The south-east- and east-coasts of Australia have never been visited by the ships of the East India Company. Tasman and Visscher [*] discovered Tasmania (Van Diemen's land) in 1642, but were unaware of the existence of what is now known as Bass Strait; they discovered the west-coast of New Zealand (Staten-land) and certain island-groups east of Australia, but did not touch at or sight the east-coast of Australia. Of course, after the discovery of the west-coast of New Zealand and of the island-groups east of Australia [**], the existence of an east-coast of Australia to westward of the regions thus discovered, was an indubitable fact, but this east-coast itself was never visited by the Netherlanders.
[* See the journal of this voyage and the discussion of it in my Tasman Folio.]
[** In the year 1616 Lemaire and Schouten (No. V), and in 1722 Roggeveen (No. XXXIV), also touched at various island-groups east of Australia, but these voyages fall outside the plan of the present work.]

OBJECT OF THE DUTCH VOYAGES FOR THE DISCOVERY OF THE SOUTH-LAND.--CONCLUSION.
Although it is quite true that the south-east- and east-coasts of the Australian continent were not discovered by Dutch ships, still it is an undoubted fact that, so far as is known up to now, the whole of the Australian coast-line from Prince of Wales Island and York Peninsula and along the Gulf of Carpentaria, the north- and north-west-coast of Australia then following, the whole of the west-coast, and the south-coast down to the islands of St. François and St. Pieter (133° 30' E. L. Greenwich) were in the 17th century discovered by vessels belonging to the Netherlands [*].
[* It is true that Dampier touched at the north-west coast in 1688, but at that time this coast had already been surveyed by Dutch skippers.]
We now come to the question of the object which the Dutch authorities had in view in arranging for the expeditions that ultimately led to these discoveries.
In answering this question we shall have to distinguish between two different categories of voyages: among the voyages undertaken by Netherlanders that have led to discoveries on the coasts of Australia, there are some which were not begun with the express purpose of going in search of unknown lands; but there are others also that were undertaken expressly with this end in view. Of course the second class only can be called exploratory expeditions in a more restricted sense--the voyages of the first category became voyages of discovery through accidental circumstances.
