Did you know that alcohol use contributes to 11% of workplace accidents and injuries in Australia? Additionally, alcohol-related absenteeism costs companies around $2 billion each year.
These statistics highlight the significant impact of substance use on workplace safety and productivity. To mitigate these risks, many Australian employers implement pre-employment drug and alcohol testing as part of their hiring process.
This proactive approach not only ensures a safer work environment but also aligns with legal and regulatory obligations. One of the most effective ways to maintain a safe and productive environment is through pre-employment drug and alcohol testing.

Many businesses, especially those in safety-sensitive industries, implement a testing program to screen potential employees for illicit drugs and blood alcohol levels before hiring.
This article explores the common methods of pre-employment drug tests, the legal framework surrounding them, and best practices for implementing a compliant pre-employment drug screening process.
Why pre-employment drug and alcohol testing matters
Conducting a pre-employment drug test is essential for several reasons:
- Workplace safety – Reducing the risk of accidents caused by drugs or alcohol.
- Compliance with industry regulations – Many sectors, including mining, transport, and construction, require mandatory testing.
- Risk mitigation – Preventing liability issues related to drug-related workplace incidents.
- Maintaining productivity – Ensuring a reliable and efficient workforce.
Legal requirements and compliance in Australia
Employers must adhere to strict legal guidelines when conducting a drug test in Australia. Under Work Health and Safety (WHS) laws, businesses have a duty of care to maintain a hazard-free workplace.
Certain industries, such as aviation, transport, and construction, have mandatory employment drug and alcohol testing policies to meet compliance requirements.
It’s crucial that employers obtain informed consent from each job applicant before testing. Additionally, results should preferably be reviewed by a Medical Review Officer (MRO) to ensure fairness and accuracy in the testing program.
Common pre-employment substance abuse testing methods
There are several drug testing methods used in pre-employment medical assessments, each with its own advantages:
- Urine drug test kits – The most common method of testing, requiring a urine sample to detect substances like THC, amphetamines, cocaine, opioids, and benzodiazepines. Urine tests from Andatech detect up to 15 different drugs and are widely used due to their cost-effectiveness and ability to detect drug use over a longer period.
- Saliva drug test kits – A less invasive method for detecting recent drug use, commonly used for roles requiring immediate screening.
- Alcohol testing via breathalysers – Measures blood alcohol concentration (BAC) to determine recent alcohol consumption.

Best practices for implementing a pre-employment drug testing program
To create a fair and effective pre-employment drug test policy, employers should:
- Clearly outline testing procedures – Establish a written policy detailing when and how tests will be conducted.
- Ensure compliance with privacy laws – Maintain confidentiality of results and inform candidates of their rights.
- Use accredited testing methods – Utilise urine drug tests, saliva tests, and breath alcohol screening that meet Australian standards.
- Provide support for employees – Implement an Employee Assistance Program (EAP) to help workers struggling with drugs or alcohol.
- Have a clear procedure for a positive result – Outline the steps taken when a candidate returns a positive result, including retesting, review by an MRO, and potential job implications.
Certain industries, such as aviation or logistics, have specialised drug and alcohol testing guidelines that are suited to the industry.

Challenges and considerations
- False positives – Certain medications or medical conditions can cause inaccurate test results, highlighting the need for an MRO to verify findings.
- Refusals to test – Employers must determine how to handle job applicants who refuse to provide a urine sample or participate in a drug screening.
- Legality of testing in different industries – Some sectors have stricter policies than others, so businesses should consult legal advisors if unsure about requirements.
