Eendrachtsland or Eendraghtsland was derived from T Landt van d'Eendracht or Land van de Eendracht and was one of the earliest names given for Australia, being in use for 28 years, from 1616 until 1644.
In 1616 Dirk Hartog sailed from the west in the Dutch East India Company ship Eendracht and encountered the west coast of the Australian mainland, meeting it close to the 26th parallel south latitude (26° south) near what is now known as Dirk Hartog Island in Western Australia.
After leaving the island, the Eendracht sailed in a north-west direction along the West Australian coastline, Hartog charting as he went. He gave this land the name T'Landt van d'Eendracht or "Eendrachtsland", after his ship, the Eendracht, meaning "Unity".
