What Is a Coal Board Medical?
A Coal Board Medical (CBM) — sometimes referred to as a coal mine medical or coal worker health assessment — is a standardised occupational health examination required for workers employed in coal mining operations in Australia. The assessment is designed to establish a baseline health record for workers entering the industry and to identify any pre-existing conditions that may be exacerbated by coal dust exposure or the physical demands of underground or open-cut mining.
The medical is named after the Coal Mining Industry (Long Service Leave) Administration Act provisions and industry-specific health surveillance requirements that were historically administered by state Coal Boards. While Coal Boards in the traditional sense no longer exist in most states, the term "Coal Board Medical" persists as industry shorthand for the standardised assessment required for coal mining employment.
In Queensland, the most coal-intensive state, the requirements are codified under the Coal Mining Safety and Health Act 1999 and associated regulations. Similar requirements apply in NSW under the Mine Safety Legislation. The medical must be conducted by an approved occupational physician or occupational health service — not a GP.
Unlike a standard pre-employment medical, a Coal Board Medical includes specific respiratory and audiometric testing intended to detect the early effects of dust and noise exposure — two of the most significant occupational hazards in coal mining. Results are entered into the employee's health surveillance record and may be reviewed against future assessments to detect any deterioration over time.
Who Needs a Coal Board Medical?
A Coal Board Medical is required for anyone taking up employment in a coal mine in Australia, including:
- Underground miners — direct coal face workers, longwall operators, development miners
- Open-cut operators — dragline operators, excavator operators, truck drivers on coal operations
- Maintenance and trade workers — electricians, fitters, boilermakers permanently based on coal mine sites
- FIFO contractors on coal mine sites for extended periods
- Mine supervisors and management who enter coal mine environments regularly
Short-term visitors, surface-only administrative staff, and workers on adjacent construction projects who do not enter the mining environment may not require a full Coal Board Medical — check with the site's site senior executive or occupational health team to confirm the requirement for your specific role.
Workers already employed in coal mining are subject to periodic health surveillance — typically every five years, or more frequently if the initial assessment reveals a heightened risk profile. The periodic review follows the same testing protocol as the initial CBM.
Tests Included in a Coal Board Medical
A full Coal Board Medical encompasses several component assessments. The total appointment typically takes two to three hours depending on the clinic and the number of components required.
Spirometry (Lung Function Test)
Spirometry measures lung capacity and airflow — key indicators of respiratory health for workers exposed to coal dust. You will breathe into a mouthpiece connected to a spirometer, which records FEV1 (forced expiratory volume in 1 second) and FVC (forced vital capacity). Workers with significantly reduced lung function may be restricted from underground coal environments.
Audiometry (Hearing Test)
Audiometry establishes a baseline hearing profile for workers entering a high-noise environment. Coal mines are among the noisiest workplaces in Australia, and noise-induced hearing loss (NIHL) is a significant occupational hazard. The audiometry conducted at the CBM creates the benchmark against which future periodic assessments are compared to detect hearing deterioration.
Musculoskeletal Assessment
Coal mining involves significant physical demands — manual handling, vibration exposure from heavy machinery, and awkward postures in confined underground spaces. The musculoskeletal component assesses range of motion, strength, and any pre-existing injuries or conditions that may limit safe task performance or be aggravated by mining work.
Drug and Alcohol Screen
A urine drug screen is included in all Coal Board Medicals and tests for the standard Australian panel of substances (cannabis, amphetamines, opioids, cocaine, benzodiazepines). Breath alcohol testing is typically also performed. A positive drug screen will result in the medical being placed on hold pending confirmation testing.
Vision and Cardiovascular Assessment
Visual acuity and colour vision are tested as part of the CBM — operators of heavy mining equipment require adequate vision standards. Blood pressure, resting ECG, and general cardiovascular assessment are included for workers aged over 45 or in roles with specific cardiovascular demands. A blood test may be required in some circumstances.
Coal Board Medical Costs
The cost of a Coal Board Medical in Australia varies depending on the clinic, state, and whether the assessment is self-funded or employer-funded. Typical pricing ranges:
- Standard CBM (full assessment): $300–$450 AUD
- Periodic review (existing coal workers): $250–$380 AUD
- With additional components (ECG, blood tests): $380–$550 AUD
Most major mining employers and labour hire firms pay for the Coal Board Medical as a pre-employment cost. Contractors who arrange their own CBM and present the result may be reimbursed by the hirer — clarify this with your employer or engagement party before booking.
Medicare does not cover Coal Board Medical assessments. These are occupational health assessments, not general health consultations, and must be funded by the employer or candidate.
How to Book a Coal Board Medical
Coal Board Medicals must be conducted by a clinic with an occupational physician or nurse practitioner approved to conduct mining health assessments. The most widely used providers in Australia include Sonic HealthPlus (with clinics in all major mining regions), Resmed Workplace Health, and state-specific mining medical providers.
To book:
- Confirm with your employer or labour hire firm whether they have a preferred clinic or account. Using the employer's preferred provider may reduce your cost or allow direct billing.
- Call or book online with the clinic, specifying that you need a "Coal Board Medical" or "pre-employment mining medical" for a coal operation. Specify the state/territory of the operation — this may affect which protocol the clinic follows.
- Fast before the appointment if a blood test component is likely (your booking confirmation will specify).
- Bring government-issued photo ID, your Medicare card, and any relevant medical history (particularly respiratory conditions, hearing aids, or orthopaedic history).
- Disclose any prescribed medications to the clinic before the appointment — this is critical for the drug screen component.
Refchecks can coordinate Coal Board Medical bookings through its Sonic HealthPlus integration, allowing employers to initiate the booking as part of the onboarding workflow.
How Long Is a Coal Board Medical Valid?
A Coal Board Medical is valid for two years for initial assessments, after which periodic health surveillance is required. Some site-specific requirements or contractor agreements stipulate annual renewals, particularly for workers over 50 or those with flagged health conditions in their initial assessment.
Workers who leave the coal mining industry and return after more than two years will typically need a fresh CBM before site access is granted. Workers moving between different coal operations are generally accepted on the basis of an existing valid CBM from another site, provided the assessment was conducted at an approved clinic.
Always check site-specific requirements with the site's health and safety team — the validity period enforced on-site may be more conservative than the regulatory minimum.
