Diploma in Modelling and Simulation of Chemical and Radiological Plumes — studying from Australia
Defence is one of Australia's largest engineering employers, with major programmes in land systems, naval platforms, aircraft and integrated systems managed through the Department of Defence. Land systems engineering supports armoured vehicles, weapons and logistics equipment, often through prime contractors and local industry partners. Industry involvement is strongly encouraged through the Defence industry policy framework. Engineers work on sustainment, capability development, systems integration and safety assurance, typically in Canberra, Adelaide, Melbourne and regional defence precincts.
Fees for Australia: A$2,050 (AUD), with instalments and employer sponsorship available.

Questions from Australia
How does defence engineering recognition work in Australia?
Defence engineering in Australia is largely run through the Department of Defence and its industry partners, which set their own security clearance and qualification requirements. Engineers Australia is the professional body for accreditation. SEIUM's private qualifications are not accredited by these bodies, so recognition is for employers or the relevant body to decide.
Which Australian employers hire in defence and land systems?
Australia has defence prime contractors, the Department of Defence, and specialist land systems firms. Many of these roles require Australian security clearances, which depend on citizenship and background checks rather than course completion. Ask employers how they weigh private qualifications against experience and clearance requirements.
Is the course manageable with a job, and does it need a visa?
The programmes are 100% online and taught in English, so you can study from Australia without a student visa. Specialist courses take 300 hours, diplomas 800 and master's 1,900. An assigned technical tutor supports you, fees are payable in instalments, and employer sponsorship may be possible.

How you'll learn
100% online learning on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so the programme fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is ALOHA, HYSPLIT, RASCAL, FLEXPART and JRODOS, in free, academic or evaluation versions. Practical work is based on real procedures: simulation of an industrial leak with ALOHA, comparison of Gaussian and Lagrangian models and analysis of a radiological emergency exercise. Assessment is continuous by module plus the final project.
Standards covered: NATO ATP-45, Directive 2013/59/Euratom, IAEA GSR Part 7, Directive 2012/18/EU Seveso III, Royal Decree 1564/2010, IAEA EPR-NPP Public Protective Actions 2013, AEGL and ERPG.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
