Office Ergonomics: A Practical Guide for Australian Employers and OHS Teams

What the law actually requires

Most employers know vaguely that ergonomics is "an OHS thing." Far fewer know exactly which regulation creates the obligation.

The primary source is the Work Health and Safety Act 2011 (Cth), section 19: the primary duty of care to ensure the health, safety, and welfare of workers so far as is reasonably practicable. This captures physical environment, systems of work, and equipment. The Work Health and Safety Regulations 2017, Part 3.1, then specifically address hazardous manual tasks — defined to include any task requiring sustained or awkward postures, sustained application of force, or highly repetitive movement. Sedentary office work falls squarely within that definition when workstations are poorly configured.

Safe Work Australia's Code of Practice: Hazardous Manual Tasks(2022 edition) is the practical guide. It is not law, but courts treat non-compliance with an approved code as evidence that the employer did not meet the reasonably practicable standard.

For workers with a disability or recovering from injury, additional obligations arise under the Disability Discrimination Act 1992 (Cth), which requires reasonable adjustments to the workplace — including workstation modifications — as a condition of continued employment. Ignoring ergonomic accommodation requests in this context carries discrimination liability on top of the WHS exposure.

The five workstation variables that cause most injuries

Most office MSDs come from the same five sources. Get these right and you eliminate the majority of risk.

Running a defensible workstation assessment program

The goal is not just to fix chairs — it is to build a documented process that demonstrates due diligence if a claim arises.

1. 1

   1. Trigger-based assessment protocol

   Assess every new starter within their first week. Reassess on role change, equipment change, or within 5 business days of a reported discomfort. Set calendar reminders for 24-month reviews. Each of these triggers should be documented in your WHS management system.

2. 2

   2. Use a validated assessment tool

   The Rapid Office Strain Assessment (ROSA) and the RULA (Rapid Upper Limb Assessment) are both referenced in Safe Work Australia guidance. For workstation assessments, ROSA is preferred because it was specifically designed for office environments. Scores above 5 require immediate intervention.

3. 3

   3. Document corrective actions with timelines

   Every identified issue must have a named owner, a corrective action, and a completion date. "Monitor raised — completed 14 June 2026 — JM" is evidence. "Spoke to worker about chair" is not.

4. 4

   4. Separate equipment from behaviour

   Equipment fixes are necessary but not sufficient. Workers also need instruction on micro-break frequency (every 25–30 minutes), posture variation, and recognising early symptom warning signs. This is best delivered as a 15-minute induction module, not a PDF nobody reads.

5. 5

   5. Escalate complex cases

   If a worker reports persistent symptoms despite a corrected workstation, escalate to an Accredited Ergonomics Practitioner (AEP) or an occupational therapist. Complex cases involving return-to-work or disability accommodation should involve an occupational physician and be coordinated through your injury management program.

Hybrid and remote work: the assessment gap

The shift to hybrid work created a real compliance problem that most organisations have not resolved. The WHS duty does not stop at the office door.

Safe Work Australia confirmed in 2022 guidance that employers have WHS obligations for workers working from home, proportionate to the employer's ability to control the home environment. In practice, this means three things:

• ▸Remote workers should complete a self-assessment checklist (a validated tool like the DSE Self-Assessment, not a generic form) and submit it to their manager or OHS team.
• ▸Where a home assessment identifies a significant risk — for example, a worker using a dining chair for 8 hours a day — the employer must take reasonable steps to rectify it, which typically means funding appropriate equipment.
• ▸Employers who provide equipment to home-based workers retain control of that equipment and bear responsibility for ensuring it is fit for purpose.

Organisations with 50+ hybrid workers typically benefit from a digital self-assessment platform that captures responses, flags high-risk profiles, and auto-generates corrective action records — all without requiring an OHS officer to manually review every submission.

Sit-stand desks: what the evidence actually shows

Sit-stand desks have been heavily marketed as the solution to sedentary office work. The evidence is more nuanced than the sales pitch suggests.

A 2023 Cochrane review found that sit-stand desks moderately reduce sitting time (around 84 minutes per 8-hour day at 12 months) but showed limited evidence for meaningful improvements in musculoskeletal outcomes in isolation. The benefit is real, but it is the alternation of posture that matters, not the desk itself.

Practical implementation requires:

• ▸Anti-fatigue matting when the desk is in standing mode — standing on hard flooring for prolonged periods increases lower-limb loading
• ▸Monitor arm adjustment when transitioning between sitting and standing height — a fixed monitor becomes incorrectly positioned the moment the desk height changes
• ▸A recommended alternation schedule — evidence suggests 30–45 minutes sitting followed by 15–20 minutes standing as a target pattern
• ▸Worker education at the point of installation — desks left in the sitting position because nobody explained how to use them are not an intervention

When ergonomics intersects with injury management

Good ergonomics prevents injury. But it is also a core component of return to work.

Workers returning after a musculoskeletal injury — shoulder, neck, lower back, wrist — almost always require a modified workstation as part of their graduated return-to-work plan. The treating physiotherapist or occupational therapist may specify restrictions such as maximum continuous keyboard use, screen time limits, or a requirement for voice dictation software. The employer's WHS obligation is to implement those restrictions, not simply acknowledge them.

Practically, this means the person managing the workstation assessment and the person managing the return-to-work plan need to be talking to each other. In larger organisations, this coordination happens through the injury management framework. In smaller ones, it often falls through the cracks — which is how a three-week absence becomes a three-month claim.

Organisations that integrate ergonomics into their broader MSK injury management program — including pre-employment physical capability screening, early intervention physiotherapy, and structured return-to-work — consistently report lower claim durations and lower total claim costs than those treating each component in isolation.
