In 1697 Willem De Vlamingh charted the Perth region with the
vessels Geelvinck, Nijptang and Weseltje. He
travelled 80 kms inland on the Swan River with ship's artist
Victorszoon, making pictorials of the coast.
Landing on Dirk Hartog Island, off the West Australian coast, De
Vlamingh replaced a pewter plate left by Hartog in 1616 and then
charted Christmas Island. An account is given in Early Voyages to Terra Australis by
R H Major.
