Answer 2

Yes Crow is one of the common bird in entire Australia.

Excerpts from Wikipedia reads -

Crows in the genus Corvus appear to have evolved in central Asia and radiated out into North America, Africa, Europe, and Australia.

The latest evidence appears to point towards an Australasian origin for the early family (Corvidae) though the branch that would produce the modern groups such as jays, magpies and large predominantly black Corvus Crows had left Australasia and were now developing in Asia. Corvus has since re-entered Australia (relatively recently) and produced five species with one recognized sub-species.
