Jumpu, I think you are totally missing the point. The problem is not overseas students its the training the get in Australia that is at fault. .
There are a number of Universities in this town that teach English to overseas students for a whole year before they can attend University and at least two of them do a totally rotten, expensive and corrupt job of it, passing students and giving them certificates when they have an absolutely abysmal command of the language.
I've seen three badly damaged Cessna's all with the same "nosewheel" problem and on more than one occasion watched the most unbelievable antics, including one guy who saved tyre tread by floating almost the entire length of 35R!
Thats one of the reasons I'm for mandatory calls as opposed to "recommended' calls. I'm concerned that after the 25th, some of these kids are going to go out on navex's and not utter a peep along the way because they don't have to and because its easier that way.
