So when are you going to jump into a VH-registered aircraft and tootle around without a clearance in an active Romeo, 13nms on the seaward side of the territorial sea baseline?
Ultimately, that's the only way to test your theory.
I keep telling you: Although Australia cannot regulate foreign aircraft in international airspace, Australia can regulate Australian aircraft anywhere in the universe, and that includes more than 12nms on the seaward side of the territorial sea baseline. But I could be wrong...
