No entry signs control access to restricted areas and communicate clearly to workers, visitors, and the public that entry is not permitted. Whether you are securing a hazardous area, protecting plant and equipment, or managing visitor flow through your site, the right no entry signage is a fundamental part of your access management and WHS compliance framework.
Industro supplies no entry signs to workplaces across Australia — from small businesses securing a plant room to mining operations managing access across large sites. Our range covers the most common no entry and restricted access scenarios.
No entry sign types
- No entry — general exclusion for unauthorised persons
- Authorised personnel only
- Restricted access — specific area or role-based restrictions
- Keep out — hazard-based exclusion
- No unauthorised entry with contact details
- Danger — no entry signs combining hazard and access messages
Access control and WHS obligations
WHS regulations require that areas containing hazards inaccessible to unauthorised persons are secured and signed appropriately. For high-risk areas, a no entry sign alone may not be sufficient — physical barriers combined with clearly displayed access restriction signage is the required standard.
Correctly placed no entry signs also protect your business in the event of an unauthorised access incident by demonstrating that reasonable steps were taken to prevent entry.
Why buy from Industro
Our no entry signs are available in a range of sizes, from small door and panel signs to large format signs for site entrances and outdoor installations. Materials include self-adhesive vinyl, rigid polypropylene, and aluminium for permanent outdoor use. Stock signs ship same day from our Australian warehouse.
What size no entry sign do I need?
Sign size depends on the viewing distance required. For a doorway or panel, a 225 x 300mm sign is typically sufficient. For outdoor site access points visible from a vehicle, 450 x 600mm or larger is recommended. AS/NZS 1319 provides guidance on minimum sign size for given viewing distances.

Yes. We produce custom access restriction signs with specific instructions, contact details, or site branding. Contact us with your requirements for a quote.
