Well said Matt. Another soldier that won't give up - good for you.
Pilots are now considerd for immigration to Oz for what I could (briefley) make of the rules. Also I have seen that their tower signal test is only done at 300 and 500 metres (I will stand to be corrected of course) which would allow you to go to ATP and no weight restiction and international flying. The FAA tower signal test which I did and passed was done at 1000 and 1500 yards, so the Australian one "should" be easier. Australia is a fantastic place but my family etc are in the UK. It is about time the Uk (and Europe) got off their high horses, saw sense and followed the Australian example. Lets face it the medical is only the first step to CPL/ATP you will be assesed many times through training and again after, so if you can "cut the ice" you should be allowed to fly.
Good luck with your PPL mate and keep flying.
