The model WHS Acts, Regulations and codes of practice tracked
as they move: what changed, who it binds and from when, each cited to the primary
instrument.
Person conducting a business or undertaking is what Australian WHS law hangs its primary
duty on, and we had used the term on most of this masthead without defining it. Section 5 in
full: the two-limb test, the reach into partnerships, and the four carve-outs, including a
volunteer-association exemption that ends as soon as the group employs one person.
The qualifying periods are near-identical nationally: brain cancer and leukaemia at five
years, bladder and kidney at fifteen. Whether a volunteer is covered is not. Tasmania,
Queensland, Victoria and the NT include them; WA, SA, the ACT and Comcare say employed
firefighters.
South Australia gives the injured worker 24 hours and their employer five business days.
Victoria gives 30 days. New Zealand allows 12 months. Queensland and Western Australia impose
no worker notification duty at all. Table 4.2, read scheme by scheme.
One national product standard, three different workplace regimes. Helmets and passenger
limits are regulated in Victoria, Queensland and Tasmania, a minimum rider age only in
Queensland, and everywhere else the obligation is the general duty plus guidance. From Safe
Work Australia's own consultation evidence.
Fair Work Act section 130 switches leave off while you are receiving compensation.
Queensland, WA, the ACT and Tasmania legislate past it, the Northern Territory scheme is
silent so the federal rule stands, and the Commonwealth schemes prohibit paid leave other
than maternity leave. Table 5.10, read scheme by scheme.
Part 3.1 binds only a PCBU with an express duty under the Regulations, and welding has
none, so it reaches the hierarchy of control sideways through hazardous chemicals. Six
welding-specific regulations are proposed; the first simply makes Part 3.1 apply.
Safe Work Australia had EY cost four proposed quad bike rules over ten years. Helmets
return $4.09 per dollar and a minimum age $4.20. Requiring operator protective devices on
every workplace machine returns $0.64, and the reason is the fleet already on farms, not
the devices.
The Digital Work Systems Act got assent on 18 February 2026 and puts algorithms, AI,
automation and online platforms inside the NSW WHS Act. Three provisions commenced, and
they are the ones that let SafeWork NSW write a guideline. The duties and the union
inspection power cannot start until a month after that guideline is published.
WHS ministers asked whether the model WHS Act should carry a new duty for crowd
platform operators. Fourteen submissions are published, and they turn on one question of
fact: how much control a platform has over the work. The consultation paper answers it
twice, differently.
Section 26A commenced 1 July 2026, making approved codes the minimum standard a PCBU is
expected to meet rather than admissible evidence. The word to re-read is
‘should’: in a code it is the standard, and the only lawful alternative is one
you can show is equivalent or higher.
It says so itself: it maintains the model WHS laws but does not regulate or enforce them.
Nothing binds until a jurisdiction implements it, every jurisdiction except Victoria has, and
most made variations. Who to actually deal with.
Ten submissions to Safe Work Australia's consultation, eight of them read in full. The
split is not the striking part: nearly every side began from the same admission that the
science could not settle the number, and reached opposite conclusions from it.
Safe Work Australia has opened a review of health and air monitoring for every hazardous
chemical, saying unclear requirements are holding monitoring rates down and that nobody knows
how far. Eleven issues, 26 options, and the Western Australian rule where the doctor sends
the report. Submissions close 21 September 2026.
Safe Work Australia opened a national consultation on Part 7.2 of the model
WHS Regulations, the lead regulations, conceding they may not be adequately protecting
workers. The three changes it put on the table, including a lower blood lead threshold
and health monitoring for every lead worker. Closed 24 August 2026.
Part 5 of the model WHS Act is machinery, not sentiment: section 48's four
requirements for real consultation, elected health and safety representatives
with a five-day paid training entitlement, the eight-day provisional
improvement notice, the cease-work direction, and a committee due within two
months of a request by five workers.
Regulation 39(3) requires safety information, training and instruction to
be readily understandable by any person who receives it: the legal hook for
multilingual workforces, varied literacy and young workers. The consultation
code's literacy expectations, and the November 2024 national guidance on
making the message land.
Regulation 42 requires equipment, facilities and an "adequate number" of
trained first aiders, scaled by the work, the hazards, the site and everyone on
it. The kit rules, the annual CPR refresher, the 200-worker first aid room line,
and the assessment that decides all of it.
Regulation 43 requires one written plan providing for response, evacuation,
notification, medical treatment and communication, built on the workplace's
actual hazards: fire, chemical release, natural disaster, bomb threats,
violence. The contents the law fixes, the 12-month drill benchmark, and who
coordinates the plan in a shared building.
Section 19 makes information, training, instruction and supervision one
duty with four working parts, regulation 39 sets the suitability test, the
white card guards construction's door, and Schedule 3 licenses 29 classes of
high risk work. What a PCBU must sight before work starts.
A safety management system is a loop, not a binder, and the law already
demands its working parts: officers must verify under section 27, workers
must be consulted under section 47. And the model Act defines corporate
culture, making a culture that tolerated a breach one way to prove a
company's fault.
The 18 kinds of high-risk construction work that demand a safe work
method statement before work starts, the $250,000 threshold that creates a
principal contractor and a site-wide WHS management plan, and the fatality
and claims numbers behind the machinery.
The 2025 national survey found 88.9 per cent of injured workers got back
to work, down from 91.6 in 2021; with a return-to-work plan the rate was
94.0 per cent, without one 81.7. The scheme duties, the coordinator role and
the measurable case for early intervention.
The WHS worker definition never asked how someone is engaged. Who owes what
to gig and labour-hire workers, why shared duties cannot be contracted away,
and the workers' compensation gap the October 2025 national policy approach is
trying to close.
Comcare's national audit tool puts 79 of its 108 criteria under
implementation: whether the system is used, not whether it is written down.
Where gap analysis fits, what ISO 45001 is and is not, and the officer duty
that makes verification a legal obligation.
Commencement dates from 2017 to 2024, maximum penalties from $10 million to
life imprisonment, and a model penalty that re-indexed days ago. The table every
multi-state duty holder needs, cited to each regulator.
The December 2025 incident notification amendment expands what PCBUs must tell
the regulator, once your jurisdiction adopts it. The current rules, the coming
ones, and a live example of the reporting loop working.
Two million workers, the worst claims record in the country, and a July 2025
code that says patient care never outranks worker safety. What aged care
providers now have to show.
One model law, nine implementations, one holdout state. What a PCBU is, what
officers owe, what codes of practice legally are, and what is about to change.
