So on the weekend when Airservices connects Sydney radar class G frequency of 124.55 to retransmit on the Sydney approach/departure frequencies that's in conflict with the ICAO very sensible decision.
And our ATCs say nothing!
You have float planes yakking away at Brooklyn Bridge blocking out communication to a Qantas 380 on departure to LAX.
Only in Australia. It's amateurish. I wrote to CASA suggesting that the 120.8 Victor Lane frequency that I introduced after great resistance be extended to the Brooklyn Bridge area to reduce the chance of VFR self announce calls blocking ATC instructions on approach and departure frequencies. Got nowhere as they resist change.
