Watkin Tench (1759?-1853) sailed with Governor Phillip in the First Fleet to Australia, 1787-8, and remained for four years from 20 January 1788 to 18 December 1791. He was involved in the establishment of a permanent settlement at Port Jackson and served as a Captain-Lieutenant. This is considered one of the six ‘First Fleet’ accounts to be published an done of the scarcest despite there being over 500 subscribers. Tench explored the region around the nascent colony and discovered the Nepean River. This is Tench’s second work, the first being published in 1789. This work is greatly expanded and completes the account of the first years in the colony. ‘The map and text give important and full details of the early expeditions of discovery to the south and to the wet, including those which Tench led himself. As an accurate, well-written and acutely observed account of the earliest years of Australia’s colonization it is a most important addition to any collection of Australian books’ (Wantrup). The map is entitled ‘A Map of the hitherto unexplored country contiguous to Port Jackson: laid down from actual survey’. ESTC T136607; Ferguson 171; Wantrup pp. 71-2, no. 16.
