WESTERN AUSTRALIA – Kewdale Drug Testing

Sue Caswell – General Manager

Paul Crawford – Operations Manager​

Sue moved to WA from New Zealand in 2008, bringing with her an extensive background and comprehensive qualifications in occupational health and safety, quality assurance, human resources and general management.

Specialising in civil construction, with contracting stints in a range of other industries Sue can offer new and existing TDDA clients an empathetic and practical approach to the management of drug and alcohol policies, training and testing.

Joining Sue in the Kewdale region, Victoria Park to High Wycombe and metro wide, is Paul Crawford.

Paul spent in excess of 18 years in counter terrorism, policing and traffic in Northern Ireland before moving to WA. He initially took up a role with the Perth Transit Authority and then moved to the WA police. Extending his skills to include occupational health and safety management, Paul then worked for 6 years in mining in the Pilbara. The wide diversity of people and industries he has interacted with in his previous roles has enabled him to have a comprehensive understanding of the challenges, particularly with drug and alcohol use, abuse and management, and how the outcomes of poor choices of individuals effect the workplace and the wider community. With his primary focus being operations across the South Perth and Kewdale territories, Paul is also the franchisee for Kewdale.

Sue and Paul have a wealth of combined experience and qualifications which will add value to the effective running of your business.

We see almost daily reports of the meth crisis and the drug and alcohol fuelled violence in WA.
If it is happening in the community, it will be happening in the workplace!

Our office location is SOR, however with our fully self-contained, mobile testing vans we can go where you need us – 24/7.

Drug and alcohol testing, using urinalysis, oral fluid (saliva) or hair samples for workplaces, family court or pre-employment can all be offered at our office or via our mobile services.We are locally owned and operated and travel anywhere between Joondalup and Dawesville without charging mileage and if you need us to go into the Pilbara or other regions we can negotiate a fair and reasonable travel rate.

We specialise in drug and alcohol policy development, education and testing.
We have vast local and international expertise in health, safety, HR and law enforcement, most recently in the Perth metro and WA northwest.

Now as business owners ourselves, we can work efficiently and cost effectively with you to mitigate the risk, that drug and alcohol abuse is, to your organisation.

We know WA and we have colleagues interstate and in New Zealand if your organisation requires testing other than in Western Australia.
