Matthew Flinders Journal – Port Phillip Bay – 26th April to 3rd May 1802

Matthew Flinders (born 16th March 1774 – died 19th July 1814) is one of the world’s most accomplished navigators and hydrographers.  He managed enormous feats from his totally unsuitable, leaking, rotting, unseaworthy vessels provided to him by the governance of the time.

Matthew Flinders charted Port Phillip Bay from late April to early May 1802.  His journal clearly describes the You Yangs, Arthurs Seat, views of Western Port from Arthurs Seat in the distance – his delight when he ate his first Oyster – the winds, the seas, the landscapes . . .

He notes only 3 landmarks during his visit to Port Phillip being “Arthurs Seat“, “Indented Point(now known as the “Bellarine Peninsula”) and “Hat Rock(which is the rocky outcrop forming the east perimeter of the natural harbour at Portarlington).

An unsung hero, Matthew Flinders accomplished the most amazing work – mapping Australia during the period 1795 to December 1803, when he was imprisoned by the French.  His maps represent an accuracy that is only improved with the assistance of the satellites and computers of the modern age.  Sir JK Laughton wrote in the Dictionary of National Biography:

” . . . Nobody can study Flinders’ beautiful charts without recognising them as the work of a master of his craft; and so well did he fulfil his promise, until the debility of his ship and a chain of misfortunes interposed to prevent him, that the Admiralty charts in current use are substantially those which Flinders made over a hundred years ago . . . “

Matthew Flinders R.N. & Crew on H.M. Survey Sloop ‘The Investigator’

The following extract is a transcript of Matthew Flinders’ journal during his time in Port Phillip, unbeknownst to him at the time, just 10 weeks after Lieutenant Murray’s visit:

The following excerpt of a transcription of Matthew Flinder’s Journal recording his voyage to Terra Australis in H.M. Sloop ‘Investigator’,  describes his discoveries of Port Phillip Bay, during the period 26th April 1802 to 3rd May 1802, noting that any explanations added to the original text by the transcriber, are denoted in [brackets]:


The extensive harbour we had thus unexpectedly found I supposed must be Western Port, 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 Western Port, was in confirmation of it.  This, however, was not Western Port, as we found next morning [TUESDAY 27 APRIL 1802]; 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.

Extract – Matthew Flinders Chart of Terra Australis – Sheet V – South Coast c 1814

Our situation was found in the morning to be near two miles from the south shore, and the extreme towards Point Nepean bore N. 83° W., two leagues.  About three miles to the north-by-west were some dry rocks, with bushes on them, surrounded with mud flats; and they appeared to form a part of the same shoal from which we had three times tacked in 2½ and 3 fathoms.  The mud bank where the ship had grounded is distinct from the middle shoal; but I am not certain that it is so from the south shore, from which it is one mile distant.  The Bluff Mount (named Arthur’s Seat by Mr. Murray, from a supposed resemblance to the hill of that name near Edinburgh) bore S. 76° E.; but from thence the shore trended northward so far that the land at the head of the port could not be seen even from aloft.  Before proceeding any higher with the ship I wished to gain some knowledge of the form and extent of this great piece of water; and Arthur’s Seat being more than a thousand feet high and near the water-side, presented a favourable station for that purpose.

After breakfast I went away in a boat, accompanied by Mr. Brown and some other gentlemen, for the Seat.  It was seven or eight miles from the ship; and in steering nearly a straight course for it we passed over the northern skirt of the shoal where the ship had touched; but afterwards had from 7 to 5 fathoms nearly to the shore.  Having observed the latitude there from an artificial horizon, I ascended the hill; and to my surprise found the port so extensive, that even at this elevation its boundary to the northward could not be distinguished.  The western shore extended from the entrance ten or eleven miles in a northern direction to the extremity of what, from its appearance, I called Indented Head; beyond it was a wide branch of the port leading to the westward, and I suspected might have a communication with the sea; for it was almost incredible that such a vast piece of water should not have a larger outlet than that through which we had come.

