A huge tract of land at the northern end of the island is protected national parkland. The national park blankets roughly a third of the island, or 55 square kilometres. Bribie Island’s national park is accessible only by 4WD along the beach heading north just a short distance from Woorim surf beach. The national park is a popular spot for four-wheel driving, fishing and camping.
The Pumicestone Passage Marine Park is also protected as an environmentally significant wetland of international standing. It is protected by several international treaties, including the RAMSAR convention. The Passage is a narrow, tidal stretch of water separating the mainland from the Island.
The Passage connects to the sea at each end of the island. It is a haven for endangered migratory birds and marine mammals, including dugongs and dolphins. If you are lucky, dolphins can be spotted from the shore leaping out of the water and frolicking in the sheltered waters of the Pumicestone Passage. Visitors looking to spot wildlife can also hire a jetski or jump aboard a Bribie Island Ferryman cruise. Those on the Passage are expected to take precautions to protect the endangered dugong population, including travelling at slow speed over seagrass beds, observing Go Slow zones at Tripcony Bight, Long Island and Westaways Creek, using bait-disposal bags and safely disposing of plastic and other foreign objects.
