ISO 45001 certification in Australia: JASANZ accreditation, contractor prequalification and multi-jurisdiction safety duties

Why Australian organisations pursue ISO 45001

In Australia the request for ISO 45001 usually arrives with a contract. Head contractors vetting subcontractors before they set foot on site, resources and energy companies approving service providers, facilities and labour-hire clients running supplier reviews, and public buyers scoring tenders all want proof that safety is managed as a system rather than left to a single safety officer. A certificate from an accredited body answers them.

Public procurement already treats accredited certification as an entry condition in places. The NSW Government's quality management guidelines for construction, for instance, call for independently certified quality systems from a body registered with JAS-ANZ. That rule concerns quality rather than safety, and safety expectations differ from one agency, scheme and contract to the next, so read every tender and prequalification form for exactly what it asks.

Australian arms of international groups face a second pressure: the parent wants every country on one safety system and one set of indicators. See the ISO 45001 benefits guide.

The local landscape: JASANZ, Global ACI and certificate checks

The Australian Government describes JASANZ as the bi-national body providing independent accreditation of conformity assessment bodies across more than a hundred sector schemes. JASANZ itself states plainly that it does not certify management systems; it accredits the organisations that do.

For your project that separates two checks. First, which certification body will audit your workplaces? Second, is that body accredited by JASANZ for OH&S management systems, with a scope that fits your activities? Accreditation is granted scheme by scheme, and a body accredited only for quality management cannot issue an accredited ISO 45001 certificate. Request the body's accreditation schedule and match it against the directory; the guide to choosing a certification body sets out what else a sound quote should state.

Since 1 January 2026 international recognition of accreditation has run through Global ACI, which took over the roles of the IAF and ILAC. Because JASANZ was not visible on the Global ACI recognised list at our last check, anyone relying on the certificate outside Australia should check both sites first.

Clients checking your status will search the JASANZ Register of certified organisations for your name, the sites and activities covered and the issuing body. The certificate verification guide walks through each step.

Local practice that changes the project

A legal register for every jurisdiction

Safety duties in Australia come from legislation that applies jurisdiction by jurisdiction, with a regulator enforcing it in each, and the detail differs across borders. ISO 45001 requires you to identify the legal requirements that apply to your hazards, evaluate compliance and act on gaps. A company with a Sydney head office and crews in two other states needs a register that shows which rules apply where, and who evaluated them last. The legal register guide explains the method.

Contractors, labour hire and shared sites

Much Australian work happens on sites controlled by someone else, alongside labour-hire workers and subcontractors. Your scope must say who falls under your control, how duties are shared with the principal contractor or host client, and how inductions, permits and consultation reach people who are not your employees. The certification body sets audit time from effective headcount including contractors, so count them accurately. See the contractor management guide.

Remote, fly-in and project-based work

Mining, energy and infrastructure work often runs on rosters at remote or temporary sites. Plan Stage 2 for a period when representative high-risk work is active on a site the auditor can reach, and allow for travel and site access rules in the audit plan.
