The Little Raven (Corvus mellori) is the default raven (or as most people would call them 'crow') in Melbourne. You have to got further North and West in Australia to start getting true crows.
That being said, the identification of this bird is still not as easy as it seems as we also get Australian Ravens in parts of Victoria. Based on the behaviour of this bird, which included wing flicks after calling, I almost confident of my ID!
I love the range of expressions these birds (or possibly this bird!) seem to have as they were looking for food. The picture were taken a few weeks ago in a local park.
