QUEENSLAND – Gladstone Drug Testing

Peter Croskerry – General Manager

Having a background as a Chemist and Chemical Engineer has always had my interest in Chemical and Forensic processes. When the opportunity arose to purchase the Gladstone Region of The Drug Detection Agency (TDDA) Australia, I knew I could use my technical skills to help grow this region.

Gladstone was a green-field site and no one had heard of TDDA (or ADDA as it was known then). We have since developed and grown the brand identity of TDDA.

Within the Community we have offered advice and provided presentations to the Youth to raise their awareness of the dangers of drugs, both in Industry and the Community.

TDDA delivers a confidential service ranging from drug policy development, training / education and onsite drug testing in the workplace. Pre- Employment, Post Incident, Random Drug and Alcohol testing as well as Methamphetamine Detection for Property and vehicles. The mobile testing vans provide an innovative service to clients which delivers positive effects in the workplace with safety being a number one priority.

TDDA Gladstone is your local branch that specialises in all things drugs. We offer a 24/7 service of Post Incident testing, Pre-Employment testing, Reasonable Cause testing as well as Random Drug and Alcohol testing (D&A). With our custom fitted Mobile Vans, we can come to your offices or sites to conduct random D&A Testing (Urine and Oral Fluid), within the Gladstone Region. We also have a local office based at 124 Goondoon Street in Central Gladstone, where we have the facilities to carry out Pre-Employment testing without the need for an appointment. Just call to make sure a Collector is available. 

Using our office services, negates the need for Client employees to be held up in long queues at Medical Centres.

For random drug testing we can provide randomised computer generated lists of your staff members to allow Clients to be completely independent of the testing process and thus avoid any harassment claims.

We also offer a Meth Detection service for properties and also vehicles such as Trucks and Utes.
