The Australian Government Building and Construction WHS Accreditation Scheme
The Australian Government Building and Construction WHS Accreditation Scheme was established under the Building and Construction Industry Improvement Act 2005 and is now administered under the Building and Construction Industry (Improving Productivity) Act 2016. The scheme requires that head contractors tendering for, or working on, federally-funded building and construction projects hold accreditation certifying that their WHS management system meets the Scheme Criteria published by the OFSC.
The financial thresholds that trigger accreditation are set by the Commonwealth and are periodically adjusted. The core threshold is that the Commonwealth funding contribution to the project must exceed $4 million including GST, provided the total project value exceeds $6 million. Certain specific categories of work — primarily large defence and infrastructure projects — have lower thresholds. If any of the triggers apply, the head contractor must be accredited at the time they enter into the head contract.
Accreditation is issued on a rolling basis and must be maintained through ongoing audits, corrective action, and renewal. The OFSC maintains a public register of accredited companies that is searchable via the OFSC website. Principal contractors working without accreditation on a scheme-applicable project are in breach of their contract with the Commonwealth and face contract termination, liquidated damages, and reputational consequences. The scheme is not a voluntary quality mark — it is a mandatory precondition for accessing Commonwealth construction funding.
For subcontractors, the scheme operates indirectly. Subcontractors do not need to hold OFSC accreditation themselves, but the accredited head contractor must demonstrate that their subcontractor management system meets the Scheme Criteria. In practice, this means subcontractors are contractually required to produce SWMS, WHS Management Plans, worker inductions, and incident reporting that aligns with the head contractor's accredited system. A subcontractor whose SWMS does not meet the head contractor's requirements will be refused site access.
What the OFSC Scheme Criteria Require for SWMS
The OFSC Scheme Criteria are the published set of WHS management system requirements that accredited companies must meet. The criteria cover leadership and commitment, risk management, SWMS and Job Safety Analysis, subcontractor management, incident investigation, training and competency, and continual improvement. SWMS are addressed specifically under the risk management and subcontractor management criteria.
The criteria require the head contractor to have a documented process for identifying high-risk construction work (HRCW), obtaining SWMS from the relevant subcontractor, reviewing the SWMS for adequacy before work commences, making the SWMS available to workers, monitoring compliance with the SWMS during the work, and reviewing the SWMS when conditions change or after incidents. Each of these steps must be auditable — that is, there must be documented evidence that the process was followed for each SWMS on the project.
The OFSC does not prescribe a particular SWMS template, but accredited head contractors overwhelmingly require their subcontractors to use a standardised format. The typical format includes a 5x5 risk matrix with pre-control and post-control ratings, explicit reference to the 18 HRCW categories in WHS Regulation 2025 Schedule 1, named responsibility columns showing who will implement each control, monitoring arrangements, review triggers, a consultation record, and a worker acknowledgement section. A SWMS that omits any of these elements will typically be rejected at the review stage and returned to the subcontractor for revision.
The criteria also require the head contractor to flow their requirements down to subcontractors through the contract, the WHS Management Plan, and site inductions. The OFSC audit process checks the contract terms, the WHS Management Plan content, the induction records, and the SWMS register as a coherent system. A gap in any of these documents can generate a non-conformance finding even if the individual SWMS documents are adequate.
How OFSC Audits Work in Practice
OFSC audits are conducted by OFSC Federal Safety Officers (FSOs), who may be OFSC staff or contracted auditors. Audits can be scheduled or unannounced, and typically involve a site visit combined with an examination of documentation at the head contractor's office. The FSO begins by reviewing the project's WHS Management Plan, then examines the SWMS register to see which subcontractors have submitted SWMS for which HRCW activities, then moves to sampling individual SWMS for adequacy against the Scheme Criteria.
On the site portion of the audit, the FSO observes actual work in progress and cross-references it against the current SWMS. If the SWMS specifies scaffolding with a double handrail and midrail, the FSO checks that the scaffolding on site matches the specification. If the SWMS specifies lock-out tag-out for energy isolation, the FSO checks that workers are carrying locks and tags. If the SWMS specifies a spotter for plant-pedestrian interaction, the FSO looks for the spotter. A gap between the document and the actual site is one of the most common sources of non-conformance findings.
