It is the northernmost high land from Sydney to the Heads of Port Stephens from which it lies north-east 6 leagues.

The intermediate space being a sandy beach.

The tides both in the harbour and entrance runs very strong, and in some places not less than four miles an hour and sometimes from four to five.

The ebb in general is much stronger than the flood: 9 3/4 hours in the harbour makes high water full and change, and rises six feet perpendicular where the Lady Nelson anchored, and four feet when she was higher up the river.

In the harbour there is good shelter from all winds and plenty of room for more than 100 sail of shipping.
