Macquarie Pass Canyon, or Macquarie Rivulet, is largely a scenic waterfall abseiling trip, though there are a couple of short slot-like sections.

I have not done this one before so I am looking for a co-leader, please reach out if you are keen. 

I'll limit the group size small - please let me know your canyoning experience/other relevant skills if I don't know you :) You must be able to abseil and swim and have prior canyoning experience. Final numbers depends on drivers and experience.

No pre-trip. People need to sort out the gears themselves. I'll be at the gear store on 11th to hire ropes if you also need to hire gears.
