If this is your first GAAR, or you are otherwise unaccustomed to the minutiae of Aviation Oz-style, please be aware that Australia invented it's own (technically superior) system of approach lights called a T-VASI which is still installed at some airfields. For those only used to PAPI and VASI lights, T-VASI can come as a shock, especially as the lights for a perfect T-VASI approach looks like a high PAPI-2 approach.
1) T-VASI only uses WHITE lights (no REDS).
2) If you see what looks like a capital T, with 2 lights in the crossbar, and 1/2/3 lights in the upright, you are SLIGHTLY LOW/LOW/VERY LOW.
3) If you only see 2 lights side-by-side you are on the glide slope
(unless they've installed PAPI-2).
4) If you see what looks like an upside-down capital T, with 2 lights in the crossbar, and 1/2/3 lights in the upright, you are SLIGHTLY HIGH/HIGH/VERY HIGH.
Unfortunately, I can't remember which airfields use which approach systems, but it probably wouldn't hurt to take a pre-flight looksee (unless, like me, you're English, and consider that such tactics would "spoil the fun").
