Our Catchment

Cooloola Coast – Southern Great Sandy Strait Catchment 

The Cooloola Coast – Great Southern Sandy Strait Catchment is quite unique, and posed a number of challenges at the time of Queensland Catchment boundary mapping in the early part of 2000.Situated at the northern end of Great Sandy Cooloola National Park (Northern Section) and southern end of World Heritage Fraser Island and including the Great Sandy Marine Park, the Cooloola Coast draws water from the upper Noosa River and underground acquifers of the Cooloola sandmass.

Thus our water is drawn from the South East Queensland Catchment area (SEQ Catchments).The coastal creeks form in the hills to the west and north west of the townships of Rainbow Beach, Tin Can Bay and Cooloola Cove, flowing overland and underground to the wetlands and tidal estuarine areas of the Great Sandy Strait.

A dominant freshwater influence on the catchment, especially the marine ecology however, is the Mary River. The mouth of the Mary opens at the northern end of the Great Sandy Strait, where strong currents and fresh water flows influence the Strait to Hervey Bay in the north and Inskip Point and Tin Can Inlet to the south.

The Cooloola Coast has therefore been included as the southern most coastal extremity of the Burnett Mary Catchment Region (Blue area of map on right); but is officially known as the Noosa Basin (north) by the Qld Dept of Environmental and Heritage Protection. http://wetlandinfo.derm.qld.gov.au/wetlands/MappingFandD/WetlandMapsAndData/SummaryInfo/B-140.jsp

Map courtesy of DERM on right (Proposed extension to Fraser Island World Heritage Area, March 2010) shows the Cooloola Coast- Southern Great Sandy Catchment area of interest for Cooloola Coastcare Association Inc. It includes the coastal creeks, acquifers, wetlands, marine and dune areas, as well as the coastal towns of Tin Can Bay, Cooloola Cove and Rainbow Beach. Partnerships include the key stakeholders: SEWPaC, EPH, DEEDI, GRC, BMRG, QPWS and Wide Bay Military Reserve.
