NFR,
Sorry, I take your point. I was using ATC where I should have said AirServices Australia. I appreciate it's not the person on the radio. Nor is it my choice to visit these scenes, I just drive the taxi as safely as I can. We do check when in doubt, but have no reason to think there would be a TRA in this case.
I know that we must work within this system and all pilots do their best to monitor the area frequencies. However it is often the case, even with two radios, when you have to be off it. That area frequency is also often in competition with more urgent comms needs e.g. for the media choppers, the need to separate each other at a scene.
In the past we have provided aircraft and personal phone numbers to both ASA and the Police. The Police also know the media outlet phone numbers and have PA type systems in the NewsRooms over which they make relevant announcements. These are far more effective and efficient ways to contact us, if necessary.
