Physical vs Psychological Injuries
While physical injuries have traditionally dominated workplace safety, psychological injuries are now recognised as causing greater individual harm, higher costs, and longer recovery times. The data makes a compelling case for equal — if not greater — focus on psychosocial risks.
The Hidden Epidemic
Psychological injuries represent approximately 10% of all workers' compensation claims in Australia, but account for 30% of total costs and involve significantly longer time off work. The gap between physical and psychological injury outcomes continues to widen.

The Hidden Costs
Workers' compensation data only captures a fraction of the true cost of poor psychosocial safety. The most significant costs are often invisible in traditional reporting:
Presenteeism
Workers experiencing psychological distress who remain at work but operate at reduced capacity. Studies estimate presenteeism costs 2-3× more than absenteeism for mental health conditions.

Turnover
Psychosocial hazards are a leading driver of voluntary turnover. Replacing an employee costs 50-200% of their annual salary. Organisations with poor psychosocial safety climates experience significantly higher turnover rates.

Reputational damage
High-profile psychosocial safety failures — bullying scandals, harassment cases, or toxic culture reports — cause lasting reputational harm that affects recruitment, client relationships, and shareholder confidence.

Litigation and regulatory penalties
Beyond workers' compensation, organisations face civil litigation, regulatory prosecution, and fines. Individual officers can face personal liability including fines up to $600,000 and imprisonment.

Insurance premium increases
Increasing psychological injury claims drive up workers' compensation premiums. Some insurers are introducing psychosocial risk assessments as part of underwriting.

Team and cultural impact
Psychosocial hazards rarely affect individuals in isolation. Poor management practices, bullying, or unreasonable demands create ripple effects that degrade team cohesion, trust, and collective performance.

The Regulatory Shift
Historically, workplace safety regulation was built around physical hazards — machinery, chemicals, falls, and manual handling. Psychological injuries were often dismissed as personal issues unrelated to work. This paradigm is fundamentally changing.
The 2022 amendments to Australia's model WHS Regulations placed psychosocial hazards on the same regulatory footing as physical hazards. This means employers must apply the same systematic risk management approach — identify, assess, control, and review — to psychosocial risks as they do to physical risks.
Critically, the duty is proactive. It is not sufficient to respond to psychological injuries after they occur. Employers must take reasonable steps to prevent exposure to psychosocial hazards. This requires ongoing monitoring, consultation with workers, and a genuine commitment to managing the design and organisation of work — not just providing an Employee Assistance Program (EAP).
"An EAP is not a control measure for psychosocial hazards. It is a support service for workers who are already experiencing harm."
