A series of navigators, mostly operating from Sydney, explored the south-east coast of the Australian continent. In 1797 George Bass discovered Bass Strait, the passage between the Australian mainland and Van Diemen's Land (Tasmania); Bass sailed as far west as Western Port. Other navigators included James Grant in 1800. In 1802 John Murray in the "Lady Nelson" became the first recorded European to sail into Port Phillip, but he did not reach the northern end of the bay. He was followed shortly after by Matthew Flinders. In January 1803, Charles Robbins and Charles Grimes in the schooner "Cumberland" explored the whole of the bay, and found the mouth of the Yarra River, on which they rowed as far as Dights Falls at Collingwood.
