@MichaelBedingfield .. Hi Michael, thanks for the ID .. this is a confusing one for me .. I believe this to be an immature Pied Butcherbird .. it was being fed by an adult but I unfortunately didn't get a good look at the adult bird .. I assumed Grey B but after looking at my bird guide and eBird I thought it resembled more a Pied B .. as I wasn't certain, I posted on the ABID facebook site .. and also iNaturalist .. where Pied was confirmed .. but happy to be corrected.
