Hiking and swimming down a slippery stream or river corridor while wearing wetsuits and other safety gear.  Constant movement, in a pristine environment.  Sometimes we climb down through sections of boulders and over and between fallen trees.  When we get to the waterfalls we use special canyoning harnesses and ropes to connect ourselves to safety lines so we can approach the edge safely.  At high waterfalls, or when it is shallow below we abseil or zipline.  If it is deep enough and suitable, we lie back and slide off the waterfall edge... if you like to free fall?  Then stand firm, take a breath and jump!


Canyoning tours, courses and river rescue training are adventure activities that contain a number of known and unknown hazards and risks, and that an unpredictable or uncontrollable natural event may occur that could possibly cause those on the activity serious harm or death. It is important that all participants undertake the activities willingly and understand there could be consequences should they ignore the directions of Big Rock Adventures Ltd guides and instructors or fail to disclose medical or physical conditions that may affect themselves or other participants. It is always OK to say “no” and we have a fun focused, “challenge by choice” philosophy.

Big Rock Adventures Ltd will take all reasonable and practicable steps to keep those involved in these activities safe, e.g., professional and qualified instructors as well as top-quality equipment while operating under an audited safety management system that carries the ‘AdventureMark’ brand.

Before joining any activities, Big Rock Adventures Ltd requires all participants to sign an acceptance of risk form as an acknowledgment they have read and understood what the known risks within the activities are, as well as a declaration that they are free of any impairment (drugs, medications, alcohol) and are physically fit and capable to join.  Big Rock Adventures Ltd is unable to guarantee participants safety and signing the risk acknowledgement and fitness declaration form does not waive our commercial obligations under the HSWA Adventure Activities Regulations 2017.


FITNESS - What is physically fit and capable for canyoning or river training?

Canyoning, river rescue and raft guide training require a reasonable level of physical fitness and agility.  You must inform us of medical conditions, pre-existing injuries, medical conditions and fears before the trip.  

  •  We wear wetsuits that are tight fitting and it's tiring to move in them.  If you can run up and down stairs without holding the handrail, no problem.  If you are not fit, this could cause you to fatigue faster than usual.  

  • People with heart and respiratory conditions should consider that the tight fitting wetsuits and cold water may restrict your ability to breath comfortably and this could stress a medical condition.

  • Jumping and walking in the canyon environment requires some agility.  If you can jump from the ground up stairs without holding the handrail, no problem.  If you can't jump, we may not let you do the jumps and set up an alternative means for you, like an abseil or zipline instead.


As a commercial operator we are required to take every practicable step to make our workplace as safe as possible for ourselves, our guests and the wider community.
