Aerospace engineering is the field of engineering concerned with the development of aircraft and spacecraft. The purpose of aerospace engineering is to achieve optimal integrated aerospace systems.

Amusement Rides and Devices Engineering deals with certification in accordance with the relevant Australian Standard, design, construction, operation, inspection, testing, service and maintenance associated with fixed and mobile amusement rides including work covered by AS3533Amusement Rides and Devices and Passenger Ropeways or similar covered by AS 4722:2018 and within the scope of CSA Z98-14. It is for engineers whose practice includes any aspect of amusement devices and passenger ropeways.

Asset management deals with the life cycle management of physical assets to meet specified outcomes and achieve the greatest return.

Biomedical engineering is the combination of design and problem solving engineering skills in applying engineering principles and design concepts to medicine and biology for healthcare purposes.

Building services engineering applies to the internal environmental and environmental impact of a building. Its purpose is to achieve optimal integrated building systems incorporating environmental control and safety provisions for the comfort and wellbeing of the occupants of the built environment.

Chemical engineering applies physical sciences (physics and chemistry) and life sciences (microbiology and biochemistry), together with applied mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy.

Civil engineering deals with the design, construction, and maintenance of the physical and naturally built environment. Civil engineers generally specialise in one of a number of sub-disciplines.

Construction Engineering is a professional service that utilises specialised, construction engineering techniques and technology to oversee the planning and construction activities from beginning to its end. The purpose is to coordinate and control construction processes and activities to meet the construction aims and objectives of time, cost, quality and safety to the required specifications and industry standards in a sustainable way.

Cost engineering is a niche discipline addressing the management of project costs and covers activities such as estimating, cost control, cost forecasting, investment appraisal, profitability analysis, project planning and scheduling.

Electrical engineering encompasses electricity generation, transmission, distribution, electrical equipment manufacture, instrumentation and control systems.

Environmental engineering creates innovative solutions for sustainable development. It is a very broad field in which there are new applications and adaptations of all the traditional disciplines of engineering.

Fire safety engineering is multidisciplinary having substantial relationships with building services, mechanical, electrical, electronics, chemical, structural and civil engineering and embraces an understanding of human behaviour. It is the application of engineering principles, rules and expert judgement based on a scientific appreciation of the fire phenomenon, of the effects of fire and of the reaction and behaviour of people.

Geotechnical Engineering deals with the mechanics of soil and rock and its applications to engineering elements. It deals with the analysis, design and construction of man-made structures or systems that are made of or are supported by soil or rock. They identify, design and implement practical solutions to engineering problems concerning soil, rock and groundwater. They apply scientific and engineering techniques to predict and manage the behaviour of the ground where it interacts with or responds to human activity.

Heritage and conservation engineering is an area of practice which requires applications and adaptations of all the traditional disciplines of engineering, together with an understanding of the elementary scientific principles involved which might not be directly referenced in current practice procedures. Practitioners will need to be aware of all the phases involved in conservation and the role of other professions, such as historians, archaeologists and architects.

Information, Telecommunications and Electronics Engineering (ITEE) applies scientific and engineering design to develop computer modelling tools, broadband capability, improve telecommunications systems, hardware and software, systems for media broadcasting and sound, and sophisticated electronics.

Leadership and Management is for engineering practitioners who hold management positions, where the majority of their day-to-day activities do not involve technical considerations.

Mechanical engineering applies the principles of engineering and physics with the study of advanced materials for the design, analysis, manufacturing, and maintenance of mechanical systems.

Mechatronics Engineering is multidisciplinary and deals with integrating electrical and mechanical systems. It can include a combination of robotics, electronics, computing, telecommunications, systems, control, product engineering, and electronics to create functional, smart products.

Naval Architecture is the safe design and specification of marine vessels and structures. The Naval Architect can also be involved in, or manage, the construction, repair, refit or operation of such marine vessels and structures.

Oil and Gas pipeline engineering centres on the efficient transport of fluids. This area of practice relates only to the transmission of petroleum and gas and related fluid pipelines.

Petroleum engineering falls into four main sub-disciplines which are reservoir, drilling, production, and formation evaluation engineering. The focus is on achieving optimal integrated exploration, technical assessment, production and development of oil, gas and geothermal resources and reserves upstream of processing plants, refineries and power stations.

Pressure equipment design verification is the process which assures the integrity of pressure vessels, boilers, pressure piping, and gas cylinders for the stated design and operating conditions.

Project management is the discipline of initiating, planning, executing, controlling, and closing the work of a team to achieve specific goals and meet specific success criteria.

Risk engineering is the application of engineering methodologies to the identification, analysis, assessment, control, and avoidance, minimisation, or elimination of unacceptable risks.

Structural engineering draws on engineering skills to understand, predict, and calculate the stability, strength and rigidity of built structures. Structures can include buildings, bridges, in-ground structures, footings, frameworks and space frames, including those for motor vehicles, space vehicles, ships, aeroplanes and cranes.

Subsea Engineering deals with the design, construction, installation, operation, maintenance and decommissioning of equipment in the ocean or on the seabed. Subsea engineers are engaged in managing activities throughout the asset lifecycle within various industries such as upstream oil and gas, marine/maritime and renewables.

Systems engineering is interdisciplinary, drawing on engineering and engineering management, focusing on how to design and manage complex systems over a system’s life cycle.
