Hi @Mike. I suggested Zanda funerea (64% confidence) based on all images in this sighting. If you disagree, please help me improve by verifying the correct species.
I would politely and definitely say they are Noisy miners (Manorina melanocephala) with a ?Currawong flying past. Look at the third image which shows the grey plumage on the body, the short, sharp yellow beak and that distinctive mask around the eyes. I hate them!
