Scanorama,
There's heaps of foreign-born controllers in AsA, from all over the planet. Because you were born in Honkers - which from memory, isn't considered an English-speaking country - you will have to be checked against the ICAO standard. Curiously, this isn't done until after you've been selected! At the Academy, this is done by staff from RMIT. Trainees from English-speaking countries are assessed by specifically rated instructors.
