The JTA team, October 2025.
JTA has helped Australian workplaces manage health, safety and noise risks since 1988. Many of our people have been with JTA for years, and some for more than two decades. Their experience is behind every assessment, audit and report we deliver.
That experience is complemented by our Graduate Program. Science graduates spend 18 months working across our sales, safety, property and environment teams alongside our senior consultants, before moving into a permanent role in the area they choose to specialise in. It means the knowledge our team has built over decades is passed on to the next generation of health, safety and noise specialists.
Our consultants are also backed by a dedicated team of account managers and administration staff. Our account managers are your point of contact from the first quote to the final report, making sure each job is scoped to suit your site and your needs. Behind the scenes, our administration team coordinates bookings, equipment and paperwork, so our consultants can focus on the work and your reports arrive when you need them. Together with our ISO 9001 certified quality management system and NATA-accredited laboratory, it means you get accurate, reliable results and the personal service JTA was built on.
Want to build your career with JTA? We’re always looking for bright, talented people who are passionate about workplace health and safety.
