100 year anniversary of the automated Telephone Exchange
Filed under: consumer, exchange, history, innovation, technology
One hundred years ago this week, Geelong residents were the first in Australia able to direct dial a telephone call – no operator assistance needed! This amazing leap in technology was due to the installation of the first automated telephone exchange in the Southern Hemisphere and the second in the British Empire.
So cutting edge was the technology for its day, that the Geelong Advertiser wrote that “to see it work and grasp what it does makes it look supernatural” and it is “so ingenious as to almost beggar complete description”.
A few weeks after the launch, the Sydney Morning Herald reported on 23 July 1912, that “some of the subscribers have not yet mastered the new system of turning the discs round to secure the numerical combination for each subscriber dialled; but those who are able to operate the automatic system appear to be well satisfied.”
When I look at the technology Telstra’s networks support today it is hard to comprehend how far we have come in 100 years. If an automated telephone call looked supernatural, what would the writer think of the latest mobile handsets that make video calling possible, angry birds and words with friends are played by train commuters and where Google is a mere click away?
Australia has always been at the cutting edge of technology. From the first automated exchange in 1912, to launching innovative network solutions like Top Hats to extending fixed broadband coverage and to launching Australia’s first commercial 4G LTE network in September last year, Telstra has been there not only keeping our customers connected, but offering new and innovative ways to stay in touch.

I would be interested to see inside some modern exchanges to see the difference between then and now.
Any official photos inside modern exchanges?
how did telstra share the data 100yrs ago?
or was it illegal then too?
I worked for Telecom Australia Later known as Telstra from 1979 to 206. I worked on Step by Step, ARF Crossbar, ARF-C, AXE, System 12 & DMS during my years as a tech. It was a rewarding & enriching experience, while modern technology is amazing I still believe that the old electro mechanical switches held a certain romance, they we living machines which generated a certain smel fron the warm insulation & the oil & dag lubricants used. I have several photo’s of all technologies & some wave files of Step by Step.
Your comments are spot on. Well done. You should come to the Telstra Museum at Hawthorn Exchange and see a working SxS and ARF model. smells good too.
Of course Mr T Davis might be a little biased, he spent many a year at City West as well as managing Hawthorn Exch.
Geelong looks like the dustiest exchange in Australia, well, it was the first…… Reminds one of the good old days of the PMG which provided the Australian communications and with the latest technologies plus made nice profits which also subsidised the Australian Post Office and if it had been left to its own devices may well have provided the National Broadband Network in time to celebrate these 100 years as part of its normal operational costs.
Telstra should have BEEN the NBN and a new sales company created to sell the products be the telephone company
There is a vast difference, amongst other things ,you won’t see anyone wearing a suit and tie
The exchanges are all empty you will not find anyone in them at all.
