The south part of King Island had been found by the skipper of a sealing brig, named Reid, in 1799, but the name it bears was given to it by John Black, commander of the brig Harbinger, who discovered the northern part in January, 1801. Flinders was occupied for three days at King Island. On the 24th, the wind having moderated, he made for Cape Otway. But it was still considered imprudent to follow the shore too closely against a south-east wind; and on the 26th the ship ran across the water to Grant's Cape Schanck.

The details of these movements are of some moment, for the ship was nearing the gates of Port Philip. "We bore away westward," Flinders records, "in order to trace the land round the head of the deep bight." In view of the importance of the harbour which he was about to enter, we may quote his own description of his approach to it, and his surprise at what he found:

"On the west side of the rocky point,* (* Point Nepean.) there was a small opening, with breaking water across it. However, on advancing a little more westward the opening assumed a more interesting aspect, and I bore away to have a nearer view. A large extent of water presently became visible withinside, and although the entrance seemed to be very narrow, and there were in it strong ripplings like breakers, I was induced to steer in at half-past one; the ship being close upon a wind and every man ready for tacking at a moment's warning. The soundings were irregular, between 6 and 12 fathoms, until we got four miles within the entrance, when they shoaled quick to 2 3/4. We then tacked; and having a strong tide in our favour, worked to the eastward, between the shoal and the rocky point, with 12 fathoms for the deepest water. In making the last stretch from the shoal, the depth diminished from 10 fathoms quickly to 3; and before the ship could come round, the flood tide set her upon a mud bank and she stuck fast. A boat was lowered down to sound; and, finding the deep water lie to the north-west, a kedge anchor was carried out; and, having got the ship's head in that direction, the sails were filled, and she drew off into 6 and 10 fathoms; and it being then dark, we came to an anchor.

"The extensive harbour we had thus unexpectedly found I supposed must be Westernport; although the narrowness of the entrance did by no means correspond with the width given to it by Mr. Bass. It was the information of Captain Baudin, who had coasted along from thence with fine weather, and had found no inlet of any kind, which induced this supposition; and the very great extent of the place, agreeing with that of Westernport, was in confirmation of it. This, however, was not Westernport, as we found next morning; and I congratulated myself on having made a new and useful discovery. But here again I was in error. This place, as I afterwards learned at Port Jackson, had been discovered ten weeks before by Lieutenant John Murray, who had succeeded Captain Grant in the command of the Lady Nelson. He had given it the name of Port Phillip, and to the rocky point on the east side of the entrance that of Point Nepean."

It was characteristic of Flinders that he allowed no expression of disappointment to escape him, on finding that he had been anticipated by a few weeks in the discovery of Port Phillip. Baudin, it will be remembered, observed the satisfaction felt by his visitor in Encounter Bay, when he learnt that Le Geographe had not found King Island, because he thought he would have the happiness of being the first to lay it down upon a chart. In this he had been forestalled by Black of the Harbinger; and now again he was to find that a predecessor had entered the finest harbour in southern Australia. Disappointment he must have felt; but he was by no means the man to begrudge the success that had accrued to another navigator. He made no remark, such as surely might have been forgiven to him, about the determining accidents of time and weather; though it is but right for us to observe that, had the Investigator been permitted to sail from England when she was ready (in April, 1801) instead of being delayed by the Admiralty officials till July, Port Phillip, as well as the stretch of coast discovered by Baudin, would have been found by Flinders. That delay was caused by nothing more than a temporary illness of the Secretary of the Admiralty, Evan Nepean, whose name is commemorated in Point Nepean, one of the headlands flanking the entrance to the Port.

A perfectly just recognition of the real significance of Flinders in southern exploration has led to his name being honoured and commemorated even with respect to parts where he was not the actual discoverer. It is a function of history to do justice in the large, abiding sense, discriminating the spiritual potency of personalities that dominate events from the accidental connection of lesser persons with them. In that wider sense, Flinders was the true discoverer of the whole of the southern coast of Australia. He, of course, made no such claim; but we who estimate the facts after a long lapse of years can see clearly that it was so. Only the patching up of the old Reliance kept him in Sydney while Bass was creeping round the coast to Westernport. Only the illness of an official and other trifling causes prevented him from discovering Port Phillip. It was the completion of his chart of Bass Strait, based upon his friend's memoranda, that led the Admiralty to direct Grant to sail through the strait from the west, and so enabled him to be the first to come upon the coast from Cape Banks to Cape Schanck. It was only the delay before-mentioned and the contrary winds that hindered him from preceding Baudin along the fifty leagues that are credited to that navigator.

Thus it is that although not a league of the coastline of Victoria is in strict verity to be attributed to Flinders as discoverer, he is habitually cited as if he were. Places are named after him, memorials are erected to him. The highest mountain in the vicinity of Port Phillip carries on its summit a tablet celebrating the fact that Flinders entered the port at the end of April, 1802; but there is nowhere a memorial to remind anyone that Murray actually discovered it in January of the same year. The reason is that, while it is felt that time and circumstance enabled others to do things which must be inscribed on the historical page, the triumph that should have followed from skill, knowledge, character, preparation and opportunities well and wisely used, was fairly earned by Flinders. The dates, not the merits, prevent their being claimed for him. His personality dominates the whole group of discoveries. We chronicle the facts in regard to Grant, Baudin, Murray, and Bass, but we feel all the time that Flinders was the central man.

Not being aware of Murray's good fortune in January, Flinders treated Port Phillip as a fresh discovery, and examined its approaches with as much thoroughness as his resources would allow. At this time, however, the store of provisions was running low. The Investigator was forty weeks out from England, and re-equipment was fast becoming imperative. Her commander had felt the urgency of his needs before he reached Port Phillip. He had seriously considered whether he should not make for Sydney from King Island. "I determined, however, to run over to the high land we had seen on the north side of Bass Strait, and to trace as much of the coast from thence eastward as the state of the weather and our remaining provisions could possibly allow."

As related in the passage quoted above, Flinders at first thought he had reached Westernport, though the narrowness of the entrance did not correspond with Bass's description of the harbour he had discovered four years previously. But Baudin had told him that he found no port or harbour of any kind between Westernport and Encounter Bay. Consequently, it was all the more astonishing to behold this great sheet of blue water broadening out to shores overlooked by high hills, and extending northward further than the eye could penetrate. It was not until the following day, April 27th, that he found he was not in the port which his friend had discovered in the whaleboat. Immediately after breakfast he rowed away from the ship in a boat, accompanied by Brown and Westall, to ascend the bluff mountain on the east side which Murray had named Arthur's Seat. From the top he was able to survey the landscape at a height of a thousand feet; and then he saw the waters and islands of Westernport lying beneath him only a few miles further to the east, whilst, to his surprise, the curves of Port Phillip were seen to be so extensive "that even at this elevation its boundary to the northward could not be distinguished."
