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

The trip limit is 4-5 - 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 ideally have prior canyoning experience. Final numbers depends on drivers and experience.

No pre-trip. Unfortunately gear store is closed but let me know if you require gear.
