explore the undiscovered features of the birdlife and be inspired by the gannets, terns, cormorants, silver gulls and pelicans. The month of March is a real feature as flocks of birds gather and it is a particular attraction to bird watchers and wildlife photographers. 

Our tours to these sensitive internationally-recognised environments are ethically-minded and are intentionally shorter length, as we seek to ensure the absolute least impact to the unique habitats whilst providing an opportunity to appreciate the wildlife in a suitable manner. 

Visit a new world of life and movement on this fun boat and guided walking tour from the pretty seaside town of Sorrento, near Melbourne.

Can anyone join?
Yes, it’s ideal for bird watching enthusiasts as much as it is for bushwalkers, naturalists, photographers and anyone unfamiliar with this hidden secret of Port Phillip Bay. All you need is a healthy sense of adventure and being prepared to potentially get your feet wet as you step from the boat to shore.

Will I get seasick?
Our Rigid Inflatable Boats are the same as the ones the Navy, Search and Rescue, Water Police, Fisheries and Coastguard operators use around the world. We call them the rally cars of the sea because of the sure-footed, stable and capable handling they have in all kinds of conditions.

Seasickness does not happen often on a RIB boat, they are open so you feel the fresh air, and the boat sits close to the water surface. If you’re worried about seasickness, we recommend talking with your local pharmacist or doctor about the various remedies available and follow their advice for taking precautions.


Featured Bird Life on Tour

Mud Islands displays all of the characteristics of bird colony ecosystems. However, the islands are unique in several ways. In particular, the proximity to large human populations has facilitated the growth of huge populations of commensal birds such as gulls and ibis. This has intensified the bird-dominated ecological processes to extreme levels. The central lagoon is visited by thousands on intercontinental waders in the warmer months. Mud Islands are a haven for many species of shorebird, and remain the spectacular natural wonder of Port Phillip Bay. 

Species to look for:

  • Silver Gull
  • Straw-necked Ibis
  • Australian White Ibis
  • White-faced Storm-Petrel
  • Australian Pelican
  • Crested Tern
  • Caspian Tern

World Leading Conservation Port Phillip Heads Marine Park

The State of Victoria became a world leader in marine conservation when, after 11 years of investigation, community consultation and debate, it established a system of highly-protected marine national parks and sanctuaries in June 2002. 

Marine national parks are highly protected areas that conserve unique marine habitats in their natural state, and provide an insurance policy against environmental impacts. Victoria’s marine areas include rocky reefs, sponge gardens, towering kelp forests, sandy seafloors, seagrass meadows, mangroves and saltmarsh.

Port Phillip Heads Marine Park network is highly protected and reserved for conservation and protection of marine biodiversity and natural processes, maintenance of scientific reference areas and the opportunity to observe Nature in its true form. It provides a core example and the combination of outstanding natural, cultural and recreational values.
