I'm booked in for ATC testing in Brisbane Oct 22.
I got a call the next day (23rd or so), but that may have been because I sent them an email asking to know results ASAP - I have some committments early November.
I thought the tests were pretty hard! Especially the recognition one (matching the random sequence of letters and numbers to the options provided).
I'm glad I found this thread, it has really helped in finding out more about the job and application process. Best of luck everyone!
