Australia, officially known as the Commonwealth of Australia, is a country in the Southern Hemisphere comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands in the Indian and Pacific Oceans.

Known as "the Land Down Under", Australia is famed globally for their "laid-back but unwittingly practical" characters and their history revolving around roguish personalities.

Australia's involvement in the world of superheroes and supervillains usually involves primal magic, the astral dimension known as the Dreamtime, and the country's indigenous race known as the Aboriginals.

For at least 40,000 years before European settlement in the late 18th century, Australia was inhabited by indigenous Australians (referred to as "Aboriginals"). After discovery by Dutch explorers in 1606, Australia's eastern half was claimed by Britain in 1770 and initially settled through convict penal transportation to the colony of New South Wales, formally founded on 7th February, 1788. The population grew steadily in subsequent decades; the continent was explored and an additional five self-governing Crown Colonies were established.

On 1 January 1901, the six colonies became a federation and the Commonwealth of Australia was formed. Since Federation, Australia has maintained a stable liberal democratic political system and is a Commonwealth realm. The nation's capital city is Canberra, in the Australian Capital Territory.

In 1942, during World War II, Brisbane was the site of a violent clash between visiting United States military personnel and Australian servicemen and civilians which resulted in one death and several injuries. This incident became known colloquially as the Battle of Brisbane.

During the great Invasion! Melbourne was used as a beachhead for the Alien Alliance because the Khunds believed that they would meet with the least superhuman resistance there. Eventually, they were repelled by Justice League International.

During the following year of the Infinite Crisis, the heroes trapped in a Zeta Beam were finally freed over the Australian desert. Further on through the year, Black Adam devastated Sydney due to the city's affiliation with Ridge Ferrick; a front company for Intergang.
One year later, Doctor Sivana used Sydney as a test trial for his new machine; the "Luddite", which sends something similar to a magnetic pulse that shuts down any piece of technology, from a cell phone to a car engine or a microwave oven, and renders it beyond repair. The pulse also wipes the human brain of advanced knowledge such as memory, reading or mechanical manipulation.
