Australia has been broadcasting the Eurovision Song Contest 12 4, 4:19pm

Member countries within the EBU boundaries are eligible to participate.
This is why Israel can compete and why Morocco competed once.

Australia is technically not in the boundaries, but has associate member status.

And I believe that Australia is too far away from most of the participating countries to host. Oh, and jet lag.
