Hi Dan,
a good place to meet climbers is at CAWA events. We have regular ‘gym crashes’ at one of the climbing gyms, and also trips away. The last trip was to Albany for a week, just after Christmas. The next trip will be over the Australia Day long weekend.
A bunch of us also regularly go to one of the local crags on Sunday afternoon, and you are welcome to come along. I’ll put your email address on my list if you like.
