For those waiting to hear about their conversion courses. You'll just have to be patient. It took me 8 months between application to commencement of training for an experienced ATC position. You'll be offered a salary table which isn't the same as in the collective agreement. Less than 6 years experience expect field trainee rate while in Melbourne college, level 1 in field training, and between 2 and 4 once rated. Less than 10 years expect levels 1, 3, and 5.
Depending on your training needs analysis the RADAR tower course (SY BN ML etc) is about 9 weeks long. About 3 weeks of theory (SAR, IFER, etc), about 5 weeks of simulator training, and 1 week of MET. In Sydney you normally start your OJT on SMC west ADC east and delivery. BN now start trainees on ADC as SMC has become much more complex recently.
By the way don't assume this is set in stone, it's only based on experience.
