In reply to HenryC: Hi Theeni, I used to live in Sydney and was active with the SRC, as business secretary for 2 yrs.
The reason the Three Sisters formation was closed was twofold, the first and major concern to the NPWS was the erosion on the West Wall route (it was the trade route and was being used by all and sundry etc). The erosion scar was clearly visible from the main tourist lookouts at Echo Point and in consultation with the local climbers and clubs it was agreed to ban climbing there. Secondary was the danger of rocks being dislodged onto the tourist path below some of the routes, but these routes were scarcely climbed anyway. However the traverse off the West Wall route does pass above a path and has a bit of loose rock around.
I was there 2 yrs ago and the ban is still in place.
I can vouch for the route Sweet Dreams, much better than West Wall, with a choice of finish at Grade 17. Re double or single rope,double ropes will be better for most of the trad stuff in the Bluies (good sport climbing at Nowra), unless you are only going to do sport climbing along with a std rack will be very helpful, if not essential on some of the longer trad climbs.
There are other easy climbs around the area, Mount Boyce, Zig Zag, Piddington and excellent single pitch sport at Shipley Upper.
If you can find other climbers a trip to The Wolgan Valley will give you a true taste of more remote BM climbing, on the far side of the mountains where they discovered the Wollomi Pine dinosaur tree several years ago.
Public transport from Sydney ie train or coach will get you close to some of the climbing, but be prepared for 30 to 60 minutes (or more) of walking to most areas. Easiest access I can think of is Blackheath township where it is possible to walk from station to Shipley Upper and Mount Boyce.
Go to Leura if you want to do Sweet Dreams, other easy but "adventurous" climbs here also. For Zig Zag and Piddington go to Mount Victoria.
Mount York has tons of climbs, but is a long walk from Mount Vic and would be best to get a taxi or jag a lift.
The SRC, are often contacted by overseas climbers looking for partners or just others to show them around and you could always try giving them an email or dropping in on one of their meets, they used to meet once a month at Petersham Returned Services League Club, check this may of changed
I have plenty of bolt bkts if you need to borrow them (where are you located?), slipping a wire over the bolt head is a risky last resort.
