If you like steep stuff, I would much recommend to check out Blue Bell in Sydney South. Have a look to the guide on The Australian Climbing Association website (Blue Bell online guide). There are 17 routes graded from 18 (5c+) to 26 (7b+) , with an average of grade 21 (6b+). Basically the wall is about 15m high and 10 degrees steep. The routes are well secured with lots of bolts. With Laurent we onsighted one 21 (6b+), three 23 (7a) and redpointed one 25 (7b). We had such a great time on this wall.
