Seagrass Sled in action underwater

Can you help us with this underwater survey?

We need volunteers with a boat and time to tow our seagrass sled and make recordings of the seafloor over the next 3 months.

Tin Can Inlet Location & Significance

Tin Can Inlet is part of the larger Tin Can Bay which is located on the Cooloola Coast of Queensland adjacent to the towns of Tin Can Bay, Cooloola Cove and Rainbow Beach. It is part of

Habitat Values

Tin Can Inlet has extensive inshore seagrass meadows and intertidal flats. The upper inlet contains brackish waters associated with wallum heath. There are extensive mangrove zones and saltmarsh along estuary with Avicennia, Ceriops and Aegialitis recorded and it is the southern distributional limit of mangrove species Aegialitis annulata, Xylocarpus granatum and Osbornia octodonta. Mosaics of mangrove, seagrass and coral reefs provide habitat for high diversity of fish. The Inlet is the habitat for dugong; coral reefs in the area support scribbled angelfish Chaetodontoplus duboulayi and Müllers butterflyfish Chelmon mulleri at the southern end of their range; and areas of hard and soft coral. (Source Queensland Department of Environment and Science 2021).

The mooring problem

Underwater research conducted by Cooloola Coastcare in 2017 -18 and 19 indicates that Tin Can Inlet is at crisis point for biodiversity loss and sediment impact. Evidence shows that the block and tackle moorings and sediment runoff are contributing factors. Without a concerted effort on multiple fronts including mooring replacement with seagrass friendly alternatives and weed and erosion control on the foreshore, Tin Can Inlet risks habitat collapse which will further impact the ecosystem and the tourism and fishing industries that rely on the Inlet . This could impact land values in the future and affects quality of life of the residents and enjoyment of the area by visitors.


What can Cooloola Coastcare do?

The overall aim is to engage the stakeholders and government organisations with jurisdiction over Tin Can Inlet, the moorings and the surrounding areas to develop a 10 year plan to rehabilitate Tin Can Inlet to a healthy ecosystem with thriving marine life and a healthy natural foreshore for the enjoyment of local residents and visitors as well as the sustainable use by commercial entities that make their living in the area. Through 'Collective Impact' we can all work towards a future in which Tin Can Inlet is a healthy, thriving ecosystem capable of sustainable use for pleasure and commerce.

Part of a bigger picture

Sustainable Development Goal 14 of the United Nations aims to “conserve and sustainably use the oceans, seas and marine resources for sustainable development”. Achieving this goal will require rebuilding the marine life-support systems that deliver the many benefits that society receives from a healthy ocean.

Some species of marine turtle and all dugongs depend on seagrass for food. Many marine creatures that don't eat seagrass depend on the habitat it creates for their food.

Reports and Plans

What's Next? Stage 2

Application has been made to the Gympie Regional Council Environment Grants to fund the following activities.

  • A Seagrass Survey to prioritise the 9 mooring fields. This includes the construction of a 'seagrass sled' to carry underwater cameras.

  • Mooring Owners Town Hall Meeting & 1:1 meetings.

  • Construction of Static Displays of Environmentally Friendly Mooring Models for display in the community and use at meetings.

  • Historical Research into seagrass and fishing in Tin Can Inlet.
