Canberra

Canberra was the headquarters for UNIT in Australia. UNIT Canberra once sent a package to UNIT London for confirmation of its contents' alien origins. The artefacts were related to the 1930s yacht, Constitution III, that met its end reasonably close to Australia. The Third Doctor and Dr Liz Shaw confirmed the objects were alien soon after opening the package.

UNIT Canberra continued to supply UNIT London with assistance as the Doctor, the Brigadier, Liz, and Sergeants Yates and Benton investigated the origins of the artefacts further. (PROSE: The Eye of the Giant)

According to Tegan, Canberra was a city of "bold glass and concrete with sweeping curves and huge towers and clean roadways". (PROSE: Cold Fusion)
