The Portuguese, Spanish and the English were the dominant navigational powers. During the 17th century the Dutch overthrew everyone else, and became the mightiest seafarers. They flourished in the spice trade. They even started a trading company called Vereenigde Oostindische Compagnie, abbreviated to VOC.
They realized that the route around the Cape of Good Hope was more suitable to reach the Far East. They had a base on the island of Jakarta, which they called Batavia. By the 1620s the Dutch were well established in Indonesia.
Later, there had been sightings of a land to the south. Many Dutch seafarers tried to locate the land. Willem Jansz, a Dutchman became the first European to discover Australia, but he remained unaware of his achievement.
Later, Dirk Hartog made landfall on an island off the coast of Shark Bay, Western Australia. The island was later named the Dirk Hartog Island after him. But the Dutch made no claim to the land, and they made no attempt to colonize it unlike the other European explorers.
