Pumicestone Passage is a 35-kilometer-long ecological marvel and a premier saltwater fishing destination, forming a sheltered, winding waterway between the mainland and Bribie Island. As part of the Moreton Bay Marine Park and a declared Fish Habitat Area, it is a critical nursery for numerous species, supporting both tropical and temperate marine life. The passage is notably shallow and narrow, with extensive areas that can dry out completely at low tide, demanding careful navigation. Its ecosystem is defined by a rich mosaic of habitats, including all seven of Moreton Bay's mangrove species, patchy seagrass beds, saltmarsh areas, extensive mudflats, and shoals. This diversity of structure, combined with its status as a Ramsar-listed wetland, creates a prolific and protected fishing environment that is a cornerstone of the region's recreational fishery.
