History of the Telstra Research Laboratories


Open Days

TRL conducted open days in 1960, 1969, 1973, 1985 and 1997. In the earlier open days, months were spent preparing displays and there was unlimited money. Don’t know anything about the 1960 open day(s). The 1969, 1973 and 1985 open days each lasted a week. The1997 was one day and focused on the newly built display area in the auditorium. There was a wide variety of things to show in the early days. In particular, things that you could touch, bits that moved and spectacular visual shows such as the lightning display. The feedback from the public was tremendous. In the later days of TRL there was nothing much to show except displays on computer screens which was boring.

Scienceworks, run by museum Victoria, has many interesting visual and interactive displays. The lightning room contains high voltage equipment that was kindly donated by Telstra, following the closure of the lightning lab at TRL.
