de Havilland Aircraft Pty Ltd (DHA) — Australia's First Aviation Subsidiary and Wartime Manufacturing Powerhouse
de Havilland Aircraft Pty Ltd (DHA) was the first overseas subsidiary of the British aviation giant de Havilland, established in South Melbourne in March 1927. The company moved its core assembly, repair, and parts facilities to Bankstown, Sydney in 1930. While it began as an agency selling imported British aircraft, it grew into a major manufacturing powerhouse for the Royal Australian Air Force (RAAF) during and after World War II.
Today, through a chain of acquisitions, the company's legacy lives on as Boeing Aerostructures Australia.
Key Aircraft Produced
While de Havilland Australia originally assembled imported components, World War II forced the company into complete indigenous aircraft design and localised mass manufacturing:
DH.82 Tiger Moth
The primary basic trainer for Commonwealth forces during WWII. DHA manufactured nearly 1,100 of these biplanes at Bankstown, making it one of the largest single production runs of any Australian-built aircraft.
DH.98 Mosquito
A legendary twin-engine aircraft built from laminated timber. DHA overcame early quality control challenges to supply 212 wood-constructed fighter-bombers to the RAAF between 1943 and 1948 — a remarkable engineering achievement in the Australian climate.
DH.115 Vampire
The first jet aircraft ever built in Australia. DHA manufactured 190 of these composite wood-and-metal single-seat interceptors and two-seat jet trainers starting in 1948, marking Australia's entry into the jet age.
DHA-3 Drover
A unique, locally-designed three-engine light transport aircraft introduced in 1948 to replace the ageing pre-war DH.84 Dragon. Only 20 were built — most notably serving the iconic Royal Flying Doctor Service (RFDS).
Corporate Evolution & Legacy
The company's structural lineage traces directly into modern aerospace manufacturing:
| Era | Company Name | Key Milestones |
|---|---|---|
| 1927–1960 | de Havilland Aircraft Pty Ltd | Established as a sales agency, expanding into mass wartime production. |
| 1960–2000 | Hawker de Havilland (HdH) | Formed after the parent company was acquired by the Hawker Siddeley Group. Absorbed the Commonwealth Aircraft Corporation (CAC) in 1985. |
| 2000–2009 | Hawker de Havilland Aerospace | Purchased by The Boeing Company and merged with AeroSpace Technologies of Australia (ASTA). |
| 2009–Present | Boeing Aerostructures Australia | Renamed by Boeing; operates today as a primary exporter of Tier-1 composite components for commercial airliners. |
Diversity Into Marine Craft
In 1959, looking to leverage its extensive manufacturing capacity after post-war aviation demands slowed, the company opened a boat-building division at the Bankstown factory called de Havilland Marine. This division specialised in fabricating rugged, lightweight aluminium commercial vessels, workboats, and consumer runabouts — utilising the same metal-stress techniques perfected on high-performance aircraft hulls.
