Straight ahead eh!

I have been amused by the road markings on this roundabout for some time now. It is near Nelson Bay....according to the road markings as you approach (from bottom of picture) you can turn left or go straight ahead from the left lane, turn right or go straight ahead from the right lane....the thing is, ... straight ahead puts you into the trees!, as in reality, you can only go left or right ....gotta laugh!
note: there is a similar marking on the inside lane approaching from the right of the picture.
