sectored light, can be easily surveyed from the harbour bridge cycleway. 

1. Red if you're too far to port (cbd side)
2. White along the range line
3. Green if you're too far to stbd (milsons Point side)

There is some lens flare at the sector boundaries, so it's unclear if there are meant to be 3 sectors (RWG) or 5 sectors (RWRWG)

Exact bearings are also unclear, presumably the range line is parallel to the leading line formed by the 2 other beacons on this island. 

The characteristic appears to be Oc, with a period of circa 2 seconds ?
