New Holland is a
historical European name for
mainland Australia. The name was first applied to Australia in 1644 by the
Dutch seafarer
Abel Tasman. The name came to be applied to whole "Southern land" or
Terra Australis, though the coastline of the continent had still not been fully explored; but after the British settlement in
Sydney in 1788 the territory to the east of the continent claimed by Britain was named
New South Wales, leaving the western part as New Holland. New Holland continued to be used semi-officially and in popular usage as the name for the whole continent until at least the mid-1850s.
