Morning.
Yes ADI only and there was pretty much a job waiting for me when I finished, as the colleges tend to hear what vacancies are going where before they are published (despite what people may tell you, there are some airfields who don't just use student CVs to fashion big swords out of and duel).
If you're going to do ADI AND APS you're looking at the best part of 28k, whereas ADI is about 13 now.
It's up to you though I guess. You can chance it and apply to a unit and hope to get signed up and guaranteed a radar course, or you can apply to tower only units, or get a radar licence and hope to get a tower course. There's heaps of options really but it will require quite a bit of money and a lot of work, but it seems you have the motivation.
As a side note I have a mate who validated at a big unit in t'north and he said that that the most intense, hard and baffling course throughout the whole of training was the Basic course at college as there's so much new information coming at you and it's stuff you've never really experienced before.
Once you're in it's a great job, I suppose just getting there is the hard part. Some may disagree but that's my experience anyway. Hope it helps in some way. All the best.
