At SYD it can be much more limiting than even your "bog standard" Cat 1 RVR minima of 550m, FWIW during the Southern hemisphere Winter season the BA 15 is one of the flights allowed and scheduled to land before the end of the night curfew. That means "it is a requirement"
to use 34L.....and from memory the RVR requirement for a CAT1 to 34L is something like 1.5
km (no approach lights)....
