What this dot point is asking
NESA wants you to outline the development of Australian aeronautical engineering, identify major historical and current projects, and describe the current engineering capability supporting Qantas and the Royal Australian Air Force.
The answer
Historical context
Australian aeronautical engineering began in earnest during the Second World War. The Department of Aircraft Production ran two major manufacturing sites:
- Government Aircraft Factories (GAF) at Fishermans Bend (Melbourne), producing Beaufort and Beaufighter twin-engine combat aircraft for the RAF and RAAF during the war.
- Commonwealth Aircraft Corporation (CAC) at Port Melbourne and Avalon, producing the Wirraway trainer, Boomerang fighter, and post-war the Avon Sabre.
Combined wartime production peaked at over 30 aircraft per month and employed about 50{,}000 Australians.
Post-war projects
- CAC Avon Sabre (1953-1961). An indigenous adaptation of the F-86 Sabre with a Rolls-Royce Avon engine. 112 built; served with the RAAF and exported to Malaysia and Indonesia.
- GAF Nomad (1971-1985). A short take-off and landing twin-turboprop utility aircraft. 172 built; served with several civil and military operators. Programme cancelled in 1985 due to commercial difficulties.
- CAC CA-30 trainer (1980s). Failed competitive bid against the Pilatus PC-9. Australia bought PC-9s instead, but assembled them locally under Hawker de Havilland.
The GAF was privatised in 1987 (Hawker de Havilland) and merged with BAE Systems Australia in 1999. CAC was sold to Hawker de Havilland in 1985.
Current engineering capability
Australia now operates as a sustainment, modification, and component supplier rather than a prime aircraft manufacturer. The major activities:
Component manufacturing for Boeing.
- Boeing Aerostructures Australia (Fishermans Bend) builds 787 ailerons, leading edges and other moving surfaces.
- About 4 percent of every Boeing 787 by mass is built in Australia.
Component manufacturing for the F-35.
- BAE Systems Australia, Marand, Quickstep, Levett Engineering supply over 100 components.
- Vertical tail skins (Quickstep), vertical tails (Marand), wing tip components, weapon adapter, titanium structural fittings.
- About US$4 billion in contract value awarded between 2007 and 2026.
Qantas Engineering.
- On-wing maintenance, line maintenance, components and avionics repair at Sydney, Brisbane, Melbourne and Avalon.
- Major check facilities in Brisbane (heavy maintenance for 737 and A330).
- The Qantas-Boeing partnership covers component repair, supply chain and engineering data sharing for the 737, 787 and 747 fleets (the 747 retired in 2020).
Royal Australian Air Force sustainment.
- F/A-18F Super Hornet (Boeing), C-17A Globemaster III (Boeing), KC-30A MRTT (Airbus), P-8A Poseidon (Boeing), F-35A Lightning II (Lockheed Martin), C-130J Hercules (Lockheed Martin), MQ-4C Triton (Northrop Grumman), MQ-28 Ghost Bat (Boeing Defence Australia, the first Australian-designed and built combat aircraft since 1985).
Australia's manufacturing strengths
The current industry concentrates on:
- Composite manufacturing. Quickstep, Boeing Aerostructures Australia, RUAG.
- Precision machining. Marand, Ferra Engineering, Levett Engineering produce titanium and aluminium structural fittings.
- Software and avionics. CAE, BAE Systems Australia provide simulation and mission systems.
- Maintenance, repair and overhaul (MRO). Qantas Engineering, BAE Systems Australia, Honeywell Aerospace at Cherrybrook.
The MQ-28 Ghost Bat
The Boeing Australia MQ-28 Ghost Bat is the first Australian-designed and built combat aircraft since 1985. It is a 12 m wingspan unmanned uncrewed loyal wingman for the F-35 and Super Hornet, with composite airframe, electric backup actuation, and a swappable mission nose. The Ghost Bat marks the return of full aircraft engineering capability to Australia after a 40 year gap.
Industry significance
Australian aeronautical engineering supports about 25{,}000 jobs across manufacturing, MRO and software. The sector exports about A$1.5 billion per year and supports the Royal Australian Air Force's fleet readiness. The transition from indigenous prime manufacturing (Avon Sabre, Nomad) to component manufacturing and sustainment (787, F-35) reflects the global aerospace industry's consolidation around large primes (Boeing, Airbus, Lockheed Martin).

Australian aeronautical engineering grew from wartime domestic aircraft production and has since transitioned to sustainment, modification and component manufacturing.
- Historical project: the CAC Avon Sabre
- Built by the Commonwealth Aircraft Corporation at Fishermans Bend (1953-1961), the Avon Sabre was a re-engined redesign of the F-86. Australian engineers fitted a Rolls-Royce Avon turbojet, modified the airframe and intakes for higher flow, and replaced the guns with two 30 mm Aden cannons. 112 were built; it served the RAAF until 1971. The programme demonstrated indigenous airframe design, engine integration and combat aircraft production at scale.
- Current programme: F-35A Australian Industry Capability
- Australia is a Level 3 partner in the F-35 Lightning II programme. BAE Systems Australia, Marand, Quickstep Holdings and Levett Engineering build F-35 components including vertical tails, weapon adapters, composite skins and titanium machined parts for every F-35 worldwide (over 1000 aircraft delivered). The contracts exceed US$4 billion. Marand builds the vertical tails complete with control surfaces; Quickstep produces the carbon fibre skins. These are exported to the Lockheed Martin Fort Worth assembly plant.
- Civil capability
- Boeing Aerostructures Australia at Fishermans Bend builds Boeing 787 ailerons and flight control surfaces. Qantas Engineering provides on-wing maintenance and component repair under the Qantas-Boeing partnership.
Markers reward (1) a named historical project with engineering detail, (2) a named current programme with a supplier and component, (3) recognition of the shift from prime manufacturing to component manufacturing, and (4) Australian site or company names.
