The best time for passing up this coast is in April and the beginning of May, or between the middle of August and latter end of October; in the months of June and July, the passage is not apparently so safe, on account of the changeable weather that may be encountered, which to a stranger would create much anxiety, although no real danger. Strict attention to these directions and confidence in the chart, with a cautious lookout will, however, neutralize all the dangers that thick weather may produce in this navigation. The tides and currents in this part are not of much consequence. The rise of tide is trifling, the flood-tide sets to the North-West, but at a very slow rate. In the neighbourhood of the reefs, the stream sometimes sets at the rate of a knot or in some cases at two knots, but for a small distance it is scarcely perceptible. There appeared rather to be a gentle drain of current to the North-West. HERVEY'S BAY and BUSTARD BAY have been already described by Captains Cook and Flinders. We did not enter either, so that I have nothing to offer in addition to the valuable information of those navigators (Hawkesworth volume 3 page 113 and 117; and Flinders Introduction cci. and volume 2 page 9 et seq.) LADY ELLIOT'S ISLAND is a low islet, covered with shrubs and trees, and surrounded by a coral reef, which extends for three-quarters of a mile from its north-east end; the island is not more than three-quarters of a mile long, and about a quarter of a mile broad; it is dangerous to approach at night, from being very low. It is situated thirty miles North 53 degrees West (magnetic) from the extremity of Breaksea Spit (as laid down in Captain Flinders' chart); its latitude is 24 degrees 6 minutes, and its longitude 152 degrees 45 minutes 15 seconds. BUNKER'S GROUP consists of three islets; they are low and wooded like Lady Elliot's Island, and lie South-East and North-West from each other; the south-easternmost (or 1st) has a coral reef projecting for two miles and a half to the North-East: four miles and a half to the North-West of the north-westernmost (or 3rd islet) is a large shoal, which, from the heavy breakers upon it, is probably a part of the barrier or outer reefs. The centre island (or 2nd) of the group is in latitude 23 degrees 51 minutes 10 seconds, and longitude 152 degrees 19 minutes 5 seconds. Off the south-west end of the 2nd island is a small detached islet connected to it by a reef; and off the north-east end of the 3rd island is another islet, also connected by a coral reef. The spaces between these islands, which are more than a league wide, are quite free from danger: we passed within a quarter of a mile of the south end of the reef off the 3rd island, without getting bottom with ten fathoms.
