Workplace safety, productivity, and well-being are essential to your business’s success.
In Queensland and Australia-wide, drug and alcohol misuse remains a significant risk factor across high-risk industries — and testing policies are one of the clearest, most defensible ways employers can meet their safety obligations.
This article covers when you can legally test in your business, why it matters, and how ATI’s HLTPAT010 Drug and Alcohol Testing course can help your business build that capability in-house.
The Cost of Substance Misuse to Australian Workplaces
Substance misuse carries a measurable cost, not just a safety one.
- Alcohol use alone is estimated to cost Australian workplaces around $4.0 billion annually, with absenteeism responsible for close to 90% of that figure.
- Illicit drug-related absenteeism adds a further $2.9 billion per year in lost productivity in workplaces nationally, across Australia.
- High-risk industries — construction, transport, mining, healthcare and manufacturing — carry disproportionate exposure, since impaired judgement and slower reaction times directly increase accident risk in safety-critical roles.
Beyond the direct productivity cost, substance-related incidents create legal, financial, and reputational exposure: workers’ compensation claims, potential fines under WHS legislation, insurance disputes where impairment contributed to an incident, and damage to client and community trust. Additionally, employees working alongside impaired colleagues may feel unsafe, unmotivated, or disrespected, leading to morale and retention challenges.
When Can You Conduct Drug and Alcohol Testing in Your Business?
Testing must be lawful, consistent, and clearly documented in policy to avoid claims of unfair treatment. In Queensland, employers can generally conduct testing under the following circumstances:
Pre-employment testing — as part of the hiring process, to confirm candidates meet safety and workplace standards before starting.
Random testing — common in safety-critical industries such as transport, construction, and mining, provided your policy clearly documents the process.
Post-incident testing — following a workplace accident or near-miss, to determine whether substance use was a contributing factor.
Reasonable suspicion testing — where an employee shows signs of impairment (erratic behaviour, slurred speech, smell of alcohol). Document the specific behaviour and reasoning to ensure the test is defensible.
Periodic testing — scheduled testing built into a business’s ongoing policy, often timed to the start of a major project or contract.
Return-to-work testing — as part of a documented rehabilitation or return-to-work agreement following treatment for substance misuse.
Why Drug and Alcohol Testing Policies Matter In the Workplace
Improved safety — identifying impairment before an employee undertakes high-risk tasks reduces the likelihood of accidents.
Workplace culture — a clear, consistently applied testing policy reduces the conflict, distrust, and morale issues that can arise when substance use goes unaddressed.
Enhanced Productivity – An unimpaired workplace fosters a culture of professionalism and focus, boosting team output and efficiency.
Legal compliance — under the Work Health and Safety Act 2011 (QLD), a person conducting a business or undertaking (PCBU) must ensure health and safety so far as is reasonably practicable. Specific industries, including transport, also operate under obligations set out in the Transport Operations (Road Use Management) Act 1995 (QLD). (Businesses should confirm current obligations against the latest legislation, as WHS regulation is periodically updated.)
Reputation and asset protection — a demonstrated commitment to safety supports trust with clients and insurers, and reduces risk to company vehicles, equipment, and other assets from impaired operation.
Train Your Team to Conduct Workplace Drug and Alcohol Testing and Improve Workplace Health and Safety
Drug and alcohol testing is a vital part of protecting your business, employees, and assets. By implementing clear policies, conducting lawful testing, and fostering a safety-focused culture, businesses can minimise risks and enhance productivity. Proactive measures not only ensure compliance with Queensland legislation but also protect your reputation, safeguard company vehicles, and create a safer workplace for all.
ATI’s Drug and Alcohol Testing Course (HLTPAT010 Collect Specimens for Drugs of Abuse Testing) — $525, available in Albion and Ipswich in Queensland or Online — trains your staff to conduct workplace testing correctly, consistently, and in line with current standards.
This is a practical option for businesses in construction, transport, mining, and other safety-critical sectors that want testing capability on-site rather than relying solely on third-party providers.
