If you want to offer support to people aged under 18, you'll need a 'Working with Children Check' (called herein, WWCC). This is called a Blue Card in Queensland.
The system exists to help minimise risk of harm to children and young people.
Whether you require a WWCC depends on your 'usual' work.
"Usual" means your work is habitually or typically occurring.
The more checks and verifications you hold, the more 'trust' your profile shows.
