Large bird spotted in the top of a tall tree, from quite a distance away. Similar in shape and I think size to a Currawong. White and various shades of grey on the back, white with black striations on the belly. Tail has white tips.
Thanks Jackie. Perhaps the lighting is making it difficult. I thought it quite a bit larger than an Oriole as well but I am no expert. We have certainly had a lot of Orioles around this year.
