More than one quarter of the new park stretches across Yantabulla Swamp, which is recognised as an Important Bird Area, based on criteria used by BirdLife International. Yantabulla Swamp hosts thousands of internationally protected migratory shorebirds as well as up to 50,000 waterbirds including threatened freckled ducks, pink-eared ducks, grey teals, night herons and many other species.
