There are four primary levels of regulations and guidelines across Australia and New Zealand:
Level 1: WHS Legislation
The strongest of these is the first level, which is enforceable by law and comprises the WHS Act and WHS Regulations in Australia, and the Health and Safety at Work Act 2015 in New Zealand. The Australian rules came as a result of a 2009 National Review into Model Occupational Health and Safety Laws, which led the Commonwealth, Territories and States (except for Victoria) to adopt the Model Work Health and Safety Act (WHS Act) and the Model Work Health and Safety Regulations (WHS Regulations). The WHS Laws in each jurisdiction are therefore broadly the same (subject to minor variations). New Zealand’s Health and Safety at Work Act 2015 was based in part on Australia’s Model WHS Act (subject to some variations).
Level 2: Mandatory national standards
In a limited number of circumstances, WHS regulations mandate compliance with particular national standards or at least parts of them. This means that failure to comply with that standard can amount to a breach of the applicable WHS law.
Level 3: Codes of practice
The WHS Act authorises the Ministers in each jurisdiction to approve a code of practice. Codes of practice should be followed and can be used by safety regulators in a prosecution as evidence of steps that could or should have been taken to comply with the law.
Level 4: International standards
International standards such as ISO 45003 – set by the International Organization for Standardization (ISO) – provide guidance for how to comply with duties under WHS laws, but they are not enforceable unless compliance is specifically mandated in WHS regulations. However, regulators looking for evidence of compliance with legislation may reflect on the observance of recommendations in guidance documents, and organisations may choose to mandate compliance as part of a contractual requirement.
