Australia Post Codes & Zip Codes List

Postcodes in Australia

Postcodes in Australia are four digits long and appear after the country in the address. Postcodes were introduced by Australia Post Service in 1967. The Postmaster-Department now manages them. Australia Postcodes help to sort and route mail more efficiently in Australia. Australian envelopes and postcards often have four orange square boxes for the postcode. These help with the automated sorting of hand-addressed mail for Australian delivery.

History Of Australia Postcode

The Postmaster-(PMG) General in Australia introduced the postcode system in 1967 to replace earlier postal sorting systems like Melbourne's letter and number codes and a similar system used in rural and regional New South Wales. Postcodes were introduced at the same time as Australia's first large-scale mechanical mail sorting system, at the Sydney GPO.

By 1968, 75% of mail had a postcode, and the post office introduced preferred-size envelopes, dubbed "standard envelopes." To help Australia Post's mail sorting machines sort mail by postcode, postcode squares were introduced in June 1990.

Australia Postcode Format

All Australian postcodes always consist of four numbers. You can always locate them after by the city, suburb, or town's name and the state or territory. However, if an address is written on an envelope, the postcode may be written instead of a street address in a row of four boxes. When mailing to a business, the recipient's name may be substituted. An article's identity can be prefixed on the line above the business name, followed by c/-. The postcode comes before the word 'Australia' on the fourth line.

Australia Postcode Geography

Postcodes in Australia help sort data. They are frequently linked to a single theme (e.g. 6160 belongs only to Fremantle, Western Australia). Postcode rationalisation can make them complex, especially in rural areas (e.g. 2570 belongs to twenty-two towns and suburbs around Camden, New South Wales).

The Geelong Mail Centre's 3221 postcode covers twenty rural locations in and around Geelong. Mail sent to these addresses is not fully sorted until it reaches Geelong. Others, even in cities, serve much smaller populations (e.g., postcode 4350 serves approximately 100,000 people in Toowoomba and surrounding areas). The Australian National University's postcode is 0200 (formerly 2601), while Cannonvale, Queensland's is 9944.

Locales with two postcodes for street delivery and post office boxes are rare. Large Volume Receiver (LVR) postcodes were assigned to large businesses, government departments, and other institutions that received a large volume of mail. In the 1990s, LVRs got more postcode ranges. Aussie Post has been phased out the LVR program since 2006.

Postcodes are now used by many more organizations. Postcodes are frequently used by insurers to calculate car and home insurance rates. Transport NSW assigns bus stop numbers based on postcodes in Greater Sydney. The stop number is between five and seven digits long, with the first four representing the postcode and the rest the bus stop (sometimes written with a space in between, e.g. "2000 108").

Many companies that produce metropolitan street maps include postcodes for suburbs in their indexes and maps. Postcodes are frequently used to delineate sales and franchise areas.

Statisticians from the Australian Bureau of Statistics, Taxation Office, and other federal and state government agencies use the Australia Post four-digit code for business and social planning. The problem with spatial representation of postcodes is that they tend to change over time as new postcodes are added or existing ones are split for operational reasons.

Australia Country Description

Australia is the world's smallest continent, in which it lies between the Pacific and Indian oceans. Canberra, Australia's capital, is situated between Sydney and Melbourne in the southeast.

From Cape York Peninsula to Wilsons Promontory, the Australian mainland stretches nearly 4,000 km west-east (3,200 km). Southernmost tip of Tasmania is within Australian jurisdiction, while northernmost tip of Papua New Guinea is within Australian jurisdiction. The Timor and Arafura seas separate Australia from Indonesia in the northwest, Papua New Guinea in the northeast, the Coral Sea Islands Territory in the southeast, and Antarctica in the far south.

Australia is the only country that governs a continent and its islands. The continent is the world's largest island and smallest continent. It lies between 10° and 39° South. Mount Kosciuszko, the mainland's highest point, is 2,228 metres.

Australia is the world's driest continent. Its interior has some of the world's lowest rainfall, with roughly three-quarters of the land arid or semi-arid. But its fertile areas are well-watered and help feed the world. Dry land sheep and cattle grazing requires soil care. Due to Australia's long rainfall cycles, some grazing land became desert.

Geographical Description of Australia

Except for Antarctica, Australia is the flattest and driest continent. From the air, its vast plains, sometimes red like dried blood, more often tawny like a lion's skin, appear to be one giant desert. From Darwin in the north or Perth in the west, one can fly to Sydney without seeing a town or anything other than the most sparse and minute signs of human habitation. Much of the central depression and western plateau is desert. But looks can be deceiving. Australian arid and foreboding regions conceal significant mineral wealth, and Queensland and New South Wales' red and black soil plains support the world's largest wool industry.

The coastal rim also escapes the prevailing flatness and aridity. The east coast, where European settlement began and where most Australians now live, is both topographically and hydrologically diverse.

This mountain range runs from Cape York in northern Queensland to Tasmania's southern seaboard. From the coast, that range appears as a bold range of mountains, despite the fact that few of its peaks exceed 5,000 feet (1,500 metres). A massive plateau with gently rolling hills, it resembles an escarpment leading down to the western plains. Except on the south coast, where the Nullarbor Plain stretches to the sea, where precipitation rapidly diminishes as one moves further inland.

Economy of Australia

Australia has a developed modern market economy and has recently had one of the world's most remarkable economies, with high growth, low inflation, and low interest rates. Over the last decade, inflation has typically been between 2 and 3 percent, while the base interest rate has been between 5 and 6 percent. There is an efficient public sector, a flexible labor market, and a vibrant business sector.

Since 1992, Australia has averaged greater than 3% economic growth over a 17-year period. Australia's economic stability places it among the developed world's leaders in terms of sustained growth rates.

The Australian economy is dominated by the service sector, which accounts for 68 percent of GDP. Agricultural and mining exports account for 57% of total exports.

Australia has enjoyed a high standard of living since the nineteenth century due to its abundant physical resources. Australia is a significant exporter of agricultural products, particularly wheat and wool, minerals such as iron ore and gold, and energy products such as liquefied natural gas and coal. It has invested significantly in social infrastructure, including education, training, health, and transportation.

Australian per capita GDP growth, according to the Reserve Bank of Australia, is faster than that of New Zealand, the United States, Canada, and the Netherlands. Australia's economic performance in the past has been heavily influenced by US, Japanese, and Chinese economic growth.
