Eendrachtsland

or are obsolete geographical names for an area centred on the Gascoyne region of Western Australia. Between 1616 and 1644, during the European Age of Exploration, was also a name for the entire Australian mainland. From 1644, it and the surrounding areas were known as New Holland.
In 1616, Dirk Hartog, captain of the Dutch East India Company ship, encountered the west coast of the Australian mainland, meeting it close to the 26th parallel south latitude, near what is now known as Dirk Hartog Island in Western Australia. After leaving the island, sailed in a northeastern direction along the coast of the mainland, Hartog charting as he went. He gave this land the name het Landt van d'Eendracht, in short, after his ship .

Appearance on the charts

The earliest known appearance of that name on the charts was eleven years later in 1627 on by Hessel Gerritsz. However, the name was in use as early as 1619.
was first revealed to the world in 1626 as on the small world map shown on the title page of the . This was the first published map to show any authentic part of the Australian coastline, denoting as part of a notionally much larger landmass.
also appeared on the world map by Jodocus Hondius II published in Amsterdam in 1625, and on the world map by Johannes Kepler and Philipp Eckebrecht, composed in 1630 and published in 1658 in Kepler's Rudolphine Tables.

Coastline knowledge

shows that the knowledge held by the Dutch of the Western Australian coastline was increasing, as the chart was based on a number of voyages, beginning with this 1616 voyage of Dirk Hartog.
The 1627 chart, broken here and there by unexplored openings, extends from the Willems River almost to Albany, Western Australia, spanning the Western Australian coastline for a distance of around. Heeres wrote in 1899 about the increase of Dutch knowledge of the Western Australian coastline:

Breaks in the coast

By the mid to late 1620s the Dutch had gathered a good deal of information, enabling them to chart with some accuracy the west coast of what had become known by then as. Heeres then goes on to say that the coastline showed breaks in various places, due to unexplored openings such as Exmouth Gulf. These gaps are clearly visible on the full-sized 1627 chart image:

True nature

Heeres then suggests that the mid seventeenth century navigators were constantly faced by the problem of the true character of this South-land, asking themselves the question:

End of the name

By 1644 most of these problems of gaps in the coastline were solved, spelling the end of the name, in favour of a name that, for the Dutch, was much closer to the heart:
