Summary The IBA includes high-tide roosts and low-tide feeding areas for more than 1% of the world's Great Knots.

Site description This IBA is a stretch of muddy and sandy coast just east of Darwin, from the shorebird roost at Lee Point to the end of the muddy bay at Tree Point. The northern extent of the boundary is poorly defined and could extend to the northern boundary of the Shoal Bay Conservation Area or to Gunn Point (the end of the bay); this requires more fieldwork. The IBA extends inland to include the mangroves but not the terrestrial vegetation.
