When I got my Radio Operators License (or was it the PPL? .. can't remember ... too long ago) in 1988, CASA (or known as the CAA back then) required me to sit an English proficiency test because I was born outside of Australia, despite the fact that I had done all my schooling in Australia, completed HSC English, have a Bachelor of Science degree as well as a Diploma in Education, and was working as a Secondary School Science teacher at the time! LOL! Go figure!
