I was going past Limberlost unloading area yesterday and stoped to have a quick look.
It still looks good, the area and toilet it was clean apart from the one drink can that I picked up.
There has been no more information posted there by the DSC but I did see a sign that showed a motorcycle an arrow and a route number next to it, maybe they have sign posted a few routes from there.   
Hard to say how much use it's getting but you can see that it's being used for doing donuts by people in cars.
