The Broome Bird Observatory is an educational, scientific and recreational facility located 24 km from Broome in the Kimberley region of Western Australia. It began operating in 1988 under the auspices of the non-profit organisation Birds Australia to provide a base for the study and enjoyment of the birds of Roebuck Bay and adjoining areas. The bay boasts the highest diversity of migratory waders in Australia. In March and April, immense flocks of waders can be watched as they depart to their breeding grounds in the northern hemisphere.
