Australia’s hi-vis rules changed in mid-2024, bringing tighter colour and reflectivity limits, fresh guidance on trousers and new wording around risk assessments. If you buy, issue or wear high-visibility garments, the update affects you. This guide breaks down the latest AS 4602.1-2024 and AS/NZS 1906.4-2023 requirements in plain English, shows how they compare with overseas rules, and gives easy checks to keep your kit compliant.
Why compliance matters
- Legal duty of care – Under Work Health and Safety (WHS) laws, a PCBU must provide suitable PPE, including compliant hi-vis clothing. Penalties for proven neglect can reach six figures.
- Accident prevention – Visibility is a frontline control for struck-by hazards. Studies submitted to the 2024 standard review showed a 35 % fall in near-miss incidents on sites that switched to fully compliant garments (data referenced in Standards Australia briefing notes).
- Brand & contract risk – Major principals now write “AS 4602.1-2024 certified” into site specs; failure to comply can void tenders or insurance.
A brief history of hi-vis standards
| Year | Milestone |
| 1930s | Railway gangs hand-painted jackets to stand out on foggy tracks. |
| 1960s | Fluorescent dyes commercialised; first rail trials in the UK. |
| 1999 | Joint AU/NZ committee publishes AS/NZS 4602. |
| 2010–2011 | Major overhaul: AS/NZS 1906.4:2010 (materials) and AS/NZS 4602.1:2011 (design). |
| 2023 | AS/NZS 1906.4:2023 widens test methods; adds wet-weather class “W”. |
| 2024 | AS 4602.1-2024 released – clearer class rules, trousers now explicitly covered, new luminosity ranges. |
Understanding the two core Australian standards
AS/NZS 1906.4:2023 – materials
Defines how bright (fluorescent) or reflective a fabric, tape or panel must be after abrasion, washing and weathering.
- Class F – Fluorescent daytime colour
- Class R – Retro-reflective night tape
- Class RF – Both fluorescent & reflective
- Class NF / NF(W) – Non-fluorescent day materials, inc. cotton; “(W)” denotes wet-use approval.
AS 4602.1-2024 – garment design
Specifies how those materials are arranged on the body for high-risk applications – e.g. construction, traffic control, utilities. Key changes in the 2024 edition:
- Lower-body garments (trousers, overalls) now included in the scope.
- Tighter luminance factors for fluorescent yellow/green fabrics.
- Clearer tape placement diagrams for women’s fits.
Class comparison table – Day, Night & Day/Night
| Class | Light conditions | Mandatory materials | Typical garment |
| D | Natural daylight only | ≥ 0.4 m² Class F (fluoro) encircling torso | Two-tone polo with no tape |
| N | Night-time, lit by headlights | ≥ 0.2 m² background + 50 mm Class R tape (hoop / X / H) | Navy parka with silver tape |
| D/N | Day and night | Fluoro body plus 50 mm tape | Yellow drill shirt with biomotion tape |
Australia vs the world – quick snapshot
| Region | Main standard | Key difference |
| EU | EN ISO 20471 | Heavier focus on photometric performance; less on task context. |
| USA | ANSI/ISEA 107-2020 | Uses Type O/R/P, Class 1-3; permits smaller tape breaks. |
| Australia | AS 4602.1-2024 | Combines performance and application guidance; explicitly covers hot-weather natural fibres. |
Top FAQs
- What is the current Australian hi-vis standard?
AS 4602.1-2024 for garment design, paired with AS/NZS 1906.4-2023 for materials. - Do cotton shirts comply?
Yes, if the fabric meets Class NF luminance levels and the shirt fulfils Class D or D/N coverage rules. - How wide must the tape be?
50 mm (or two 25 mm rows) of certified Class R tape. - Are branded logos included in the colour area?
No, decoration cannot be counted towards the 0.4 m² fluoro requirement. - How long does reflective tape stay compliant?
Most tapes pass 30 domestic washes; check care label.
Care & replacement checklist
| Task | Frequency |
| Visual check for fading / torn tape | Monthly |
| Machine-wash ≤ 60 °C, mild detergent, no bleach | Every use |
| Line-dry in shade | After wash |
| Record garment issue & replacement date | On issue |
| Replace when colour drops below reference swatch or tape is cracked | As needed |

Conclusion
Hi-vis workwear isn’t just a bright shirt, it’s a regulated safety system. With the 2024 revisions now live, make sure every garment on site carries a clear Class D, N or D/N label, uses certified fabrics, and is replaced before wear and tear knocks it out of spec. Staying visible keeps your team, your contracts and your reputation safe.
