Politics
Parliament House, Canberra was opened in 1988, replacing the provisional Parliament House building opened in 1927.
The Commonwealth of Australia is a constitutional democracy based on a federal division of powers. The form of government used in Australia is a constitutional monarchy with a parliamentary system of government. Queen Elizabeth II is the Queen of Australia, a role that is distinct from her position as monarch of the other Commonwealth realms. The Queen is represented by the Governor-General at federal level and by the Governors at state level. Although the Constitution gives extensive executive powers to the Governor-General, these are normally exercised only on the advice of the Prime Minister. The most notable exercise of the Governor-General's reserve powers outside the Prime Minister's direction was the dismissal of the Whitlam Government in the constitutional crisis of 1975.[38]
There are three branches of government:
· The legislature: the Commonwealth Parliament, comprising the Queen, the Senate, and the House of Representatives; the Queen is represented by the Governor-General, who by convention acts on the advice of his or her Ministers.[39]
· The executive: the Federal Executive Council (the Governor-General as advised by the Executive Councillors); in practice, the councillors are the Prime Minister and Ministers of State.[citation needed]
· The judiciary: the High Court of Australia and other federal courts. Appeals from Australian courts to the Judicial Committee of the Privy Council in the United Kingdom ceased when the Australia Act of 1986 was passed.[40]
The bicameral Commonwealth Parliament consists of the Queen, the Senate (the upper house) of 76 senators, and a House of Representatives (the lower house) of 150 members. Members of the lower house are elected from single-member constituencies, commonly known as "electorates" or "seats", allocated to states on the basis of population, with each original state guaranteed a minimum of five seats. In the Senate, each state is represented by twelve senators, and each of the territories (the Australian Capital Territory and the Northern Territory) by two. Elections for both chambers are normally held every three years, simultaneously; senators have overlapping six-year terms, since only half of places in the Senate are put to each election unless the cycle is interrupted by a double dissolution. Although the Prime Minister is appointed by the Governor-General, in practice the party with majority support in the House of Representatives forms government and its leader becomes Prime Minister.[41]
There are two major political groups that form government, federally and in the states: the Australian Labor Party, and the Coalition which is a formal grouping of two parties: the Liberal Party and its minor partner, the National Party. Independent members and several minor parties—including the Greens and the Australian Democrats—have achieved representation in Australian parliaments, mostly in upper houses. The Labor Party came to office with Kevin Rudd as Prime Minister following the November 2007 election. Every Australian parliament (federal, state, and territory) then had a Labor government until September 2008 when the Liberal Party formed a minority government in association with the National Party in Western Australia. In the 2004 election, the previous governing coalition led by John Howard won control of the Senate—the first time in more than 20 years that a party (or a coalition) has done so while in government. Voting is compulsory for all enrolled citizens 18 years and over, in each state and territory and at the federal level.[42] Enrolment to vote is compulsory in all jurisdictions except South Australia.[43]
States and territories
Australia has six states—New South Wales, Queensland, South Australia, Tasmania, Victoria, and Western Australia—and two major mainland territories—the Northern Territory and the Australian Capital Territory (ACT). In most respects these two territories function as states, but the Commonwealth Parliament can override any legislation of their parliaments. By contrast, federal legislation only overrides state legislation in certain areas that are set out in Section 51 of the Australian Constitution; state parliaments retain all residual legislative powers, including powers over education, police, the judiciary, roads, public transport, and local government as these do not fall under the provisions listed in Section 51.[44]
Each state and major mainland territory has its own legislature or parliament: unicameral in the Northern Territory, the ACT, and Queensland, and bicameral in the remaining states. The states are sovereign, though subject to certain powers of the Commonwealth as defined by the Constitution. The lower house is known as the Legislative Assembly (House of Assembly in South Australia and Tasmania) and the upper house is known as the Legislative Council. The head of the government in each state is the Premier, and in each territory the Chief Minister. The Queen is represented in each state by a Governor; an Administrator in the Northern Territory, and the Australian Governor-General in the ACT, have analogous roles.[citation needed]
