Are workplace drug and alcohol testing programs legally permissible in Australia? In this comprehensive guide, we will explore the legal aspects surrounding workplace drug and alcohol testing in Australia, shed light on industries where testing is mandatory, and look into an employer’s responsibilities regarding reporting to the the NSW Police.

Mandatory Drug and Alcohol Testing

Drug and alcohol testing is mandatory in several industries to ensure workplace safety. The specific regulations and requirements for drug and alcohol testing may vary depending on the state or territory, industry, and job responsibilities. Here are some industries in Australia where drug and alcohol testing is commonly required:


Mining and Resources


The mining and resources sector in Australia often mandates drug and alcohol testing to maintain a safe working environment. This industry involves operating heavy machinery, working in remote locations, and handling hazardous materials. Ensuring sobriety is crucial to prevent accidents and injuries.


Transport and Logistics


The transport and logistics industry, including trucking, aviation, railways, and maritime sectors, generally have strict drug and alcohol testing policies. Employees in safety-sensitive roles, such as pilots, train drivers, and truck drivers, undergo testing to ensure they are not impaired while performing their duties.


Construction and Building


The construction industry in Australia usually requires drug and alcohol testing, especially for high-risk job roles. Construction sites involve operating heavy equipment, working at heights, and using power tools. Ensuring a drug- and alcohol-free workplace is critical to prevent accidents and promote safety.


Healthcare and Aged Care


In the healthcare and aged care sectors, drug and alcohol testing is often mandatory to safeguard patients’ well-being and ensure the quality of care. Healthcare professionals, including doctors, nurses, and caregivers, may undergo testing to maintain a safe and reliable environment for patients.


Defence and Emergency Services


The defence forces, police, and emergency services in Australia frequently implement drug and alcohol testing programs. These industries demand high levels of alertness, quick decision-making, and physical fitness. Ensuring personnel are free from substances that could impair their performance is crucial for public safety.

Random Drug and Alcohol Testing At Work

Onsite drug and alcohol testing is typically conducted randomly, selecting a group of employees within a specific timeframe. The main goal of this type of testing is to discourage employees from misusing drugs or alcohol. The employees are unaware of when or if they will be tested, which adds to the effectiveness of the deterrence.


An employer, has the right and authority to demand a drug test without prior notice, but only if there is a valid reason, which can be described as:


  • Aiming to enhance productivity within the workplace;
  • Concerns regarding potential health issues;
  • Maintaining the integrity of employees; and
  • Or ensuring workplace safety.

However, simply having a valid reason is not sufficient to carry out a drug test. It is also necessary to adhere to the guidelines stated in the business’s drug and alcohol policy, which include:


  • When a drug test may take place;
  • The specific type of drug test;
  • The utilisation of test results; and
  • And the company’s response to a positive test.

If the employer has suspicions that an employee is using drugs, they have the authority to take action based on their drug and alcohol policy. It is within their rights to ask an employee to undergo a drug or alcohol test, as long as the guidelines are clearly stated in their policy.


While employees do have the option to refuse a drug test, they may face disciplinary consequences as outlined in your workplace drug and alcohol policy. The company can argue that an employee’s refusal to comply with the request can be used as a valid reason for termination.


Therefore, it is crucial for the employers workplace drug and alcohol policy to explicitly state that if an employee declines a drug or alcohol test, it could potentially lead to their dismissal.

Does My Employer Have An Obligation To Inform The Police If I Fail a Drug Test?

No, your employer does not have an obligation to inform the police of a failed workplace drug test. If an employee tests positive for drugs at work, they will typically not face criminal consequences, but rather disciplinary measures or termination. Being intoxicated at hazardous workplaces can make employees more susceptible to accidents, potentially causing harm or even fatality.


However, if you or an employer hide information that could help a criminal investigation or the punishment of a wrongdoer, you could be charged and subsequently sentenced to a maximum of 2 years in prison according to section 316 of the Crimes Act 1900 (NSW). This rule only applies to information related to a “serious indictable offence,” which means an offence that can lead to a maximum of 5 years in prison.
