A friend living in Moruya Heads sent me this photo for ID.
My guess is that it is a newly fledged Satin Bowerbird. I have never seen one so young and none of my books, including HANZAB shows a chick as opposed to a juvenile bird.
You can see some olive green on the upper back and the head/bill shape is characteristic. The dots on the wing are somewhat more prominent than the juvenile.
Interestingly, the bird still displays a gape. So, it may be within 3 weeks of fledging. HANZAB has a detailed description of plumage but I found it difficult to correlate with what I see in the photo.
Can someone more familiar than I verify the ID for me please?
