its some cliffs a mate found a few years back in an area north of Lithgow.
as far as we are aware there's been no ascents there apart from the few he has done, mainly due to the access. access was through some pretty full on 4x4 trails and permission off private land owners for access.
alot of potential, but your looking at atleast 6-8 hours to get access from Sydney so don't know who would bother ha.
the first time they went there was ground access which was horrible apparently but this time we had top access which was still a decent half hour swimming through healthy scrub bash then had to find a gully where our ropes could hit the ground.
