Pumicestone Passage is a 35-kilometer-long coastal estuary separating Bribie Island from the mainland, stretching from Caloundra in the north to Deception Bay. It is a narrow, winding, and shallow waterway that is part of the Ramsar-listed Moreton Bay Marine Park. The passage is known for its significant tidal influence, with some areas drying out completely at low tide, making tide timing a critical safety and planning consideration for paddlers. The water is generally sheltered and mangrove-fringed, providing a scenic aquatic playground popular for kayaking, paddle boarding, and canoeing. Key access points for launching include Golden Beach on the mainland and the Toorbul Boat Ramp, which provides straightforward access to the passage. A popular paddling route is the loop from Golden Beach across to Bribie Island. The area is a declared fish habitat area and a high-value waterway, home to a rich diversity of wildlife including dolphins, dugongs, turtles, and hundreds of species of birds, including migratory shorebirds. While the passage attracts boat traffic, its sheltered nature generally limits large wave fetch, though paddlers should be mindful of channel crossings and other vessels. The environmental health of the passage is managed under a catchment action plan due to concerns about declining water quality and habitat loss, though it remains a regionally significant ecological and recreational asset.
