QTEN
A curated network of senior specialists — formerly corporate leaders, expert witnesses, and advisory-level practitioners across engineering, environment, aviation, safety, AI, and the sciences.
QTEN is a selective network of Queensland's most experienced technical specialists — leaders who have led multidisciplinary programs, delivered expert witness testimony, held principal and chief-level positions in major corporations and agencies, and now bring that depth of experience to organisations that need it most.
We operate as a professional network, not a staffing agency. Our members are established independent practitioners and small firms who collaborate on complex, multidisciplinary challenges — delivering integrated advisory, investigation, design, and project delivery services with the rigour of a tier-one consultancy and the agility of an independent team.
