Buckshot I love it. If you are taxiing at an unmarked aerodrome near a frequency boundary ( like Wilpena) you give the taxiing calls on both ATC area frequencies .
No, you use a bit of common sense, and call on the one applicable to the direction you're going. That's where any conflict will most likely be coming from.
How long did it take you to find a suitable unmarked strip near a boundary, to support this fatuous argument?
Like nothing else in the world!
Maybe we've accepted here that see-and-avoid is not the perfect solution, and that a timely radio call adds to the general awareness.
Maybe it's because we're not Americans, who need to impart their entire life story over the radio, so we are capable of keeping it brief.
Maybe we're aware that a VFR aircraft will hurt just as much as an IFR if you hit it.
Really good info for high flying jets. They must think we are mad!
No, they (we) don't.
