I reported similarly on Fri 21-Feb-20 6:27 PM, to this list, of a White morph GG over my home in Kambah on that day. It appears that they really do know of
their ability to make use of the similarity of appearance to Sulphur-crested Cockatoos and maybe use it to surprise other prey. In Lamington NP in SE Qld, years ago, I have once seen grey morph GG among Topknot Pigeons.

Mark,
had probably the same bird just a couple of days ago (6 Apr) in North Lyneham (quite close to your site), flying with a small flock of Sulphur-crested Cockatoos. It was harassed persistently by 2 A Raven and 2 Magpies.

Morning all,
While I was having a late breakfast a couple of minutes ago the local
magpies and ravens suddenly went berserk over my backyard in Kaleen. A
quick dash to the back deck revealed a white morph Grey Goshawk being
pursued by everything that could fly!! It beat a hasty retreat to the
east. From the size of the bird, small, I would say it was a male.