I took an extensive set of bearings from the clearest place to be found on the north-western, bluff part of the hill; and we afterwards walked a little way back upon the ridge.  From thence another considerable piece of water was seen, at the distance of three or four leagues; it seemed to be mostly shallow; but as it appeared to have a communication with the sea to the south, I had no doubt of its being Mr. Bass’s Western Port.

Arthur’s Seat and the hills and vallies in its neighbourhood were generally well covered with wood; and the soil was superior to any upon the borders of the salt water which I have had an opportunity of examining in Terra Australis.  There were many marks of natives, such as deserted fire-places and heaps of oyster shells; and upon the peninsula which forms the south side of the port a smoke was rising, but we did not see any of the people.  Quantities of fine oysters were lying upon the beaches, between high and low water marks, and appeared to have been washed up by the surf; a circumstance which I do not recollect to have observed in any other part of this country.


We returned on board at dusk in the evening; and at daylight the anchor was weighed with the intention of coasting round the port with the ship.  The wind was at north-east, but the flood tide was in our favour; and having made a stretch toward the middle shoals, we tacked and ran east-south-east along their south side, until past eight, when, the flood having ceased, we came to in 7 fathoms.  At slack water in the afternoon we again steered eastward, but were soon obliged to anchor for want of wind; and I found that this slow mode of proceeding was not at all suited to the little time for which we had provisions remaining, besides that there was much probability of getting frequently aground; the plan of examining the port with the ship was therefore abandoned.

Having left orders with Mr. Fowler, the first lieutenant, to take the ship back to the entrance, I went in a boat early next morning [THURSDAY 29 APRIL 1802] with provisions for three days, in order to explore as much of the port as could be done in that time.  Round the east end of the middle shoals I carried 6 and 7 fathoms; and keeping north-eastward, had 8 and 9 fathoms at a mile or more from the shore, and 4 close past the second rocky point above Arthur’s Seat.  The wind being at north-west, I was obliged to land behind some rocks more than two miles short of the third point, but walked to it with my surveying instruments.  This was nine miles from the Seat, and the furthest part of the shore seen from thence; further on the shore falls back more eastward, in long sandy beaches, and afterwards curves to the north-west; but it was lost to sight long before joining the land on the west side of the port.  After taking angles and observing for the latitude and longitude, I rowed to windward for Indented Head, five leagues off.  At the end of the first mile and a half the depth was 11 fathoms, but afterwards no bottom at 12 until within two miles of the western shore, where it was 9 fathoms.  We landed at nine o’clock at night, near the uppermost part which had yet been seen.


In the morning a fire was perceived two hundred yards from the tent; and the Indians appeared to have decamped from thence on our landing.  Whilst I was taking angles from a low point at the north-easternmost part of Indented Head, a party of the inhabitants showed themselves about a mile from us; and on landing there we found a hut with a fire in it, but the people had disappeared, and carried off their effects.  I left some strips of cloth, of their favourite red colour, hanging about the hut, and proceeded westward along the shore to examine the arm of the port running in that direction.

Three natives having made their appearance abreast of the boat, we again landed.  They came to us without hesitation, received a shag and some trifling presents with pleasure, and parted with such of their arms as we wished to possess without reluctance.  They afterwards followed us along the shore; and when I shot another bird, which hovered over the boat, and held it up to them, they ran down to the water-side and received it without expressing either surprise or distrust.  Their knowledge of the effect of fire-arms I then attributed to their having seen me shoot birds when unconscious of being observed; but it had probably been learned from Mr. Murray.

At noon I landed to take an observation of the sun, which gave 38° 7′ 6″ for the latitude; my position being nearly at the northern extremity of Indented Head.  Some bearings were taken from the brow of a hill a little way back; and after a dinner of which the natives partook, we left them on friendly terms to proceed westward in our examination.  The water became very shallow abreast of a sandy point, whence the shore trends nearly south-west; and there being no appearance of an opening to the sea this way, I steered across the western arm, as well to ascertain its depth as with the intention of ascending the hills lying behind the northern shore.  Two of the peaks upon these hills had been set from the ship’s deck at sunset of the 25th, at the distance of thirty-seven miles; and as their elevation must consequently be a thousand feet, or more, I expected to obtain from thence such a view of the upper parts of the port as would render the coasting round it unnecessary.

