A couple of other spots or bouldering up that way!
Hazelbrook - Queens Rd, drive down it till it turns to Dirt and you go under the power lines. Very shortly (100m) after this is a pullout and track on the L. Stop here. To the L (W) is a large slab or rock (lookout). Bouldering is below here. A small area but there are some good problems and good rock spread amongst the sandy sections.
Mt York - walk down the trail to the R side (N) of the car park loop where the green shed is. Walk down this past the abseil site and into the little valley. There are some nice boulders and walls in this sheltered little area and hillside that Garth and I used boulder on in winter when the wind was blowing in 2000. Was there last week and its still good.
