That is spot on C17.
When I was as Flight Screening last year, they were very clear that the RAAF were only really after fast jet pilots. They have also implemented a 'Gate' for RAAF members after BFTS. This is a check point meaning that just because you pass BFTS, it doesn't mean you automatically progress to 2FTS. If you pass, but are not in the top candidates, you will not make it through the gate and might possibly be streamed to ACO, or something else in the RAAF.
Right about Army, and Navy only has about 3 spots per NEOC intake.
