A history of this establishment at the extremity of the globe, in a country where the astonished settler sees nothing, not even the grass under his feet, which is not different to whatever had before met his eye, could not but present objects of great interest to the European reader; and the public curiosity has been gratified by the perusal of various respectable publications, wherein the proceedings of the colonists, the country round Port Jackson, its productions, and native inhabitants, are delineated with accuracy, and often with minuteness.  The subject to be here treated is the progress of maritime geographical discovery, which resulted from the new establishment; and as the different expeditions made for this purpose are in many cases imperfectly, and in some altogether unknown, it has been judged that a circumstantial account of them would be useful to seamen, and not without interest to the general reader.  These expeditions are, moreover, intimately connected with the Investigator’s voyage, of which they were, in fact, the leading cause.

(Atlas, Plate VIII.)

The first advantage to maritime geography which arose from the new settlement, was a survey of Botany and Broken Bays and Port Jackson, with most of the rivers falling into them.  Botany Bay had, indeed, been examined by captain Cook; but of the other two harbours, the entrances alone had been seen.  This survey, including the intermediate parts of the coast, was made by captain John Hunter, and was published soon after its transmission to England by governor Phillip.

In the beginning Of 1795, captain (now vice-admiral) Hunter sailed a second time for New South Wales, to succeed captain Phillip in the government of the new colony.  He took with him His Majesty’s armed vessels Reliance and Supply; and the author of this account, who was then a midshipman and had not long before returned from a voyage to the South Seas, was led by his passion for exploring new countries, to embrace the opportunity of going out upon a station which, of all others, presented the most ample field for his favourite pursuit.

On arriving at Port Jackson, in September of the same year, it appeared that the investigation of the coast had not been greatly extended beyond the three harbours; and even in these, some of the rivers were not altogether explored.  Jervis Bay, indicated but not named by captain Cook, had been entered by lieutenant Richard Bowen; and to the north, Port Stephens had lately been examined by Mr C. Grimes, land surveyor of the colony, and by captain W. R. Broughton of H. M. ship Providence; but the intermediate portions of coast, both to the north and south, were little further known than from captain Cook’s general chart; and none of the more distant openings, marked but not explored by that celebrated navigator, had been seen.

In Mr George Bass, surgeon of the Reliance, I had the happiness to find a man whose ardour for discovery was not to be repressed by any obstacles, nor deterred by danger; and with this friend a determination was formed of completing the examination of the east coast of New South Wales, by all such opportunities as the duty of the ship and procurable means could admit.
