The bay affords a convenient place for wooding and watering; the latter may be had during the early months of the dry season (as late as August) from a drain at the base of the Pipe Clay Cliffs at the north end of the bay.

There are also some holes on Sims Island that contain water for a much later period.

The holes have been made by the Malays for the purpose of collecting it.
MULLET BAY is on the west side of the north island, affording good anchorage in the easterly monsoon in six and seven fathoms mud, at a mile from the shore.

The flood-tide here sets to the eastward, and it is high water at full and change in the strait at six o'clock; the rise of the tide is not more than five or six feet.

The north-east point of North Goulburn Island is in latitude 11 degrees 26 minutes, longitude 133 degrees 26 minutes.
From Macquarie Strait the land trends to the westward, and north-westward to De Courcy Head, and forms but few sinuosities.