The width of the western arm was found to be six miles; and the soundings across augmented regularly to 6 fathoms in mid channel, and then decreased in the same way; but there was less than 3 fathoms at two miles from the northern shore.  That side is indeed very low and marshy, with mud banks lying along it; and we had difficulty in finding a dry place to pitch the tent, and still more to procure wood wherewith to cook the ducks I had shot upon the banks.


At day dawn I set off with three of the boat’s crew for the highest part of the back hills called Station Peak.  Our way was over a low plain, where the water appeared frequently to lodge; it was covered with small-bladed grass, but almost destitute of wood, and the soil was clayey and shallow.  One or two miles before arriving at the feet of the hills we entered a wood where an emu and a kangaroo were seen at a distance; and the top of the peak was reached at ten o’clock.  My position was then 21′ of latitude from Point Nepean, in the direction of N. 28° 30′ W., and I saw the water of the port as far as N. 75° E., at the distance of seven or eight leagues; so that the whole extent of the port, north and south, is at least thirty miles.  The extremity of the western arm bore S. 15° 45′ W., which makes the extent, east and west, to be thirty-six miles; but there was no communication with the sea on that side, nor did the western arm appear to be navigable beyond seven miles above where I had crossed it.  Towards the interior there was a mountain bearing N. 11° E., eleven leagues distant; and so far the country was low, grassy and very slightly covered with wood, presenting great facility to a traveller of penetrating inland.

I left the ship’s name on a scroll of paper, deposited in a small pile of stones upon the top of the peak; and at three in the afternoon reached the tent, much fatigued, having walked more than twenty miles without finding a drop of water.  Mr. Lacy, the midshipman of the boat, had observed the latitude at the tent from an artificial horizon to be 38° 2′ 22″; and Station Peak bore from thence N. 47° W.

In the evening we rowed back to Indented Head, and landed there soon after dark.  Fires had been seen moving along the shore, but the people seemed to have fled; though we found two newly erected huts with fires in them, and utensils, which must have belonged to some of the people before seen, since there was boiled rice in one of the baskets.  We took up our quarters here for the night, keeping a good watch; but nothing was seen of the Indians till we pushed off from the shore in the morning [SUNDAY 2 MAY 1802], when seven showed themselves upon a hill behind the huts.  They ran down to examine their habitations, and finding every thing as they had left it, a little water excepted of which we were in want, they seemed satisfied; and for a short time three of them followed the boat.

Along the north-east and east sides of Indented Head I found the water to be shoal for nearly a mile off; but on approaching the entrance of what Mr. Murray called Swan Harbour, but which I have taken the liberty to converting into Swan Pond, it became somewhat deeper.  Seeing swans there, I rowed into it after them, but found the place full of mud banks, and seldom more than three or four feet in depth.  Three of the birds were caught; and at the south side of the entrance, upon the sandy peninsula, or island as it is when the tide is in, I shot some delicate teal, and found fresh water in small ponds.

The ship was lying about three miles within the mouth of the port, near to the south shore; and after I had taken bearings at two stations on the sandy peninsula, we steered a straight course for her, sounding all the way.  It appeared that there was a passage up the port of a mile wide between the middle banks and the western shore, with a depth in it from 3 to 4½ fathoms.  On the western extremity of the banks I had 2½ fathoms, and afterwards 5, 7, 4, 7, 8, 9, 9 to the ship.

Lieutenant Fowler had had a good deal of difficulty in getting back to the entrance of the port; owing in part to the western winds, and partly from the shoals, which do not seem to lie in any regular order.  He had touched upon one of these, where there was ten feet on one side of the ship, and on the other 5 fathoms.  This seems to have been a more eastern part of the same shoal upon which we had before grounded; but no danger is to be feared from these banks to a flat-floored ship.

