The big big question is are you entitled to that magical first break.?
I think that EVERYBODY is entitled to that magical moment. Don't YOU???
some people get it handed to them early, some work for it and reap the rewards a little later.
Unfortunately
overhere, people are right, in that not too many twin jobs are going on the weekends. You might like to try some skydiving outfits.... some of them fly twins. I think down in Wollongong that a parachute mob there flies PA31's full of meatbombers.... and a place in Cessnock used to do that as well.
The other problem with ad-hoc charters is that sometimes they need you to be ready to go NOW!!!! ie living withing 20 mins of airport and be ready to be airborne in about 90 mins.
good luck though
