... so skink1978 you are probably right (or are there three Birds???)
It would be a first for me if I am correct! Just checked Birdguides and both the Hull bird and the one reported later at Scaling Dam had a little 2nd Winter White-fronted Goose that never left it's side. What are the chances of two different TBG's having the same mate?