I find it very difficult to speak in general terms of Port Phillip.  On the one hand it is capable of receiving and sheltering a larger fleet of ships than ever yet went to sea; whilst on the other, the entrance, in its whole width, is scarcely two miles, and nearly half of it is occupied by the rocks lying off Point Nepean, and by shoals on the opposite side.  The depth in the remaining part varies from 6 to 12 fathoms; and this irregularity causes the strong tides, especially when running against the wind, to make breakers, in which small vessels should be careful of engaging themselves; and when a ship has passed the entrance, the middle shoals are a great obstacle to a free passage up the port.  These shoals are met with at four miles directly from the entrance, and extend about ten miles to the east-south-east, parallel with the south shore; they do not seem, however, to be one connected mass, for I believe there are two or three deep openings in them, though we had not time to make an examination.

No runs of fresh water were seen in any excursions; but Mr. Charles Grimes, surveyor-general of New South Wales, afterwards found several, and in particular a small river falling into the northern head of the port.  Mr. Grimes was sent by governor King, in 1803, to walk round, and survey the harbour; and from his plan I have completed my chart of Port Phillip.  The parts of the coast left unshaded are borrowed from him, and the soundings written at right angles are those of his companion, lieutenant Robbins.

The country surrounding Port Phillip has a pleasing, and in many parts a fertile appearance; and the sides of some of the hills and several of the vallies are fit for agricultural purposes.  It is in great measure a grassy country, and capable of supporting much cattle, though better calculated for sheep.  To this general description there are probably several exceptions; and the southern peninsula, which is terminated by Point Nepean, forms one, the surface there being mostly sandy, and the vegetation in many places little better than brush wood.  Indented Head, at the northern part of the western peninsula, had an appearance particularly agreeable; the grass had been burned not long before, and had sprung up green and tender; the wood was so thinly scattered that one might see to a considerable distance; and the hills rose one over the other to a moderate elevation, but so gently that a plough might every where be used.  The vegetable soil is a little mixed with sand, but good, though probably not deep, as I judged by the small size of the trees.

The most common kinds of wood are the casuarina and eucalyptus, to which Mr. Grimes adds the banksia, mimosa and some others; but the timber is rarely sound, and is not large.

Were a settlement to be made at Port Phillip, as doubtless there will be some time hereafter, the entrance could be easily defended; and it would not be difficult to establish a friendly intercourse with the natives, for they are acquainted with the effect of fire-arms and desirous of possessing many of our conveniences.  I thought them more muscular than the men of King George’s Sound; but, generally speaking, they differ in no essential particular from the other inhabitants of the South and East Coasts except in language, which is dissimilar, if not altogether different to that of Port Jackson, and seemingly of King George’s Sound also.  I am not certain whether they have canoes, but none were seen.

In the woods are the kangaroo, the emu or cassowary, paroquets, and a variety of small birds; the mud banks are frequented by ducks and some black swans, and the shores by the usual sea fowl common in New South Wales.  The range of the thermometer was between 61° and 67°; and the climate appeared to be as good and as agreeable as could well be desired in the month answering to November.  In 1803, colonel Collins of the marines was sent out from England to make a new settlement in this country; but he quitted Port Phillip for the south end of Van Diemen’s Land, probably from not finding fresh water for a colony sufficiently near to the entrance.

Point Nepean is in latitude 38° 18′ south.  The longitude from twelve sets of distances taken by lieutenant Flinders in the port, and six others by me ten days before arriving, the particulars of which are given in Table V of the Appendix to this volume, is 144° 30½’ east; but these observations being mostly on one side of the moon, the corrected longitude by time keepers, 144° 38′ east, is preferred.

No observations were taken in the port for the variation of the compass; but at seven leagues to the south-south-west of Point Nepean, azimuths gave 3° 41′ when the ship’s head was at N.E. by E. ½ E., and an amplitude at N. N. E. ½ E., 6° 48′ east.  The mean of these, corrected to the meridian, will be 7° 30′, or half a degree less than at King’s Island; I therefore take the variation in Port Phillip to have been generally, 7°, though at some stations it seemed to have been no more than 6° 30′ east.

