Just a thought but I wonder if the Sydney training area West of ysbk should be given its own ctaf? I think pilots would benefit from hearing an entry broadcast and perhaps intentions of manouvres when approaching or transitioning that area. The airspace can be quite crowded there some days especially sunny Saturday mornings. Plus it’s good radio operator training experience for the students.
I know we have Syd radar 124.55 and I’ve heard broadcasts for a/c performing stall training on that freq, but I wonder if a dedicated freq that all t/a traffic monitor would be more effective?
