Telecommunications in Australia

Telecommunications in Australia is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Telecommunications in Australia rather than just read about it. In short: Telecommunications in Australia refers to communication in Australia through electronic means, using devices such as telephone, television, radio or computer, and services such as the telephony and broadband networks. Telecommunications have always been important in Australia given the "tyranny of distance" with a dispersed population.

Reference excerpt

Telecommunications in Australia refers to communication in Australia through electronic means, using devices such as telephone, television, radio or computer, and services such as the telephony and broadband networks. Telecommunications have always been important in Australia given the "tyranny of distance" with a dispersed population. Governments have driven telecommunication development and have a key role in its regulation.

History

Colonial period

Prior to Federation of Australia in 1901, each of the six Australian colonies had its own telephony communications 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. Australia's first telephone service, connecting the Melbourne and South Melbourne offices of Robison Brothers, a Melbourne engineering firm, was launched in 1879. The private Melbourne Telephone Exchange Company opened Australia's first telephone exchange in August 1880. Around 7,757 calls were handled in 1884. The nature of the networks meant that regulation in Australia was undemanding: network personnel were government employees or agents, legislation was enhanced on an incremental basis and restrictions could be achieved through infrastructure. All the colonies ran their telegraph networks at a deficit through investment in infrastructure and subsidisation of regional access, generally with bipartisan support. Government-operated post office and telegraph networks – the largest parts of the bureaucracy – were combined into a single department in each colony on the model of the UK Post Office: South Australia in 1869, Victoria in 1870, Queensland in 1880 and New South Wales in 1893.

At Federation (1901) At Federation, the colonial networks (staff, switches, wires, handsets, buildings etc.) were transferred to the Commonwealth Postmaster-General's Department responsible for domestic postal, telephone and, telegraph services becoming the responsibility of the first Postmaster-General (PMG), a federal. With 16,000 staff (and assets of over £6 million) the PMG accounted for 80% of the new federal bureaucracy. Public phones were available in a handful of post offices. Subscriber telephones were initially restricted to major businesses, government agencies, institutions and wealthier residences. Eight million telegrams were sent that year over 43,000 miles of line. There were around 33,000 phones across Australia, with 7,502 telephone subscribers in inner Sydney and 4,800 in the Melbourne central business district. Overseas cable links to Australia remained in private hands, reflecting the realities of imperial politics, demands on the new government's resources, and perceptions of its responsibilities.

After Federation A trunk line between Melbourne (headquarters of the PMG Department) and Sydney was established in 1907, with extension to Adelaide in 1914, Brisbane in 1923, Perth in 1930 and Hobart in 1935.

On 12 July 1906 the first Australian wireless overseas messages were sent between Point Lonsdale, Victoria and Devonport, Tasmania. Australia and New Zealand ratified the 1906 Berlin Radio-telegraph Convention in 1907. The PMG department became responsible for some international shortwave services, particularly from the 1920s and for a new Coastal Radio Service in 1911, with the first of a network of stations operational in February 1912. The Sydney–Melbourne co-axial cable was officially opened on 9 April 1962. The coaxial cable infrastructure supported the introduction of subscriber trunk dialling between the cities and live television link-ups. After its commissioning in April 1962 the cable carried telegraph and telephone traffic. It also provided the first inter-city television transmission in Australia, allowing simultaneous television broadcasting in Melbourne and Sydney for the first time. Optus was formed as AUSSAT, a government owned corporation, in 1981. It was privatized later in the 1980s under the Hawke Labor government. Telstra (previously known as Telecom), another government owned asset, was also privatised in 1997 under the Howard Liberal government.

Broadcasting in Australia

Australia developed its own radio broadcasting system, through its own engineers, manufacturers, retailers, newspapers, entertainment services, and news agencies. Initially hobbyists and amateurs were dominant, however with the Commonwealth Government setting up the first radio system, and business interests becoming increasingly involved, hobbyists and amateurs were marginalised. The Australian Labor Party was especially interested in radio because it allowed them to bypass the newspapers, which were mostly controlled by their opposition. Both parties agreed on the need for a national system, and in 1932 set up the Australian Broadcasting Commission was set up as a government agency largely separate from political interference. The first commercial broadcasters, originally known as "B" class stations were on the air as early as 1925. Many were sponsored by newspapers in Australia, by theatrical interests, by amateur radio enthusiasts and radio retailers, and by retailers generally. Almost all Australians were within reach of a station by the 1930s, and the number of stations remained relatively stable through the post-war era. However, in the 1970s, the Labor government under Prime Minister Gough Whitlam commenced a broadcasting renaissance so that by the 1990s there were 50 different radio services available for groups based on tastes, languages, religion, or geography. The broadcasting system was largely deregulated in 1992, except that there were limits on foreign ownership and on monopolistic control. By 2000, 99 percent of Australians owned at least one television set, and averaged 20 hours a week watching it.

Worked examples

Example 1 — a first encounter with Telecommunications in Australia

Start with the simplest possible case. Write down what Telecommunications in Australia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Telecommunications in Australia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Telecommunications in Australia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Telecommunications in Australia

In research
Telecommunications in Australia appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Telecommunications in Australia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Telecommunications in Australia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Telecommunications in Australia, so understanding it makes those chapters shorter.
In everyday life
Look for Telecommunications in Australia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
