Moree is NOT a black hole approach from either end. I've been into there at night on hundreds of flights in varying Wx conditions.
Agree with Aimpoint in this instance. There are many worse airports for night approaches.
HMAS Grafton springs to mind as a typical "black hole approach", but it had a VASI last time I was there. Now has a PAPI. Plus it had 90m spacing on the edge lights which gave conflicting illusions with the VASI, too.
