The position and extent of Port Curtis, which I take to be the third harbour in importance in these seas, inferior only to Port Jackson and Hobart Town, must shortly lead to an establishment on its shore, offering security to numerous whaling vessels, which are now compelled to proceed to Sydney for repairs and supplies; it must also become an important depot for supplying steamers on passage to India with coal, which I have reason to believe will be found in abundance within a few miles of the coast. I have no doubt also that this port will become celebrated for shipbuilding, possessing, as it does, timber of the highest quality for such purposes, and favourable positions for building, as well as for the construction of docks. The country is capable of affording all the tropical, as well as a considerable portion of European produce, and will be found highly favourable for the breeding of stock; indeed, I believe I am correct in stating that numerous parties, with stock to a very large amount, are now within a short distance of Port Curtis, taking up stations, not only with a view to the supply of the projected settlement, but also to the shipment of wool, tallow, etc. direct to England. ... PASSAGE OF THE ASP. A few days after our arrival at Port Curtis, the Asp, as our decked boat had been named, joined us, having made an important addition to the surveys of this portion of the coast. On his passage up from Brisbane, Lieutenant Dayman, under the unexpected circumstances of finding that the Rattlesnake had sailed, instead of coasting along the eastern side of Great Sandy Island, thus involving the necessity of rounding Breaksea Spit, determined upon trying the passage between that island and the mainland leading into Hervey Bay; this he fortunately succeeded in accomplishing, although under difficulties which his sketch (since published by the Admiralty) will lessen to those who may require to use the same previously little known channel. Port Curtis, comprising a space of about ten miles in length, is enclosed between Facing Island on the east, or to seaward, Curtis Island on the north, and the shores of the mainland on the western side, leaving to the southward a wide entrance partially blocked up by shoals. Besides the narrow channel described by Flinders as leading between the south end of Facing Island and the large bank of shoal water extending about six miles to the south-east, a second, and much safer one, the least width of which is upwards of a mile, was discovered between the large bank and others of less extent towards the mainland.
