Lead balloon. Yes the multicom, 126.7
Buzz. You have not found it a problem because in some areas you are on a completely different frequency at flight levels and more importantly the CASA requirement is rejected by the vast majority of pilots .
In the US the only requirement for VFR radio equipped aircraft when flying en route is to monitor 121.5. This is primarily for interception reasons after Sept 11 - but it's great if you have an emergency like an engine failure because a call on this frequency will be monitored by high flying aircraft even if you are at 500' in a valley.
They clearly don't have VFR aircraft flying en route involved in mid airs with aircraft in the circuit area of CTAFs so there is no known safety problem to be addressed . And they have about 30 times the number of aircraft in approximately the same land area.
I suppose commonsense says a pilot doesn't fly through a circuit area of a marked strip. If the strip is not marked it must happen from time to time but has obviously not resulted in a mid air that would get the FAA looking at changing the system.
It's all about perceived risk compared to actual risk. We work on perceived risk.
