Aircraft Fleet
The TAA Douglas DC-4 was TAA's first four-engined airliner — and the aircraft that turned a young east-coast carrier into a genuine national one.
Fleet History
With the DC-3 fleet already carrying TAA's early services, the young airline set its sights further west. In July 1946, the Federal Treasury released £350,000 to allow TAA to order four larger, more modern DC-4s directly from the Douglas Aircraft Corporation in the United States.
General Manager Lester Brain appointed Aubrey Koch, formerly of Qantas, as Senior Pilot DC-4 Skymaster, and John Watkins as Chief Technical Officer. Watkins' first major assignment was to travel to the United States to oversee the acceptance, inspection and delivery of the new Skymasters — a role that would make him one of the key figures in TAA's early growth.
The first of the four DC-4s arrived in Australia in early October 1946 and flew its maiden TAA service — Melbourne to Perth — in November 1946. This aircraft was named John Eyre, after the explorer who pioneered the east–west crossing of the continent. The next three Skymasters continued the theme, christened Thomas Mitchell, John Forrest and McDougall Stuart. TAA kept naming its aircraft after Australian explorers for years afterward, with one notable exception: the Skymaster John Gould, named in October 1951 after the Australian ornithologist.

Service Entry
Where the TAA Douglas DC-3 had built TAA's east-coast network, the TAA Douglas DC-4 gave the airline something it didn't yet have: the range and capacity to fly coast to coast. With the Skymasters in service, TAA earned its title as a genuinely "trans-Australian" airline, offering services to Perth on the west coast to match its established eastern routes.

Technical Snapshot
Compared with the DC-3, the DC-4 was a significant step up in scale and sophistication — four engines instead of two, a longer cabin, and enough range to make Perth a same-day destination from Melbourne for the first time. TAA's engineering teams, already experienced from the DC-3 fleet, extended their maintenance standards to the new Skymasters as the airline's route network grew.
Legacy
The TAA Douglas DC-4's were gradually phased out of TAA's front-line passenger fleet through the 1950s as newer, pressurised aircraft like the DC-6 took over the airline's longer routes, though DC-4s continued in TAA service on other duties for some years after.
The TAA Douglas DC-4 is remembered as:
The Skymasters' brief but pivotal service marks the moment TAA stopped being simply an east-coast carrier and became the airline that connected the whole continent.
