gday Anna, welcome..
the best advice i can give you is dont take crap... aviation is a fun and rewarding career path.
Your best bet would be to go out to bankstown and candem and have a ask around at the flying schools and ask them what they have to offer you!.. maybe start with a intro flight as well.
No there is not 40% female pilot in Qantas prob 5% if that.. but that does not mean you should not persue your dream... have fun and hop in!
