The RWY 19 ILS at BNE (via Leaky-Boats-Sinkk) is now given to both airlines. There is no restriction on DJ operations. I believe it was the QF 767's that were not permitted (company restrictions) to do the visual arrival by night or day but a QF driver might be able to shed some light on that.
I have heard that the current restrictions on the 19 viz approach at night are due to night time viz approach requirements leaving you high.
ATC seem to be quite happy to offer you a visual approach once on a rough downwind if available anyway but will not issue the 'Visual' STAR.
