Burko,
You need to follow hanson road and take the turn off to the power station and follow this down the ramp to the roundabout. Turn left at the roundabout and then next right (very close to the roundabout) and follow this around to the outlet. A couple of picnic tables there and easy to walk the bank casting.
Bring some boots depending on tide you could be walking on grass or mud and rocks
Hope this helps