The FSO then interviews workers on site. The Scheme Criteria and the WHS Act both require that workers be consulted in the preparation of SWMS and be made aware of the content. A worker who cannot describe the hazards or the controls for the work they are performing is evidence that consultation and induction were inadequate, regardless of what the paperwork says. This is why digital sign-on with auditable timestamps is increasingly expected — it demonstrates that induction occurred at a specific time before the worker commenced HRCW.
Audit findings are classified as minor non-conformance, major non-conformance, or critical non-conformance. Minor findings trigger corrective action requests that must be closed out within a specified timeframe. Major findings can result in conditional accreditation or suspension. Critical findings — typically involving imminent risk of serious injury or fatality — can result in immediate work stoppage and the issue of a notice to SafeWork NSW, WorkSafe Victoria, or whichever state regulator has jurisdiction over the site. Revocation of accreditation means the head contractor cannot continue work on any federally-funded project until the issues are resolved and accreditation is reinstated.
Subcontractor Obligations on an OFSC Project
Subcontractors working on an OFSC-accredited project receive their SWMS requirements through the head contractor's contract, WHS Management Plan, and site induction. The specific requirements vary by head contractor and by project, but several patterns recur across the industry. Subcontractors should expect all of the following as a minimum.
First, the head contractor will require a documented SWMS to be submitted before any HRCW commences on the site. The submission deadline is typically 48 to 72 hours before the planned start of work, to give the head contractor's WHS team time to review and return comments. Subcontractors who show up on day one with a SWMS drafted that morning will be told to stand down until the document is reviewed.
Second, the SWMS must use the head contractor's template or meet their minimum content requirements. Most accredited head contractors publish a SWMS template — often as a PDF form or an editable document — and require subcontractors to use it. Where the subcontractor uses their own template, the head contractor will map the content against their minimum requirements checklist. Any gap triggers a revision request.
Third, all workers must be signed on to the SWMS before commencing the relevant HRCW. Sign-on records must identify each worker by name, include the date and time of sign-on, and cross-reference the specific version of the SWMS that was acknowledged. Paper sign-on sheets with illegible signatures are the most common source of audit findings; digital sign-on via QR code or an inducted-worker database is increasingly the expected standard.
Fourth, amendments to the SWMS must be documented, re-acknowledged by workers, and reported to the head contractor within a defined timeframe. Silent amendments — where the subcontractor changes the document without telling anyone — defeat the entire SWMS system and are treated as a serious compliance failure. The change must flow through the review, acknowledgement, and register update process before work continues.
Fifth, the subcontractor must participate in the head contractor's incident reporting and investigation system. After any incident, near-miss, or dangerous occurrence related to HRCW, the SWMS must be reviewed and — if necessary — amended. The review must be documented and reported to the head contractor, who aggregates subcontractor incident data for the OFSC audit record.
OFSC vs Standard WHS Regulation Compliance
The OFSC Scheme Criteria impose requirements that exceed the bare minimum of WHS Regulation 2025. The regulation requires a SWMS to identify the work, specify hazards and risks, describe controls, and describe implementation, monitoring, and review (section 299). The OFSC criteria require all of this plus the evidentiary wrapping — documented processes, auditable sign-on, verifiable consultation, and a working register.
One practical difference is risk assessment format. WHS Regulation 2025 does not mandate a particular risk matrix or require both pre-control and post-control ratings. The OFSC does not prescribe a matrix either, but accredited head contractors almost universally require a 5x5 matrix with pre-control and post-control ratings because it provides the quantitative evidence of control effectiveness that auditors want to see. A subcontractor submitting a SWMS with only a narrative description of controls, and no quantified residual risk rating, will usually be asked to add the matrix.
Another difference is consultation. The WHS Act section 47 requires consultation with workers and HSRs in preparing the SWMS, but the regulation does not prescribe how the consultation must be documented. The OFSC criteria require documented evidence of consultation — typically a section in the SWMS listing the workers consulted, the dates of consultation, and any feedback that was incorporated into the document. A SWMS without a consultation record will be rejected as evidentially incomplete.
A third difference is responsibility assignment. The regulation requires the PCBU to ensure controls are implemented but does not require individual responsibility to be named in the SWMS. The OFSC criteria effectively require it, because without named responsibility the auditor cannot verify that a specific person is accountable for each control. The practical convention is to include a 'responsible person' column in the SWMS that names the supervisor, leading hand, or trade-specific role accountable for each control measure.
