Even if you find Fiegs overhang which is 70m north of the main cave on the east side of the ridge you probably wont locate those routes which are 2 tiers above. Currently they have had 1 ascent and rap anchors arent installed so we downclimb a grade 10 chimney to get off . Unless you like a bit of dirt and vegetation in your cracks and dont mind a little loose rock you may not enjoy Bulahdelah trad climbing. Belly button, and the Cleavage on the second (Bellybutton) pinnacle are probably the most acessible trad routes up there, via the mountain car park (which it is best to walk to after crossing the bridge over the new bypass, rather than drive up the hill). There are also 3 decent trad routes on Perfect Wall and a couple of OK trad routes on the Green Wall.
You can email me if you want further info.
