ISO internal audits provide senior leaders with independent insight into how management systems perform against recognised best-practice standards, and whether those systems operate as intended in practice.
ISO standards, including ISO 45001, are not legal requirements. They are voluntary frameworks that organisations may adopt to structure, monitor, and improve management system performance. An ISO internal audit provides objective assurance by testing documented ISO requirements and how those requirements are applied in practice.
For broader assurance over legal alignment, system ownership, and leadership accountability, a WHS Systems Governance Review provides the appropriate starting point. That review can incorporate consideration of ISO alignment where relevant, while examining governance design, legal requirements, and system effectiveness as a whole.
ISO internal auditing may then be used as a targeted assurance activity to test conformance with specific ISO requirements where independent, standard-based assurance is required.

We primarily conduct ISO internal audits against ISO 45001 Occupational Health and Safety Management Systems, with ISO 9001 Quality Management System audits undertaken where required to support integrated management systems or client obligations. Audits are conducted independently by our qualified and experienced ISO 45001 and ISO 9001 internal auditor.
ISO 45001 internal auditing provides structured, independent testing of how work health and safety risks are managed within the standard's framework. This includes examining whether risk identification, control measures, monitoring, and review processes are implemented as described and operating consistently across the organisation.
For senior leaders, ISO internal auditing provides:
This assurance supports informed decision-making, while remaining appropriately bounded to the scope of the ISO standard.
ISO internal audits are scoped to reflect the organisation’s operating context, risk profile, and assurance needs. This approach applies to both ISO 45001 and ISO 9001 internal audits.
Audit scope may include review of:
Audits are conducted independently and with professional judgement, with a focus on system performance against ISO requirements. Findings are documented clearly, with prioritised observations and practical recommendations aligned to risk significance and leadership oversight needs.
ISO 9001 internal audits are available where quality management systems form part of an integrated management system or are required to support contractual or client assurance expectations.
While ISO 9001 auditing is not the primary focus of this service, it may be undertaken where quality and WHS systems intersect, and independent assurance against both standards is required.
WHS Systems Governance Review - “Andrea recently conducted a comprehensive review of our operations, and her expertise was evident from the outset. She approached the project with a high level of professionalism, ensuring that every aspect of the review was thorough and detailed. Andrea not only identified areas of improvement but also provided clear, practical recommendations that have added real value to our business. Her ability to balance technical knowledge with clear communication made the process both efficient and constructive. I would confidently recommend Andrea to any organisation looking for a trusted and highly capable safety consultant.” — Terry Wode, Chief Operating Officer, Moco Food Services

If your organisation relies on ISO-aligned systems as part of its governance and assurance framework, ISO internal auditing provides independent confirmation of how those systems operate in practice.
Where assurance is required over legal alignment, governance design, and leadership accountability, a WHS Systems Governance Review should be considered first, with ISO internal auditing used to support targeted, standard-based assurance.
