GG, I'm talking from my personal experience. I was up here during what people told me was the peak time, a few months before the start of the dry season after completing my cpl a few years ago and missed everything. I took the attitude that there is no set time to be anywhere, but that the soon you can get you name out the better. If it meant hanging around somewhere pouring beers, stacking shelves or working in the servo to earn some coin while looking for a flying gig then so be it. I actually think it was you who told me on here once you won't get your first job sitting on the other side of the country, some of the better advise I've gotten from pprune.
Touch and go, then north is pretty expensive to live in, so either be prepared to find some casual work quickly, or have alot of savings when you finally decide to head up here.