The rise of tide is inconsiderable in the upper parts of the port; near the entrance it is from three to six feet.  By the swinging of the ship, which, however, varied at different anchorages, it appeared to be high water two hours and a half after the moon’s passage; but at Point Nepean the time of high water by the shore is said by Mr. Grimes to be only one hour after the moon.  At Western Port, Mr. Bass found high water to take place half an hour after the moon’s passage, and the tide to rise from ten to fourteen feet. This great increase, in a place so near, seems extraordinary; but may perhaps be accounted for by the meeting of the tides from two entrances, whilst Port Phillip has only one, and that very narrow . . .”

The Brilliance of Matthew Flinders

It is important to note that Matthew Flinders was the first to circumnavigate Australia.  He charted and mapped this journey to an incredible level of accuracy with the most basic of instruments.  He returned to Sydney in the June of 1803.  He had overcome tremendous challenges including the fact that his ship, H.M. Survey Sloop ‘Investigator’ in which he completed this miraculous feat, was barely seaworthy – leaking, requiring constant repair, endangering the lives of himself and his crew – incidents of which he writes many times in his journal.

And yet, his maps were so incredibly accurate.  They were used well into the 20th Century.

Sadly, during his return voyage to England, Matthew Flinders was captured and imprisoned by the French at Port Louis, Mauritius on the 17th December 1803.  Held under the guise of he being a spy, he remained a prisoner on the island until the 13th June 1810.  The imprisonment took a heavy toll on his health, he returned to England frail and ill – his wife described to a friend that he was “worn to a skeleton”.  Miraculously, he managed to complete his book, however, would not live see it in print.

The first copy was delivered to him the day before he died.  He was, however, deeply unconscious by this stage . . .

He died the very next day, on the 19th July 1814, aged just 40 years old . . .

“The excellence of his charts was such that to this day the Admiralty charts for those portions of the Australian coast where he did original work bear upon them the honoured name of Matthew Flinders; and amongst the seamen who habitually traverse these coasts, no name, not even that of Cook, is so deeply esteemed as his.  Flinders is not a tradition; the navigators of our own time count him a companion of the watch.”

Matthew Flinders’  ‘Hat Rock’

1797 – 1 oz Cart Wheel Suppence – found at 16 Drysdale Street, Portarlington

A rare 1797, 1 oz Cart Wheel Suppence was found by Evan McKenzie at 16 Drysdale Street, in Portarlington.  Could this remarkable find be a lost item left behind by Matthew Flinders or one of his team whilst wandering over this area in 1802 ??? . . .  According to his journal, Matthew Flinders’ had camped at this location which he had named ‘Hat Rock‘ . . .

Interestingly, this same location could also possibly be where John Batman’s crew set up camp 33 years later – whilst he hurriedly returned to ‘Van Diemen’s Land’ (now Tasmania) to report his discoveries and the treaties he had made with the Aborigines.  John Batman’s voyage would lead to the rapid establishment and growth of the capital city of VictoriaMelbourne, from late 1835 . . .

Batman's Camp - NW Corner Indented Head” . . . After breakfast the wind shifted to the southward, and the ‘Henry’ brig, from Launceston, Captain Whiting, ran in, bound to Point Henry with sheep; but before Mills and his men could get away from Mud Island the brig had passed.  They pulled and sailed after her but did not overtake her until she arrived off the point where Batman first settled, now called Port Arlington; at that time they called the place Indented Heads. . . “

The article titled ‘Early Victoria – Work of Batman’s Party – Diary of William Todd’, published in the ‘Examiner’ on the 7th March 1905, also notes the location of Batman’s first encampment in Port Phillip as:

” . . . Todd was one of the three white men left by Batman at Indented Head, Port Phillip (on the N.W. corner of the Queenscliff peninsula), while he went back to Tasmania . . . “
