little pied cormorant (Phalacrocorax melanoleucos). The other birds are Australian wood duck (aka maned goose) and radjah shelduck by the pond, and the head of a great white egret at the front.
Yup, plus several chestnut teal scattered around the pond, a pair on the water, a cormorant at the door to a bird box at the end of the jetty, a radjah amongst the trees at the back left, and the white blob in the top left corner is the belly of a pelican.
