Club Respect has developed B.A.S.I.C, a process guide for you to follow to support a person in the club who approaches you to discuss a health and well-being issue.
There is one vital aspect that must be considered here however. If the person is a child and you believe they are in danger then you must let them know that you have to report. Each State and Territory has its own Child Safety Laws. Go to Play by the Rules for further information.
