The Graduate Diploma in Engineering (Aerospace) is a postgraduate qualification designed to upskill engineering graduates and working engineers for advanced study and career opportunities in the aerospace sector. The program covers core aerospace engineering disciplines including applied aerodynamics, flight mechanics, space vehicle design, aircraft structures and materials, propulsion systems, and avionics — equipping students with both the theoretical foundations and applied technical skills needed to work across aviation, defence, and space industries. It is typically structured as a one-year full-time (or part-time equivalent) program and often serves as either a standalone qualification or a gateway to a Master of Engineering (Aerospace).

This qualification is suited to graduates who hold an undergraduate engineering degree — typically in mechanical, electrical, systems, or a related discipline — and who are looking to specialise in aerospace or transition into the field from adjacent engineering backgrounds. It also appeals to working engineers who wish to formalise or deepen their aerospace knowledge to advance their careers. The curriculum blends rigorous engineering science with industry-relevant design and problem-solving projects, often taught by research-active staff and practising industry engineers.

Graduates of this program are well-positioned to pursue careers across a diverse range of employers in Australia, including the Department of Defence, the Royal Australian Air Force (RAAF), Boeing Defence Australia, Airbus Australia Pacific, BAE Systems, Lockheed Martin Australia, Northrop Grumman Australia, Thales Australia, GE Aerospace, TAE Aerospace, Collins Aerospace, and a growing ecosystem of space startups and UAV manufacturers. Australia's national space agency and rapidly expanding domestic space sector also represent significant emerging employer pathways.

Applicants to a Graduate Diploma in Engineering (Aerospace) in Australia are typically required to hold a recognised bachelor's degree in engineering or a closely related technical discipline — such as mechanical, electrical, systems, civil, or physics — from an accredited Australian university or overseas equivalent. In some programs, applicants with a bachelor's degree in a non-engineering discipline may be considered if they have significant relevant industry experience. A minimum GPA or equivalent academic performance (commonly a Credit average or above) is usually expected, and recognition of prior learning and professional experience may be taken into account, particularly for working engineers seeking advanced standing or credit towards the qualification.

For international applicants and non-native English speakers, universities typically require demonstration of English language proficiency. Common minimum requirements include an IELTS overall score of 6.0–6.5 (with no individual band below 6.0), or equivalent scores in TOEFL iBT, PTE Academic, or Cambridge English examinations. Tests must generally have been completed within two years of the application date. Some institutions also consider prior completion of recognised English-medium study as an alternative to formal test scores.

Most programs do not require a portfolio, but applicants from non-engineering backgrounds may be assessed on relevant work experience, industry certifications, or professional memberships such as Engineers Australia Graduate Membership. Programs are predominantly offered as full-fee paying (FEE-HELP eligible for domestic students), and some may require Australian citizenship for access to defence-related electives or security-cleared industry placements. Intakes are typically offered in February (Semester 1) and July (Semester 2), though availability of specific programs in mid-year intakes varies.
