Stikman,
Couple of things :- What is your 1300TT made up of..? If its all SE piston then that won't help much (although its better than someone with the bare 200TT). Also, without wanting to pry about your personal circumstances, unless you're financially secure or you have a partner earning a good wage, trying to live on a GR3 instructors wage in Melbourne is pretty much impossible (especially if you have financial commitments such as kids, mortgage etc). Its a common dilemma. You'd need an instrument rating to get a charter job, but they'd also be looking for decent multi time as already stated. If you really are tied to Melbourne then I'd say the instructor rating would be your best bet. If you're lucky enough to get a job with a good school that offers progression through the ranks, then you will get the opportunity to work your way into multi and IFR stuff soon enough. Just be sure that instructing is really what you want to do. Its not for everyone. Can get a bit tedious after a while, and there's nothing worse than the booking sheet getting totally wiped out for the day due weather! Still, if you can cope with the (especially early on) low pay and you have a passion for instructing then go for it. I wish you well whatever you decide.
