• Urban-lining
  • Trick-lining
  • Slackline Yoga


Slacklining is the act of walking or balancing along a suspended length of flat webbing that is tensioned between two anchors.

Who Can Participate

  • Open to all
  • Some Activity Providers may have other restrictions e.g. age, experience or height restrictions.

Safety Rules

  • The minimum dress requirements are: T-shirt, and mid-thigh length shorts, sturdy lace-up jogger style shoes with good grip. Shirts must be tucked in. Long hair should be up and tuck-up in the helmet. Jewellery such as necklaces, bracelets, long earrings, rings and watches, must be removed.
  • All participants and Activity Leaders/Instructors must wear a helmet bearing the stamp of standards of Australia, when in the designated activity area.
  • In special circumstances, eg special needs members, it may be possible for individuals to participate in ropes activities in carefully controlled situations at the discretion of the Activity Leader/Instructor.
  • Participants are not allowed on the rope courses unsupervised.


  • Choose appropriate trees for slacklining; Always use tree protection. This protects the tree and your slackline.
  • Trees are the safest option and need to be a minimum of 30-35cm in diameter
  • Trees must be alive and healthy with a good root system.
  • Please avoid attaching your slackline to any ‘soft bark’ trees to avoid damage.
  • 5 to 10 metres long – tightened with a rachet,
  • Height of the slackline should be at the level of the smallest child’s thigh or lower.
  • Never attach your slackline to any government property or private company infrastructure (power poles, sign poles/posts etc), you may be liable for damages and you risk access for all slackliners.
  • Be aware of your environment at all times.
  • Never leave your line unattended…EVER.
  • Check your gear before you use it and regularly whilst you are using it. Sometimes ratchets unlock and shackle pins can work themselves loose.
  • Don’t rig your slackline across a path or place where people walk through regularly. Remember cyclists and pedestrians can easily miss a slackline.
  • Please use wind dampeners or high visibility tape on long lines to make your line clearly visible.
  • BACK UP YOUR GEAR! It’s as simple as tying parts (like a ratchet) to your anchor with the tail of your webbing or a sling.
  • This slackline is not intended for performing any jumps or dynamic tricks
  • Participants should not be allowed to use a slackline unless under constant adult supervision
  • Check your rig; ensure all attachments are secured/done-up before tensioning, monitor during tensioning and final check before walking – sometimes we miss things! Stay safe!
  • Consider rigging your rodeo-lines with a girth hitch to prevent slings slipping off of tree protection.
  • Do not tie any knots in your webbing or extend the length of your webbing by connecting other materials as this will
  • Respect authorities in all situations including police, council workers and parks/recreation officials. If they ask you to take down your line, first explain that you are causing no harm to the trees, if they persist then respect their decision. We need to keep a good reputation for slacklining in Australia.
  • Try to keep the equipment/bags of your community in one place to minimise impact and keep areas free of obstacles for other users of the area.
  • Please be conscious of the environment; leave no trace; take all rubbish with you.
  • Be careful in letting strangers try your lines as you could be liable for damages
