Description
The No Swimming pictogram — a red-ringed figure with a diagonal slash — signals prohibition across contaminated water, dangerous currents, non-potable reservoirs, treatment ponds, and stormwater detention basins. It meets AS 2416.1 and is recognised instantly by the public. Material choice depends on water type and exposure: marine aluminium withstands saltwater corrosion; polypropylene suits inland and enclosed water bodies. Available in four sizes from 225 × 300 mm (walkway markers) to 600 × 900 mm (perimeter fencing). Holes and lamination options are available for rapid installation and extended durability. Most local councils mandate No Swimming signs on detention basins as part of WSUD (Water Sensitive Urban Design) planning approval. Platinum Signs supplies trade contractors and councils Australia-wide with bulk discounts and next-day delivery to major cities.
Final sign type, wording, size, placement and material depend on the site risk, project specification and applicable jurisdiction. Confirm the requirement with the relevant WHS adviser or regulator.

Frequently asked
Which material is best for saltwater or coastal sites?
Marine-grade aluminium resists salt corrosion and is ideal for beaches, marinas, and estuarine water bodies. Polypropylene is adequate for inland freshwater only.
Do I need No Swimming signs on my detention basin?
Check your local council's WSUD approval conditions. Most councils require them on accessible perimeter fencing to meet water-safety compliance and duty-of-care obligations.
What size works best for a large perimeter fence?
Available sizes are 225 x 300mm (Small), 300 x 450mm (Medium), 450 x 600mm (Large), 600 x 900mm (Extra Large). Viewing-distance notes are a practical selection aid, not a substitute for checking the approach distance, lighting, mounting position, wording and site risk assessment.
Can you supply pre-drilled holes for fence mounting?
Yes. Four-corner pre-drilled holes are an optional extra with a base surcharge of $3.00 inc GST per sign for the listed configurations, before any applicable volume discount. Select the option to update the configured total before adding to cart.
Do you offer volume pricing for councils or contractors?
Yes. Trade accounts receive tiered discounts on orders of 10+ signs. Contact our sales team with your project scope for a formal quote.
