if i was you, choose the country u want work/live in, then go there, do a full time CPL , and then work in that country afterwards. The sort of flying you want to do, you will need to spend time in that country/hanging out, getting to know the bush operators.I would stick in one country, as changing countrys mean more licences/flight tests etc etc. You can get job cattle mustering in oz, with less than 500 hours TT, its all about luck landing the first job.I got bush job in oz with about 450 TT, right place, right time, the key to bush flying is networking, getting to know people,prove to them you can do the job, and cope with all the aspects of bush flying, as basically you are on your own, and any problems you need to deal with them.Good luck, its the best flying you will ever do, i did for 2.5 years, lived in a remote area , and looking at my logbook did about 2700 landings in 2.5 years!Chase your dream!
