It depends on a lot of factors:
1)Where you are flying?
2)What kind of operations?
3)The company you are flying with!
But I can say, roughly it might be somewhere between 20AUD - 50 AUD an hour or a fixed pay of maybe 3000 AUD and regarding the total number of hours, it again depends, if you are on full time employment, then somewhere between 60-100 hours.
Hope this helps
