Hey ADZ...
If you're keen to get involved in ATC then go for it
I'm not sure how strict access to control centres is over there but my best advice would be to contact them and see if you can get in there for a day or so, so you can watch and see what it's all about.
Some people see it all, go pale and we never see them again. On the otherhand, some people can barely contain their excitement and want to get in there straight away. Like I said though, contact your nearest centre and see if they can help you out. They'll also be able to tell you what to do from there...
Best of luck to you...
Keep us posted
Oh, and BTW, don't slack off too much, there are minimum requirements to get in...
