best suggestion is to go to a uni and do a course over 4 years that would cost you around the 50k mark, and then set aside another 35K for flying. I had to do it and most of it was working back home and part time job in aus.
i suggest you thoroughly check out all the flight schools and compare the prices. if smart, you can do your bachelors degree on your student visa, and choose a cheaper flight school (not necessarily one that is authorized to grant you a student visa). and from day one, start working and saving. NO night clubs or pubs
try not to get hold of a sheila to keep ur junior happy. been there done that. only to repent at the end!
all the best, buddy!
