Postgraduate Diploma in TRIPOD/HFACS Methodologies and Evidence
The Postgraduate Diploma in TRIPOD/HFACS Methodologies and Evidence focuses on the study of risk analysis and human factors in the investigation of incidents and accidents. It explores the TRIPOD and HFACS (Human Factors Analysis and Classification System) methodologies to identify the root causes of adverse events, using evidence collection and data analysis for the prevention and mitigation of risks. The programme emphasises the application of these tools in operational safety, risk management and incident investigation, preparing professionals to identify failures and drive the continuous improvement of systems.
It addresses the importance of evidence, documentation and preservation in investigation, as well as the analysis of contributing factors, from failures in management systems to human errors. It provides skills for drafting effective investigation reports and implementing corrective measures. The postgraduate diploma is aimed at professional roles such as accident investigators, safety analysts, risk managers and aviation professionals, as well as professionals in other industries seeking to improve safety.
Postgraduate Diploma in TRIPOD/HFACS Methodologies and Evidence — studying from Australia
Health technology and biomechanics are growing areas in Australia, supported by a strong medical research sector and an established medical device industry. Wearable devices and occupational safety systems are increasingly used in mining, construction and healthcare. Medical devices are regulated nationally, requiring engineers to understand conformity, risk management and clinical evaluation. Employers include medical device manufacturers, hospitals, research institutes such as those affiliated with universities, and workplace safety consultancies.
Fees for Australia: A$2,050 (AUD), with instalments and employer sponsorship available.

Questions from Australia
Will a SEIUM qualification be recognised by Engineers Australia or other professional bodies for this area?
SEIUM qualifications are private qualifications and are not accredited by Engineers Australia or any other national body. Recognition is decided by individual employers and, where relevant, by the professional body assessing your application. Engineers Australia assesses skills and experience independently, so check directly with the body you hope to join before enrolling.
Which Australian employers might value this training in health, biomechanics or wearable safety work?
Employers in Australian medical device firms, rehabilitation services, workplace health and safety teams and wearable technology companies may consider advanced engineering training when hiring. Whether they value a private qualification depends on each employer's own policy and on your existing experience. Speaking with prospective employers about how they view private qualifications is a sensible step.
Can I study this alongside full-time work in Australia, and is employer funding possible?
The programmes are 100% online and taught in English, so you can study from any time zone, including Australian time zones, around your work hours. Fees are payable in instalments, and employer sponsorship is possible; ask your employer whether they fund training. Plan for the workload of 300 to 1,900 hours depending on the programme, and confirm the schedule with SEIUM.
