Almost every article on the internet about Australian workplace safety law is about the Work Health and Safety Act. If you work on a Queensland mine, almost every one of them is about a law that does not govern your site.
That is not a technicality. The duty holders have different names, the reporting categories are different, the enforcement instruments are different, and since June 2026 there is an obligation with no WHS Act equivalent at all.
Which Act governs what
Queensland runs two pieces of resources safety legislation:
- The Coal Mining Safety and Health Act 1999 (CMSHA), with the Coal Mining Safety and Health Regulation 2017 under it — coal mines.
- The Mining and Quarrying Safety and Health Act 1999 (MQSHA), with the Mining and Quarrying Safety and Health Regulation 2017 — mineral mines and quarries.
The regulator is Resources Safety and Health Queensland (RSHQ), not WorkSafe Queensland.
When the model WHS laws were harmonised across Australia from 2011, Queensland kept these two Acts outside the model. Western Australia went the other way and folded resources into its Work Health and Safety Act 2020 (WA) from 31 March 2022, with a mining-specific regulation under it. New South Wales runs a hybrid: the WHS Act applies, with the Work Health and Safety (Mines and Petroleum Sites) Act 2013 layered over it.
So three of the big resources states arrived at three different structures. If you operate across them, you are managing three frameworks, not one.
Who holds the duty
The WHS Act's central concept is the PCBU — the person conducting a business or undertaking. The Queensland mining Acts do not use it. They name obligation holders individually.
The operator. The entity that operates the mine, with overarching obligations for the safety and health management system.
The site senior executive (SSE). This is the role with no real WHS Act counterpart, and it is the one contracting companies most need to understand. The SSE is appointed by the operator and holds personal statutory obligations for the safety and health of everyone at the mine — including every contracting company's worker. They must develop and implement the safety and health management system, ensure risk is at an acceptable level, and ensure that people at the mine are competent to do what they are being asked to do.
That last obligation is the reason a Queensland mine's contracting company requirements can look heavy-handed. The SSE is personally accountable for the competency of your team on their site. They cannot delegate it to your assurance that everyone is fine.
Supervisors, coal mine workers and contracting companies each carry their own duties. Suppliers of plant and substances do too.
Site safety and health representatives and industry safety and health representatives hold statutory powers, including the ability to issue certain directives. The industry representative role — elected, funded by industry, with a right of entry and inspection powers — has no direct WHS Act equivalent and is a genuine feature of the Queensland system.
"Acceptable level of risk"
Where the WHS Act says "so far as is reasonably practicable", the Queensland mining Acts say risk must be at an acceptable level.
The Acts define it: risk is at an acceptable level when the likelihood of injury or illness is within acceptable limits, and the risk is as low as reasonably achievable. It reaches broadly similar territory to the WHS test, by a different route and with a different centre of gravity — "as low as reasonably achievable" reads as more demanding than "reasonably practicable" to most people who have to apply both.
What changed on 1 June 2026
The Resources Safety and Health Legislation Amendment Act 2024 is the most significant change to Queensland resources safety law in years. Its critical control provisions commenced on 1 June 2025, with a one-year transition, making compliance mandatory from 1 June 2026.
What it requires, in substance:
Identify the material unwanted events (MUEs). The events that could kill or seriously harm people — fires, explosions, inrush, structural failure, vehicle interaction, and the rest of the site's fatal-risk list.
Identify the critical controls. For each MUE, the specific controls that prevent it or mitigate its consequences. Not every control. The ones whose failure would materially change the outcome.
Embed critical control management into the safety and health management system, with a systematic and verifiable approach to assuring those controls are effective.
The word doing the work is verifiable. The obligation is not to have controls, or to believe they are working. It is to be able to show, systematically, that they were.
The same Act removed prescribed specific notifiable incident types from the legislation, which shifts reporting further onto a site's own judgement about potential consequence rather than onto a list to check against.
Why this reaches contracting companies directly
Critical controls are performed by people, using plant. A control is only actually in place if:
- the person performing it is competent to perform it; and
- the equipment involved is fit for the task.
On a contracting company-heavy site — which is most Queensland mines — a large share of the people performing critical controls, and a large share of the plant, belongs to contracting companies. So an operator that has to verify its critical controls has to verify your workers' competencies and your machines' condition.
Verification, not attestation. The distinction is the entire point of the change. A contracting company's signed statement that everyone holds what they should is an attestation. A record that shows this named person held this named competency, assessed on this date, and this named machine was serviced on that date, is verification.
That is why contracting companies are experiencing 2026 as a year in which client requirements got noticeably heavier and more specific, often without a clear explanation of why. This is the why.
Reporting: high potential incidents
Queensland mines do not report "notifiable incidents". They report:
- deaths;
- serious accidents;
- high potential incidents (HPIs); and
- reportable disease.
A high potential incident is an event, or a series of events, that causes or has the potential to cause a significant adverse effect on the safety or health of a person. It is defined by potential rather than by an enumerated list — which makes it broader than the WHS Act's "dangerous incident" categories, and more a matter of judgement.
RSHQ has issued a safety notice to industry about under-reporting of high potential incidents. Where a call is marginal, that is the regulator telling you which way to err.
Competency requirements you will actually meet
The obligations above produce a set of very concrete requirements at the gate. For a Queensland coal mine, the recurring ones are:
- Standard 11 — the recognised generic safety and health induction for coal mine workers, delivered as an accredited skill set and refreshed on a five-year cycle, plus site-specific and task-specific induction on top.
- Coal mine workers' health assessment (formerly known as the coal board medical) — required under the Coal Mine Workers' Health Scheme on entry to the industry and at least every five years, conducted or supervised by an Appointed Medical Adviser from the RSHQ-approved list.
- Statutory positions and high risk work licences where the task requires them.
- Verification of competency (VOC) for the specific tasks and plant a worker will actually be doing on that site.
Each has its own guide on this site, because each is asked about separately and each has details that trip people up.
If you work across the border
The most common failure we see is not ignorance of Queensland's law. It is a business that knows the WHS Act well, applies it consistently, and does not realise that its Queensland mining work sits outside it.
The symptoms are recognisable: an incident procedure that says "notify within 48 hours" when the mining Act's obligation is immediate and verbal; a document that talks about improvement notices on a site where the instrument is a directive; a contractor management process built around a PCBU model on a site where the SSE holds a personal obligation for your people's competency.
None of those are catastrophic on a normal day. All of them are the wrong answer on the day it matters.
