Drug and Alcohol Testing in Sydney
Workplace drug and alcohol testing across Sydney for pre-employment, random, and for-cause screening. On-site drug testing delivered at your workplace with results on the spot.
Why Workplace Drug Testing Matters
Maintaining a drug and alcohol-free workplace is a fundamental obligation under Australian Work Health and Safety legislation. Impairment from drugs or alcohol significantly increases the risk of workplace incidents, injuries, and fatalities — particularly in safety-critical industries such as construction, transport, and mining. A robust workplace drug testing program protects your workers, your business, and the general public.
Wellworx Workplace Solutions delivers onsite drug testing across Sydney — at your workplace, using both urine drug test and saliva drug test methods. Our testing is fully compliant with Australian Standards (AS/NZS 4308 for urine drug screening, AS 3547 for breath alcohol testing) and follows strict chain of custody procedures to ensure results are legally defensible.
Whether you need to screen new hires before they start, conduct random testing as part of your workplace policy, or respond to a for-cause or post-incident situation, we provide rapid on-site service with instant preliminary results. All non-negative results can be sent to an accredited laboratory for confirmatory analysis, maintaining full chain of custody documentation throughout.

How It Works
You tell us what you need

Frequently Asked Questions
What drugs are tested for in a workplace drug screen?
Standard workplace drug screening in Australia typically tests for amphetamines, methamphetamines, cannabis, opiates, cocaine, and benzodiazepines. The specific panel can be customised to your workplace policy requirements. All testing follows Australian Standard AS/NZS 4308 for urine screening.
How long do drug and alcohol test results take?
Preliminary results for both urine drug screening and breath alcohol testing are available on the spot - typically within 5-10 minutes. If a non-negative result requires confirmatory laboratory analysis, this can take approximately 3-7 business days depending on the laboratory.
Can an employee refuse a drug and alcohol test?
Whether an employee can refuse testing depends on your workplace policy and applicable legislation. In many safety-critical industries, drug and alcohol testing is a condition of employment. A clear, well-communicated workplace policy is essential. We recommend consulting your legal or HR advisor to confirm the specific requirements for your industry and jurisdiction.
What Australian Standards apply to workplace drug and alcohol testing?
Workplace urine drug screening in Australia is governed by AS/NZS 4308, and breath alcohol testing follows AS 3547. Our testing procedures are fully compliant with these standards, and we maintain chain of custody documentation for every test to support the legal defensibility of results.
