Prime Minister Howard sent 2,000 Australian troops to fight alongside American and British troops in the 2003 Iraq war, despite strong opposition among Australians.

In July 2003, Australia successfully restored order to the Solomon Islands, which had descended into lawlessness during a brutal civil war.

Australia fought alongside Britain in World War I, notably with the Australia and New Zealand Army Corps (ANZAC) in the Dardanelles campaign (1915). Participation in World War II helped Australia forge closer ties to the United States.

Parliamentary power in the second half of the 20th century shifted between three political parties: the Australian Labour Party, the Liberal Party, and the National Party. Australia relaxed its discriminatory immigration laws in the 1960s and 1970s, which favored Northern Europeans.

Geography

The continent of Australia, with the island state of Tasmania, is approximately equal in area to the United States (excluding Alaska and Hawaii). Mountain ranges run from north to south along the east coast, reaching their highest point in Mount Kosciusko (7,308 ft; 2,228 m).

The western half of the continent is occupied by a desert plateau that rises into barren, rolling hills near the west coast. The Great Barrier Reef, extending about 1,245 mi (2,000 km), lies along the northeast coast. The island of Tasmania (26,178 sq mi; 67,800 sq km) is off the southeast coast.
