If you go out to Hawkebury Lookout and follow the fire road along fromYellowmundee Park at the bottom you'll get to some areas that have potential. I found one spot that would yield probably about 30 40 problems of various styles about 30-40mins walk along the trail......
other than that there is a ridiculous amount of rock in that region. I reckon if you went out to the Sackville Punt and got a tinnie and went up and down the river you'd find some DWS. Good hunting.
