Prohibition Signs — Buyer's Guide (Red Circle + Slash)
Prohibition signs are AS 1319's 'MUST NOT' category — black pictogram on white background inside a red circle with a red diagonal slash across the pictogram. They prohibit specific actions: no smoking, no naked flames, no entry, no mobile phones, no photography.
Prohibition signs are commonly paired with warning signs to create a two-step message: 'DANGER — Flammable Liquids' (yellow triangle) + 'NO SMOKING' (red circle). This pattern appears at every fuel station, chemical store, and paint-spray booth in the country.

Smoke-free laws vary by state
Every Australian state and territory has its own smoke-free legislation specifying where 'no smoking' signs must be displayed and what wording they must carry. NSW requires specific text at outdoor dining, building entries and government buildings. VIC, QLD, SA, WA, TAS, NT and ACT each have slight variants. We stock state-specific templates.
