The Cheetham and Altona Important Bird Area comprises several wetland sites on, or close to, the north-western coast of Port Phillip in Victoria, south-eastern Australia. Collectively they total 1223 ha in area and lie within, or adjacent to, the western suburbs of the city of Melbourne. They were classified as an Important Bird Area (IBA) because they support more than 1% of the world populations of red-necked stint, chestnut teal and Pacific gull.[1]
