At the start of the 20th century when Australia was in need of a capital, leaders from the two major cities at the time, Sydney and Melbourne, both fought to make their city the center of the new nation. Canberra, which is located 160 miles southwest of Sydney and 400 miles away from Melbourne, was selected as a compromise.

Britain used Australia as a free-range prison starting in the 1780s, setting up penal colonies for political enemies and criminals alike. By the mid-1800s, more than 160,000 convicts were shipped from the British Isles to Australia. Today, one in five Aussies can trace their lineage to these criminal ancestors, according to the BBC.

There are around 25 million Aussies as of 2019, and roughly a third of them were born overseas, according to the Australian Bureau of Statistics. Compare that to the U.S., which is around the same size as Australia but has more than 300 million people, with just under 14% foreign-born.

Roughly 3 % of Aussies are of Aboriginal heritage, which means they are descended from people who lived on the continent before European colonization. When the Europeans arrived in the 16th century, Australia had at least 400 distinct groups of people who spoke hundreds of different languages, including the Nunga, Palawah, Murri and Gunggari.

The million or so people living in Australia before European colonization may beg to differ, but the history books officially list Captain James Cook of England as being the "discoverer" of Australia in 1770. While the Dutch got their earlier, sailing to Tasmania in the 1640s, they never bothered to colonize the land the way the Brits did a century earlier.

Victoria was a British colony in 1851 when a massive gold rush began in the area. The gold helped to make Melbourne into a major financial center but also triggered the Eureka Stockade, an 1854 rebellion by miners who didn't want to pay the British government for expensive mining licenses.

As salty as the Dead Sea, Lake Hillier in Western Australia is famous for its bubblegum-pink color, and it's not the only pink lake in the country. Best of all, this lake is actually safe to swim in if you can reach its remote location because the color comes from algae, not chemicals.

Dingos are wild dogs weighing 35 to 40 pounds that are found throughout Australia. The term became well-known around the globe in 1980 when a woman on a camping trip told police a dingo stole her baby.
