European exploration of Australia

The European exploration of Australia first began in February 1606, when Dutch navigator Willem Janszoon landed in Cape York Peninsula and on October that year when Spanish explorer Luís Vaz de Torres sailed through, and navigated, Torres Strait islands. Twenty-nine other Dutch navigators explored the western and southern coasts in the 17th century, and dubbed the continent New Holland. Most of the explorers of this period concluded that the apparent lack of water and fertile soil made the region unsuitable for colonisation.

Other European explorers followed until, in 1770, Lieutenant James Cook charted the east coast of Australia for Great Britain. Later, after Cook's death, Joseph Banks recommended sending convicts to Botany Bay (now in Sydney), New South Wales. A First Fleet of British ships arrived at Botany Bay in January 1788 to establish a penal colony, the first colony on the Australian mainland. In the century that followed, the British established other colonies on the continent, and European explorers ventured into its interior.

Massive areas of land were cleared for agriculture and various other purposes in the first 100 years of European settlement. In addition to the obvious impacts this early clearing of land and importation of hard-hoofed animals had on the ecology of particular regions, it severely affected indigenous Australians, by reducing the resources they relied on for food, shelter and other essentials. This progressively forced them into smaller areas and reduced their numbers as the majority died of newly introduced diseases and lack of resources. Indigenous resistance against the settlers was widespread, and prolonged fighting between 1788 and the 1920s led to the deaths of at least 20,000 indigenous people and between 2,000 and 2,500 Europeans.
