Flightwatch Southern working various flights. this is my first time logging this. previously i have logged Flightwatch NW Australia on 6541 around the same time. the 6565 frequency was hard to copy at times due to it also being an HFDL frequency.
as a rule if i can hear VMC or VIM on 6507 i check these Flightwatch frequencies:
6541 Flightwatch Northwest
6565 Flightwatch Southern
6610 Flightwatch Northeast
Unlike MWARA HF frequencies which typically are used for international flights often over ocean, Flightwatch frequencies i believe are used for internal domestic Australian flights.
