"It’s a little known fact that Muslim visitors first arrived in Australia well before the British established a colony in 1788. From at least as early as 1650, Muslim fishermen from Makassar in Indonesia made annual trips to Australia's far north coast in search of sea cucumbers—or trepang—which are highly valued in Chinese medicine and cooking. Indigenous Australians also journeyed to Indonesia, trading tortoise shells, tools, tobacco and other goods."
