Telstra Museum
This museum contains a comprehensive collection of telecommunications equipment dating from the late 1880s to the present. This includes displays relevant to telephones, switchboards (telephone exchange and business), Morse code, and teleprinters (Telex machines). Under each of these categories we have working examples which visitors are welcome to operate if they so desire, and all our guides have expertise in this equipment dating back to their working days. In fact the experience of these guides between them covers just about all aspects of PMG/Telecom/Telstra and Australia Post operations since the early 1940s.
