About Workplace Drug Testing Association

The Workplace Drug Testing Association (WDTA) was formally incorporated as a not-for-profit entity in early 2017 as the peak body representing the organisations and individuals involved in providing workplace drug testing services to the community.

This incorporation came about after a number of individual organisations recognised that the continued growth in the drug testing market, along with the challenges and opportunities arising from technological and scientific advances in the field of drug testing, would benefit from a collaborative approach to ensure the highest levels of integrity and professionalism are maintained in Australasia.”

Australasia’s Peak Industry Body for the Workplace Drug Testing Industry


Here’s what our happy members had to say about our services:

Royal Medical Supplies joined the WDTA due to frustration with the existing standards and relevant accreditation bodies. The WDTA is a welcome collective of highly experienced drug testing organisations and individuals and I highly recommend this association to anyone in the workplace drug testing industry.

Royal Medical Supplies Pty Ltd

We joined WDTA because we felt it was important to be part of a united industry body, promoting the interests of members for compliance and dealings with various government agencies. WDTA has quickly established a foothold in this regard with representation on various Australian Standards Committees and presentations to the Senate

Fit 4 Duty Pty Ltd

Safework Laboratories has been a member for the WDTA since its inception in 2017. We felt that there was a need to have an industry body that represented those organisations that do onsite workplace drug testing and SWL has been delighted to see the interest in our new association as well as the high profile it has achieved. In the short existence of the WDTA, it has been an influential advisor and committee member advising on new Australian Standards that are directly applicable to workplace drug testing, it has been asked to present to a Senate Enquiry as well other political events, but equally importantly it has provided a forum whereby those companies that work in this space can interact and work in a collaborative way to support and help each other on areas of mutual interest.
