Duncan from Blochaus is running the Black Range Bouldering meet again this year - check out the Facebook page for more info.
At this stage I'm just planning a day trip with a mate, leaving Canberra early and coming back when we have no skin left. Let me know if you want a lift. You'll just need chalk, shoes, snacks and water (no water on site).
If there's any interest, would definitely consider camping overnight and coming back the next day in the afternoon.
