Coochiemudlo Island Shoreline Erosion Management Plan

Share on Facebook Share on Twitter Share on Linkedin Email this link

Coochiemudlo Island (Goochie Mudlo) is located off the coast of south-east Queensland in the southern part of Moreton Bay (Quandamooka).

With an emerald fringe of native plants and trees, caves, and beaches, Coochiemudlo Island and surrounding waters are home to an array of wildlife, including migratory shorebirds, dugongs, turtles, dolphins and soldier crabs.

Parts of this small, sub-tropical island, however, are subject to coastal erosion brought on by weather events and storm tide inundation.

Redland City Council, with input from the Community Reference Group (CRG) and other stakeholder groups, is developing a comprehensive plan known as a Shoreline Erosion Management Plan (SEMP) to identify the island's erosion hot-spots and recommend the most suitable management options to help protect the island from coastal erosion.

What is the Community Reference Group?

The SEMP's CRG represents a cross-section of the island community and includes representatives from Quandamooka Yoolooburrabee Aboriginal Corporation. The CRG has been involved in developing the SEMP since 2017.

The CRG brings together Traditional Owners and local stakeholders to contribute their local knowledge of erosion, as well as the wider cultural, historical, environmental, and economic values of the island.

This group will also contribute by sharing information, insights, and progress reports back to their community networks.

Everyone can get involved

Share your photos of Coochiemudlo Island's erosion hot-spots, including any historic images you have, or shots you took after big storms or other weather events.

Simply click or tap on the map of the island, find the erosion hot-spot on the map, and add a pin to upload your photos. You can even write some words describing the erosion you have seen there.

    More than 40 locals and mainlanders turned up for the Open House and many stayed to read and absorb the information on Coochie's coastline and ask our experts questions. People identified key areas of value from an economic, social and environmental standpoint and these comments will be passed back to the consultants for consideration in the SEMP development.

  • Open House Information Session

    Come along to our Open House information session at the Coochie Island Rec Club on Saturday 13 October between 9am-3pm to get the latest on the Coochie Island SEMP.

    Coochie’s foreshore has changed over time and the Coochiemudlo Island Shoreline Erosion Management Plan (SEMP) is now under development in response to current erosion processes.

    So, put the date in your diary and join the experts at the Open House for an update on Coochie’s coastline and the coastal forces changing it. Your representatives on the Coochie SEMP Community Reference Group will be there with coastal experts from within and outside Council to help you understand the processes.

    We’d also like to hear from you on what you value most about Coochie.

    Consultants BMT were commissioned in July 2018 to work with Council to deliver the Coochie SEMP and have recently made a presentation to the Coochie SEMP CRG.


  • Bathymetric Survey

    In June 2017, Redland City Council commissioned a bathymetric survey of the shoreline of Coochiemudlo Island. The survey helps us understand the underlying topography of Coochie's coast and how this may influence wave action, currents and transportation of sediment around the island.



  • Coastal Adaptation

    An increase in the severity of natural hazards on coastal areas has prompted the State Department of Environment and Science to provide funding to coastal Councils such as Redland City Council, to develop Coastal Hazards Adaptation Strategies (CHAS) under the QCoast2100 Program.

    This is a whole-of-City strategy that considers existing and emerging hazards, their associated risks and the best management of those hazards.

    The Coochiemudlo Island SEMP fits within this framework but looks more specifically at the particular impacts on Coochie's coastline.

    This is important because, while erosion of shorelines has been occurring for many years, it has the potential to impact on social, economic, environmental and cultural values of the place.

    Any SEMP needs to consider the risks, including the effectiveness of proposed and existing works, and ensure there is no increase to coastal hazard risk for adjacent areas.
