As a matter of interest what monitoring/capability does ATC have on adjacent frequencies.
A couple of years ago I had a VCA between Toowoomba and Caloundra when I got on the up escalator. As control was limited to wings level and airspeed in the middle of the green; I wasn't going to try and change frequencies on a microair or read VTC/ERSA. Called on the Caloundra freq which covers several fields requesting someone relay to BNE the situation and that I would descend when able (not that I was that keen, updraughts like that probably mean similar downdraughts nearby).
No reply and never heard anything else about it.
