Lieutenant James Cook (not yet a captain) chose Botany Bay as the most promising site for a new settlement. it is interesting to note that, when the First Fleet arrived eighteen years later, Captain Arthur Phillip did not find Botany Bay to be at all as Cook had described. He was forced to reconnoitre north in order to find a more suitable prospect.
