Never taken pics of either bird before, possibly it's something else entirely! At the time, through the VF I thought I was looking at a boobook because that's basically the only bird like it I've seen this close to metro brisbane, but after cleaning a lot of interposing branches in post, it doesn't really look much like that.

Thanks for any help. Location was approx here:
I think it is a young Brown Goshawk rather than a Collared Sparrowhawk... beetle-brow, lack of overly long middle toe and stout legs. Feel free to try Australian Bird ID on Facebook as the experts reside there... remember to include where you saw the bird. Great photos!
I agree with juvenile Brown Goshawk.
Nice shots!