The federal government directly administers the following territories:
· Jervis Bay Territory, a naval base and sea port for the national capital in land that was formerly part of New South Wales
· Christmas Island and Cocos (Keeling) Islands
· Ashmore and Cartier Islands
· Coral Sea Islands
· Heard Island and McDonald Islands
· Australian Antarctic Territory
Norfolk Island is also technically an external territory; however, under the Norfolk Island Act 1979 it has been granted more autonomy and is governed locally by its own legislative assembly. The Queen is represented by an Administrator, currently Owen Walsh.[45]
Foreign relations and military
The Australian War Memorial
Over recent decades, Australia's foreign relations have been driven by a close association with the United States through the ANZUS pact, and by a desire to develop relationships with Asia and the Pacific, particularly through ASEAN and the Pacific Islands Forum. In 2005 Australia secured an inaugural seat at the East Asia Summit following its accession to the Treaty of Amity and Cooperation in Southeast Asia. Australia is a member of the Commonwealth of Nations, in which the Commonwealth Heads of Government meetings provide the main forum for cooperation. Australia has energetically pursued the cause of international trade liberalisation. It led the formation of the Cairns Group and Asia-Pacific Economic Cooperation. Australia is a member of the Organisation for Economic Co-operation and Development and the World Trade Organization, and has pursued several major bilateral free trade agreements, most recently the Australia – United States Free Trade Agreement and Closer Economic Relations with New Zealand. Australia is also negotiating a free trade agreement with Japan, with whom Australia has close economic ties as a trusted partner in the Asia-Pacific region.[46] Australia, along with New Zealand, the United Kingdom, Malaysia, and Singapore are party to the Five Power Defence Arrangements, a regional defence agreement. A founding member country of the United Nations, Australia is strongly committed to multilateralism along with its middle power allies Canada and the Nordic countries, and maintains an international aid program under which some 60 countries receive assistance. The 2005–06 budget provides A$2.5billion for development assistance;[47] as a percentage of GDP, this contribution is less than that recommended in the UN Millennium Development Goals. Australia ranks 7th overall in the Center for Global Development's 2008 Commitment to Development Index.[48]
Australia's armed forces—the Australian Defence Force (ADF)—comprise the Royal Australian Navy (RAN), the Australian Army, and the Royal Australian Air Force (RAAF), in total numbering 73,000 personnel (including 53,000 regulars and 20,000 reservists).[49] Australia's military is 68th largest in the world, but one of the world's smallest in per capita terms. All branches of the ADF have been involved in UN and regional peacekeeping (most recently in East Timor, the Solomon Islands, and Sudan), disaster relief, and armed conflict, including the 2003 invasion of Iraq. The government appoints the Chief of the Defence Force from one of the armed services; the current Chief of the Defence Force is Air Chief Marshal Angus Houston. In the 2006–07 budget, defence spending was A$22billion,[50] accounting for less than 1% of global military spending. Australia was placed 27th on the 2008 Global Peace Index, primarily due to its presence in Afghanistan.[51] While the Governor-General is the Commander-in-Chief of the Australian Defence Force, he or she does not play an active part in the ADF's command structure as the elected Australian Government controls the ADF.[52]
Geography
Climatic zones in Australia, based on the Köppen climate classification
Australia's landmass of 7,617,930square kilometres (2,941,300sqmi)[53] is on the Indo-Australian Plate. Surrounded by the IndianN4 and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas. The world's smallest continent[9] and sixth largest country by total area,[8] Australia – owing to its size and isolation – is often dubbed the 'island continent'[54] and variably considered the world's largest island.[55] Australia has 34,218kilometres (21,262mi) of coastline (excluding all offshore islands)[56] and claims an extensive Exclusive Economic Zone of 8,148,250square kilometres (3,146,060sqmi). This exclusive economic zone does not include the Australian Antarctic Territory.
