What safety and consent points apply when using Yulunga games?

The resource's disclaimer says:

• It is designed for people of all ages and assumes each participant is healthy and has no medical condition that would preclude participation.
• Nobody should take part if any medical, physical or other factor indicates the activity does not suit them.
• Where there are queries or concerns, the participant's consent, or their parent or legal guardian's consent if under 18, should be obtained before they take part.
• Adult supervision must be provided for all activities where participants are under 18.

Individual games add their own safety notes. For example, the boomerang entry says to keep your eyes on the boomerang, use another person as a watcher if possible, pick an appropriate large open area, set up safety regulation procedures, check wind direction and set aiming points, and agree where people sit when not throwing.
