The south-east coast of Van Diemen’s Land, from the solitary Mewstone to the basaltic cliffs of Tasman’s Head, from Tasman’s Head to Cape Pillar, and from Cape Pillar to the rugged grandeur of Pirates’ Bay, resembles a biscuit at which rats have been nibbling. Eaten away by the continual action of the ocean which, pouring round by east and west, has divided the peninsula from the mainland of the Australasian continent-and done for Van Diemen’s Land what it has done for the Isle of Wight-the shore line is broken and ragged. Viewed upon the map, the fantastic fragments of island and promontory which lie scattered between the South–West Cape and the greater Swan Port, are like the curious forms assumed by melted lead spilt into water. If the supposition were not too extravagant, one might imagine that when the Australian continent was fused, a careless giant upset the crucible, and spilt Van Diemen’s land in the ocean. The coast navigation is as dangerous as that of the Mediterranean. Passing from Cape Bougainville to the east of Maria Island, and between the numerous rocks and shoals which lie beneath the triple height of the Three Thumbs, the mariner is suddenly checked by Tasman’s Peninsula, hanging, like a huge double-dropped ear-ring, from the mainland. Getting round under the Pillar rock through Storm Bay to Storing Island, we sight the Italy of this miniature Adriatic. Between Hobart Town and Sorrell, Pittwater and the Derwent, a strangely-shaped point of land — the Italian boot with its toe bent upwards — projects into the bay, and, separated from this projection by a narrow channel, dotted with rocks, the long length of Bruny Island makes, between its western side and the cliffs of Mount Royal, the dangerous passage known as D’Entrecasteaux Channel. At the southern entrance of D’Entrecasteaux Channel, a line of sunken rocks, known by the generic name of the Actaeon reef, attests that Bruny Head was once joined with the shores of Recherche Bay; while, from the South Cape to the jaws of Macquarie Harbour, the white water caused by sunken reefs, or the jagged peaks of single rocks abruptly rising in mid sea, warn the mariner off shore.
It would seem as though nature, jealous of the beauties of her silver Derwent, had made the approach to it as dangerous as possible; but once through the archipelago of D’Entrecasteaux Channel, or the less dangerous eastern passage of Storm Bay, the voyage up the river is delightful. From the sentinel solitude of the Iron Pot to the smiling banks of New Norfolk, the river winds in a succession of reaches, narrowing to a deep channel cleft between rugged and towering cliffs. A line drawn due north from the source of the Derwent would strike another river winding out from the northern part of the island, as the Derwent winds out from the south. The force of the waves, expended, perhaps, in destroying the isthmus which, two thousand years ago, probably connected Van Diemen’s Land with the continent has been here less violent. The rounding currents of the Southern Ocean, meeting at the mouth of the Tamar, have rushed upwards over the isthmus they have devoured, and pouring against the south coast of Victoria, have excavated there that inland sea called Port Philip Bay. If the waves have gnawed the south coast of Van Diemen’s Land, they have bitten a mouthful out of the south coast of Victoria. The Bay is a millpool,............
