This discusses the geo-political status of the Australiasian region including the Dutch East Indies, New Holland and New Zealand prior to Cook's first voyage from a European "Doctrines of Discovery" perspective. The Dutch had a fairly solid claim of "first discovery" over New Holland. This discusses the basis of Dutch claims, and touches on a possible catalyst that got the ball rolling for the British to move-in, and how the origins of the Australian doctrine of terra nullius may trace back to Abel Tasman.
