What do we know about Australia before the British came?

Before the British came to Australia the aboriginals where the only people living in Australia. The British weren’t the first ones to discover Australia. Australia had been visited for centuries by Dutch, French, Macassan, Arab, and Portuguese explorers and traders. Most European sailors where actually sailing to java to get spices. Dirt Cartog was a Dutch man who came past the Australia while going to java. Chinese traders came centuries before the Europeans and the British explorers.

The Macassans were also explorers that explored the world. The Macassans sailed to Australia in boats called praus and fished for trepang in dugout canoes. Some of these canoes were traded with the Indigenous people, who learned from the design and started making their own canoes. Macassan people traded other objects with the Indigenous people. Knives, axes, smoking pipes and fish-hooks were traded in exchange for tortoise shells and pearl shells. The Macassans also influenced the art, stories, dance, language, and rituals of the Indigenous people in the region.
