If you want indoor then just go to either The Rockface or The Hangout and ask. They both have intro courses. I did the course at The Hangout. It was 1 night a week for 8 weeks.
Adventure Out also does the Intro to Rock Climbing Course which is conducted at Churchman’s Brook just outside of Armadale. But it’s not much good if you don’t have the gear (or don’t intend on buying it anytime soon) to be able to rig your own setups outdoors.
