In Queensland (and all Australian states/territories), the minimum legal age to serve alcohol is 18. This applies to any licensed venue: bars, pubs, clubs, restaurants, bottle shops, casinos, and events.
Before starting work, you must complete a Responsible Service of Alcohol (RSA) course from a Registered Training Organisation (RTO). The nationally accredited unit is SITHFAB021 – Provide responsible service of alcohol.
You cannot serve, supply, or sell alcohol in any capacity—even with supervision. You can work in a venue in non-alcohol roles (kitchen, cleaning, hosting) if the license permits minors on premises.
Office of Liquor and Gaming Regulation (OLGR) conducts covert audits. Fines: up to AUD $10,000+ for venues; AUD $3,000+ for individual staff. License suspension/revocation possible.
Bottom line: Turn 18 → do RSA → serve legally. No shortcuts.
