Umm - Ballina has a T-Vasis each end. Rwy 06 GNSS RNAV is about 5 degrees out of centreline alignment. Respectfully suggest if you cannot see the T-Vasis on manouevring the 5 degrees on long final you are not visual with the runway environment and should not be continuing the approach! Rwy 24 GNSS RNAV is exactly aligned and requires no manoevring, however.
For the "black holes" in smaller craft I was taught to examine the topos for obstructions and talk to locals first and fly at least 3 legs of circuit, for the turboprop/fan RPT I do agree that PAPI or TVASIS should be minimum.
Edited for spelling
