pilotads,
Don't fly for free. just don't.
Time to start doing your research. Find out the areas around Oz that do scenics or farm work. They usually take on low houred pilots. I got my start in Kununurra. Others have got starts in Halls Creek, Broome, Karumba and the like.
In other words, you've got to find where the work is, and go there.
Typically you'll need about 1000 hours before you'll be let loose on the twins. Go bush and get the single time.
