Protect people. Win work. Prove Safety.
ISO 45001 is the world's recognised occupational health & safety standard — and a mandatory ticket to federal tenders, construction prequalifications and Tier-1 supply chains across Australia. Fixed-fee certification, UKAS accredited, in as little as 12 weeks.
Occupational Health & Safety
Internationally recognised. Tender-ready.
What is ISO 45001?
ISO 45001:2018 is the world’s first international standard for Occupational Health & Safety Management Systems — built to stop workplace injuries before they happen and give Australian businesses a defensible, audit-ready WHS framework.
It’s the only OHS standard recognised globally, fully aligned with the Model WHS Act and Safe Work Australia codes — so you stay ahead of regulators, win bigger tenders, and build a safer business from the ground up.
One serious incident can cost more than certification ever will
Australian WHS penalties are among the highest in the world. Here’s what’s at stake — and what a certified OHSMS actually protects you from.
Reactive, exposed, and expensive
- Category 1 WHS breaches can attract fines exceeding $10M for corporations
- Industrial manslaughter laws now apply in most Australian states
- Rising workers’ comp premiums with every claim
- Locked out of tier-1 contracts and government tenders
- High staff turnover and reputational damage after incidents
Proactive, certified, and tender-ready
- Documented due diligence that stands up under regulator scrutiny
- Systematic hazard identification and risk control across sites
- Lower LTIFR and fewer claims — reducing insurance costs over time
- Pre-qualified for Avetta, Cm3, PQC and government supply panels
- Stronger safety culture that attracts and retains skilled workers
Why Australian businesses need ISO 45001
It’s no longer just good practice — ISO 45001 is becoming the baseline for winning work, managing risk, and proving due diligence under Australian WHS law.
Demonstrate WHS due diligence under the Model WHS Act
Officers and directors have a legal duty of care under Australian WHS law. A certified OHSMS provides the evidence trail regulators look for — and directors can rely on — when the worst happens.
Lower workers’ comp premiums
Fewer claims over time means measurable reductions with iCare, WorkCover VIC, and ReturnToWorkSA.
Win tier-1 tenders & prequalification
Sail through Avetta, Cm3 and PQC. Certified WHS is mandatory for major construction and mining work.
Cut lost-time injuries & downtime
Proactive hazard control means fewer incidents, lower LTIFR, and more productive days on the tools.
Attract and keep skilled workers
Safety culture is the #1 reason tradies stay. Certification proves yours is real — not just a sticker.

ISO 45001 questions, answered for Australian businesses
The real questions we get every week from Australian business owners, safety managers and directors.
How much does ISO 45001 certification cost in Australia?
Cost depends on your size, sites, and existing WHS maturity — but at IMSM, you get a fixed-fee quote upfront. No hourly billing, no scope creep, and no surprise invoices. Most small-to-mid Australian businesses complete certification for a lot less than the cost of a single serious WHS incident or Cat 1 breach.
How long does ISO 45001 certification take?
Typically 3 to 6 months depending on the size of your business and the state of your existing WHS documentation. Businesses with some systems already in place (e.g. SWMS, safety policies, incident registers) can often certify faster. Our assessors give you a realistic timeline on the discovery call.
Is ISO 45001 mandatory in Australia?
Not by law — but it’s becoming mandatory in practice. Most Tier-1 builders, government agencies, mining operators, and major head contractors now require ISO 45001 (or evidence of an equivalent OHSMS) before they’ll let you on site or award a contract. It’s also strong evidence of WHS due diligence under the Model WHS Act.
Will ISO 45001 reduce my workers’ compensation premiums?
Most businesses see lower premiums over time because certified OHSMS drives down claim frequency and severity. Insurers like iCare (NSW), WorkCover (VIC), ReturnToWorkSA and WorkSafe QLD factor your claims history and WHS systems into experience-rated premiums — so fewer injuries usually means real dollar savings within 12–24 months.
Does ISO 45001 cover psychosocial safety?
Yes — and this matters more than ever. Australian WHS regulators now treat psychosocial hazards (stress, bullying, fatigue, harassment) with the same seriousness as physical hazards. ISO 45001’s risk-based framework naturally extends to psychosocial risk, helping you meet the new Safe Work Australia codes on managing mental-health risks at work.
What’s the difference between ISO 45001 and AS/NZS 4801?
AS/NZS 4801 has been withdrawn. ISO 45001:2018 is now the current internationally recognised standard for Occupational Health & Safety Management Systems and is the standard Australian head contractors, regulators and insurers look for. If you’re still certified to 4801, now is the time to transition.
Can we integrate ISO 45001 with ISO 9001 and ISO 14001?
Absolutely. ISO 45001 shares the same Annex SL high-level structure as ISO 9001 and ISO 14001, so they integrate cleanly into a single management system. IMSM specialises in integrated implementations — saving you time, audit costs, and duplicated paperwork.
