Is this an Australian corvine? (1 Viewer)

I spotted this fellow on the wall of a garden in Cottesloe, a coastal suburb of Perth in Australia, but can't be sure of what it is. The most obvious thought is that it is one of the smaller corvines. Perhaps my field guide (Slater) isn't good enough but none of the illustrations match this bird. The distinctions for me are the curved bill and the brownish head. Can anyone suggest what it could be? It would be nice to resolve this mystery! Perhaps it's a juvenile of one of the Australian corvines?
Many thanks

Australian Raven is the common corvid in Perth, so I guess it's a juvenile of one of those. You'll need a local to answer if that can explain the dark eye. It does look rather skraggy in general.

Thanks Larry - your suggestion was what I was thinking. But it's that curved bill that still bugs me! Perhaps it becomes straighter as it becomes an adult? A local birder's opinion would be useful. G.

Immature Australian Raven. Possibly a moulting from juvenile to 1st immature? Juveniles have a duller plumage "Juv smaller and browner, with softer plumage that lacks gloss" (Australian Bird Guide)
If bill is curved it is very slightly so - looks like a normal raven bill to me.

Thanks mjh73. I think with your assessment and that of Larry Sweetland,we've knocked this one on the head! It's clearly a young Australian Raven. Thanks again to all. G.
