Bird remains ID

I hope this message gets through with attachments. I recently found the remains of a bird in a fairly substantial block of forest south of Moe in Gippsland, VIC. I imagine it was killed or scavenged by an introduced predator – perhaps a fox. I should have added something more to the photograph to help with scale but the pile of feathers indicated a fairly large bird.

Any ideas? An owl or raptor?
