Western Australia's new Work Health Safety Laws

Updated: Nov 2

Western Australia's Work Health and Safety Act 2020 (‘WHS Act’) replaces the Occupational Safety and Health laws in the State.


Work health safety laws are federal, in that, they apply in each State, but they are a little different in each jurisdiction.

A National Scheme

Safe Work Australia is a national policy body responsible for the development and evaluation of the model WHS laws (the model laws), which are comprised of:

  • model WHS Act

  • model WHS Regulations

  • model Codes of Practice

The model laws have been developed for implementation by all jurisdictions (that is the Commonwealth, states and territories), however they do not apply in a jurisdiction unless the jurisdiction has separately taken action to implement the laws as their own WHS laws.

The model laws have been implemented in all jurisdictions except Victoria.

Each jurisdiction has a WHS regulator that:

  • enforces WHS laws

  • inspects workplaces

  • gives advice.

The Commonwealth, states and territories are responsible for making their own work health and safety (WHS) laws.

Each jurisdiction has a regulator who monitors and enforces compliance with WHS laws. They also:

  • give advice and information on WHS duties

  • collect, analyse and publish statistics

  • promote and support education and training

  • help duty holders, workers and representatives consult and coordinate on WHS matters

  • promote and share information, tools and initiatives, including with other regulators.

Regulators work collaboratively to set strategic priorities at both a national and local level. Regulators work together to implement national campaigns and ensure a consistent approach to compliance and enforcement across Australia. They also share information, tools, and initiatives. All jurisdictions, except Victoria, agreed to a national approach to comply with WHS laws during COVID-19.

A Person Conducting a Business or Undertaking holds Liability

The new Work Health Safety Act introduces the definition of the ‘person conducting a business or undertaking’ - or PCBU. A PCBU can be:

  • a sole trader (for example, a self-employed person)

  • each partner within a partnership

  • a company

  • an unincorporated association

  • a government department of public authority (including a municipal council)

Employees now called workers, and workplaces are listed to included: labour hire; volunteer associations; supporting associations; school canteens.


An officer, or Director of a Company or Partner in a Partnership are defined as those involved in making decisions affecting the business.


If you are a business owner, you could be a PCBU as an individual.


If you run your business as part of a business partnership, you could each be individually and collectively a PCBU.


Larger corporations and organisations may have officers of the PCBU.


The legislation holds PCBU's to account “to ensure so far as far as reasonably practicable, the health and safety of workers and others” .

The Person Conducting a Business or Undertaking has the Primary Duty of Care

Under the new Work Health Safety Act, all PCBUs have a primary duty of care to ensure the health and safety of their workers and others who may be affected by the carrying out of work.

Where reasonably practicable, the PCBU needs to take action to eliminate risks to health and safety, or at the very least, ensure that those risks are minimised as far as is reasonably practicable.

This includes the strategic, structural, policy and key resourcing decisions involved in running the business.


Duties include:

  • "So far as reasonably practicable"

  • To create a safe workplace

  • Implement safe plan and structures

  • Implement safe work systems

  • Safe use handling and storage

  • Inform, train, and supervise

  • Adequate welfare facilities

  • Maintain and monitor

The PCBU's duty of care extends beyond physical care to psychological care.

Harsher Penalties for PCBU's

The new Work Health Safety Act includes a new offence of industrial manslaughter (s30A). This offence involves substantial penalties for PCBUs in a business where a WHS duty causes the death of an individual, in circumstances where the PCBU knew the conduct could cause death or serious harm.

The WHS Act voids insurance coverage for WHS penalties and imposes penalties for providing or purchasing this insurance.

The new laws also introduce what are known as enforceable undertakings, including:

  • If a business operates in a way that commits (or may commit) an offence under the WHS laws (except for industrial manslaughter or a Category 1 offence), they may be able to volunteer to give an enforceable undertaking instead of going through legal proceedings. Giving an enforceable undertaking is not an admission of guilt.


  • Their enforceable undertaking is a written commitment to do certain things in an agreed period, and can be accepted or rejected by the Regulator.


  • If the undertaking is accepted, the business would complete certain activities which need to be substantial and aim to deliver tangible benefits to the workplace, industry or broader community.


  • It is an offence to contravene an undertaking.

Industrial Manslaughter:

This provision began in Queensland, and is specifically a penalty for deaths.


This new offence is featured in Section 30A of the Work Health Safety Act 2020 (WA), and is relevant if the PCBU contravenes their duty of care, and it is established that their conduct causes death, or that it was known such conduct was likely to cause death.


The penalty ranges from $5million for individuals to $10million in penalties for corporations, with a possible maximum of 20 years imprisonment charge.

Reporting Requirements

Reporting requirements extend to ‘notifiable incidents’, which includes serious illness, injury or death and dangerous incidents which might happen during the conduct of a business or undertaking.


The WA Government has allocated funding for an extra 21 inspectors and six support staff to help improve WHS outcomes.


This also means that notifiable incidences could take place through spot checks, or through your organisation being dobbed in.


Regulators include:

  • The Australian Taxation Office

  • Fair Work Australia

  • Work Safe Australia
