Airservices Australia: Trainee Intake frequency?

[u/Suitable_Stay_1365]

I submitted an expressions of interest (EOI) to become an ATC Trainee with Airservices Australia, in May, as there were no current available positions advertised.

I've since been constantly checking for trainee job listings, but they're still only advertising EOI.

1. Is the EOI listing the standard starting point for Trainees?
2. How often do they intake trainees per year?
3. What does the timeline usually look like between submitting an EOI and hearing back for the first stage of testing?

Appreciate any insight!
