The Cockatoo is found in Australia and New Guinea. If you plan to visit Australia you can find them in suburban areas of Adelaide, Melbourne, Canberra, Sydney and Brisbane. However, the perfect spot that I found them on was the Daydream Island off the Whitsundays. While I was very sad to see it rain on the day I was there, it made my day to see this bird come to my balcony.
