| AUSTRALIAN TELECOMMUNICATIONS EVENTS | |
|---|---|
| HISTORICAL PERIOD | DISCUSSION |
| the colonial period | Telecommunications in Australia began in 1854 with a telegraph line from Melbourne city to Williamstown, publicly funded but privately constructed (like South Australia's first line in 1856 from Port Adelaide to Adelaide city). At that time there were over 23,000 miles of line in the US (up from 12,000 miles in 1850, 2,000 in 1848 and 40 in 1846). |
| first telephony | For the first fifty years of its existence most people in Australia experienced telecommunications through telegraphy even where the telephone was available. It was thus at second hand, rather than directly person-to-person. That experience often involved couriers, with a 'telegraph boy' for example delivering a handwritten or printed message to a residence, business or other location. It also involved use of official post offices and agencies, with individuals for example visiting an office and writing the message on a form which was then keyed for transmission to the desired destination. Messages were charged on a character by character basis and on the basis of distance, resulting in 'telegraphese' (truncated spelling and grammar that was a precursor of texting). |
| shape of the network | The Australian networks were government assets operating under colonial legislation modelled on that of Britain. The UK Telegraph Act 1868 for example empowered the Postmaster General to "acquire, maintain and work electric telegraphs" and foreshadowed the 1870 nationalisation of competing British telegraph companies. The nature of the networks meant that regulation in Australia was unchallenging -
|
| federation | Section 51(v) of the 1901 Australian Constitution gave the new national government power over all postal, telegraphic, telephonic and 'other like services'. The latter encompassed future developments such as radio, television and the internet. The colonial networks (staff, switches, wires, handsets, buildings etc) were transferred to the Commonwealth and became the responsibility of the first Postmaster-General (PMG), a federal Minister overseeing the Postmaster-General's Department that managed all domestic telephone, telegraph and postal services. With 16,000 staff (and assets of over £6 million) it accounted for 90% of the new federal bureaucracy. That figure climbed to over 120,000 staff (around 50% of the federal bureaucracy) by the late sixties. At the time of federation it would have been appropriate to speak of a 'telephone divide'. Public phones were available in a handful of post offices and otherwise restricted to major businesses, government agencies, institutions and wealthier residences. Eight million telegrams were sent that year over 43,000 miles of line. (In the UK there were around 89 million messages.) |
| radio and picturegrams | A public radio-telephone service between Australia and New Zealand commenced on 25 November 1930. In July of the following year that was linked to the UK-Australia radio-telephone service, which utilised beam wireless stations in Victoria at
Fiskville and Rockbank. Those stations were opened in 1927 by Amalgamated Wireless Australasia (AWA). The company was an electrical conglomerate - the Australian equivalent of General Electric in the US - with interests extending from radio receiver manufacture to operation of commercial broadcasting stations. The two stations were primarily concerned with radiotelegraph traffic. Facsimile services were introduced in the late 1920s, using the Siemens-Karolus picturegram system. Images were of low quality and transmission was slow and expensive, so that most traffic appears to have related to low resolution reproduction in newspapers of photographs and cartoons. In Australia the first photographs were transmitted between Sydney and Melbourne in 1929, with the first radio-picturegrams from London received in Melbourne in 1934. Equipment at that time was only available at PMG premises or those of its agents such as AWA. |
| consolidation | By 1939 Australia was 7th in the world teledensity ranking, with all capital cities except Darwin connected through a national network of 'voice grade' lines and 50% of services through automatic exchanges (significantly better than the UK and most of continental Europe). It has remained in the top ten and as current statistics suggest it has a greater per capita number of mobile phones than the UK and US. A public telex (teleprinter) service was available in Australia from 1954. Transmissions of picturegrams between PMG sites peaked at 6,280 in 1958, declining as individual media organisations, news services such as Australian Associated Press and a handful of industrial companies such as BHP installed their own picturegram equipment. Both the teleprinter and picturegram services were superseded in the 1970s as 'wet' and later plain paper facsimile machines became available. Those devices did not require special training or a dedicated line. In 1975 telecommunication regulation and delivery was restructured, with PMG handling all postal services, OTC retaining responsibility for international telecommunications and the Australian Telecommunication Commission (trading as Telecom Australia) being established to provide public telecommunication services within Australia. |
| the emergence of data networks | Throughout most of Australia's history the dominant infrastructure model was that of a publicly owned network centred on the transmission of telegraphic and voice traffic rather than digital data. Telephone handsets were owned by the network operator, rather than by the subscriber, and in an echo of Henry Ford's quip about the Model T came in any colour as long as that was black. From the 1960s, as mainframes became increasingly affordable (whether on a purchased, leased or time-shared basis), there was growing public and private sector demand for domestic and international data exchange. In 1973 around 2,500 modems were in use; that figure grew throughout the decade. Declining infrastructure costs outpaced reductions in establishment fees and ongoing maintenance charges by the PMG, leading some major consumers such as the television networks to explore loopholes in the legislation that would enable creation of dedicated private networks (eg high-capacity microwave links between stations and television transmitters in NSW). Such moves were reflected in uptake of private facsimile machines throughout the 1980s: by 1993 the number of machines in Australia had grown to around 360,000. Faced with demands from domestic and commercial users for lower prices and better access to the network (from the early 1970s most Australian households expected to have a fixed line phone) the monopoly network operator in Australia adopted two strategies. One was to roll out basic infrastructure across the nation, minimising investment through technical compromises in the location of exchanges and use of twisted pair connections to households. Those compromises meant that much of the network in place at 2003 was unsuitable for ADSL. Upgrading to broadband was not possible without significant investment (unlikely given demands to raise revenue and profitability in a competitive environment). A second strategy was an acknowledgement that all customers were not equal and that commercial customers - in particular major organisations - both could and would pay a premium for a higher quality of service based on enhanced infrastructure. One example in the 1970s was the PMG's Common User Data Network (CUDN), a packet-switching scheme allowing simultaneous access by multiple users for the exchange of information between computers and featuring a primitive electronic mail system. |
