Nvfr? No such thing.
Unless you are flying around a major city of several million people with its associated illumination there's NO such bloody thing as NVFR. Especially if you are anywhere near the GAFA which is blacker than the inside of cow.
It's quite simple, night, outside of the immediate confines of a very large metro area is IMC and any legends who think they know better are just kidding themselves and are endangering themselves and their unsuspecting pax.
If you go out at night you need an IFR equipped aircraft and an instrument rating that is well used.
Just how many night time crashes and deaths are required for CASA to stop this nvfr bulldust?
