I'm just guessing it's the Australian Ibis based on location, it may be another kind, I'll try to get a better photo. There is flocks of these around my local rubbish dump.

Know it's an Ibis. I can't find the correct species.
The family Threskiornithidae includes 34 species of large wading birds. The family has been traditionally classified into two subfamilies, the ibises and the spoonbills; however recent genetic studies are casting doubt on the arrangement, and revealing the spoonbills to be nested within the old world ibises, and the new world ibises as an early offshoot.
