Sunday, 3rd, June 1770

Winds between the South by East and South-East. A Gentle breeze and Clear weather. In the P.M. we steer'd along shore North-West 1/2 West, at the distance of 2 Leagues from the Main, having 9 and 10 fathoms regular soundings. At sun set the furthest point of the Main Land that we could distinguish as such bore North 48 degrees West; to the Northward of this lay some high land, which I took to be an Island, the North West point of which bore North 41 degrees West; but as I was not sure that there was a passage this way, we at 8 came to an Anchor in 10 fathoms, muddy bottom. 2 hours after this we had a tide setting to the Northward, and at 2 o'clock it had fallen 9 Feet since the time we Anchored. After this the Tide began to rise, and the flood came from the Northward, which was from the Islands out at Sea, and plainly indicated that there was no passage to the North-West; but as this did not appear at day light when we got under Sail, and stood away to the North-West until 8, at this time we discover'd low land, quite a Cross what we took for an Opening between the Main and the Islands, which proved to be a Bay about 5 or 6 Leagues deep. Upon this we hauld our wind to the Eastward round the Northermost point of the Bay, which bore from us at this time North-East by North, distance 4 Leagues. From this point we found the Main land trend away North by West 1/2 West, and a Strait or Passage between it and a Large Island* or Islands laying in a Parrallel direction with the Coast; this passage we Stood into, having the Tide of Ebb in our favour. At Noon we were just within the Entrance, and by observation in the Latitude of 20 degrees 26 minutes South; Cape Hillsborough bore South by East, distant 10 Leagues, and the North point of the Bay before mentioned bore South 19 degrees West, distance 4 Miles. This point I have named Cape Conway** (Latitude 20 degrees 30 minutes, Longitude 211 degrees 28 minutes), and the bay, Repulse Bay, which is formed by these 2 Capes. The greatest and least depth of Water we found in it was 13 and 8 fathoms; every where safe Anchoring, and I believe, was it properly examined, there would be found some good Harbour in it, especially on the North Side within Cape Conway, for just within the Cape lay 2 or 3 Small Islands, which alone would shelter that side of the Bay from the South-East and Southerly winds, which seem to be the prevailing or Trade Winds. Among the many islands that lay upon this Coast there is one more Remarkable than the rest,*** being of a Small circuit, very high and peaked, and lies East by South, 10 Miles from Cape Conway at the South end of the Passage above mention'd.

* Whitsunday Island.

** General H.S. Conway was Secretary of State 1765 to 1768.

*** Probably Blacksmith Island.