The Great Barrier Reef, the world's largest coral reef,[57] lies a short distance off the north-east coast and extends for over 2,000kilometres (1,240mi). Mount Augustus, claimed to be the world's largest monolith,[58] is located in Western Australia. At 2,228metres (7,310ft), Mount Kosciuszko on the Great Dividing Range is the highest mountain on the Australian mainland, although Mawson Peak on the remote Australian territory of Heard Island is taller at 2,745metres (9,006ft).
By far the largest part of Australia is desert or semi-arid lands commonly known as the outback. Australia is the flattest continent, with the oldest and least fertile soils, and is the driest inhabited continent. Only the south-east and south-west corners of the continent have a temperate climate. The population density, 2.8 inhabitants per square kilometre, is among the lowest in the world, although a great proportion of the population lives along the temperate south-eastern coastline.
The landscapes of the northern part of the country, with a tropical climate, consist of rainforest, woodland, grassland, mangrove swamps, and desert. The climate is significantly influenced by ocean currents, including the Indian Ocean Dipole and the El Niño-Southern Oscillation, which is correlated with periodic drought, and the seasonal tropical low pressure system that produces cyclones in northern Australia.[59]
Environment
Although most of Australia is semi-arid or desert, it includes a diverse range of habitats from alpine heaths to tropical rainforests, and is recognised as a megadiverse country. Because of the continent's great age, its extremely variable weather patterns, and its long-term geographic isolation, much of Australia's biota is unique and diverse. About 85% of flowering plants, 84% of mammals, more than 45% of birds, and 89% of in-shore, temperate-zone fish are endemic.[60] Australia has the greatest number of reptiles of any country, with 755 species.[61]
Many of Australia's ecoregions, and the species within those regions, are threatened by human activities and introduced plant and animal species. The federal Environment Protection and Biodiversity Conservation Act 1999 is a legal framework for the protection of threatened species. Numerous protected areas have been created under the national Biodiversity Action Plan to protect and preserve unique ecosystems; 64 wetlands are registered under the Ramsar Convention, and 15 natural World Heritage Sites have been established.[62] Australia was ranked 46th of 149 countries in the world on the 2008 Environmental Performance Index.[63] Australian forests often contain a wide variety of eucalyptus trees and are mostly located in higher rainfall regions.
Most Australian woody plant species are evergreen and many are adapted to fire and drought, including many eucalypts and acacias. Australia has a rich variety of endemic legume species that thrive in nutrient-poor soils because of their symbiosis with rhizobia bacteria and mycorrhizal fungi. Among well-known Australian fauna are the monotremes (the platypus and the echidna); a host of marsupials, including the kangaroo, the koala, and the wombat; the saltwater and freshwater crocodiles; and birds such as the emu and the kookaburra. Australia is home to many dangerous animals including some of the most venomous snakes in the world.[64] The dingo was introduced by Austronesian people who traded with Indigenous Australians around 3000 BCE.[65] Many plant and animal species became extinct soon after first human settlement,[66] including the Australian megafauna; others have become extinct since European settlement, among them the thylacine.[67]
Climate change has become an increasing concern in Australia in recent years,[68] with many Australians considering protection of the environment to be the most important issue facing the country.[69] The first Rudd Ministry has initiated several emission reduction activities;[70] Rudd's first official act, on his first day in office, was to sign the instrument of ratification of the Kyoto Protocol. Nevertheless Australia's carbon dioxide emissions per capita are one of the highest in the world, lower than only a few other industrialised nations including the United States and Canada. Rainfall in Australia has slightly increased over the past century, both nationwide and for two quadrants of the nation,[71] while annual mean temperatures increased significantly over the past decades.[72] Water restrictions are currently in place in many regions and cities of Australia in response to chronic shortages due to urban population increases and localised drought.[73]
