Q: What can a Commercial Helicopter Pilot Licence holder expect to earn?

I have a number of options for the use of a recent inheritance, one of which
is to fullfil a lifetime desire to fly choppers.
What could a Helicopter Pilot expect to earn, flying in Australia?

I realise this may be a little like asking, "How long is a piece of string?"
(A: twice as long as half it's length) but there must be some ballpark
figures available.

Any help you can provide will be greatly appreciated.

Thanks in advance
