Tasmania and Victoria were separated by the foundering of Bass Strait, and at the same time the formation of the rift valley of Spencer Gulf, and Lake Torrens, isolated the South Australian highlands from the Eyre Peninsula and the Westralian plateau.
But they have been separated by the foundering of the Coral Sea and the Tasman Sea, which divided the continent of Australia from the islands of the Australasian festoon; and the foundering of the band across Australia, from the Gulf of Carpentaria, through western Queensland and western New South Wales, to the lower basin of the Murray, has separated the Archean areas of eastern and western Australia.
Nor were the new ships a great success, as we hear of them grounding in action and foundering in a storm.
It is most intimately connected with Victoria, from which it was only separated by the foundering of Bass's Strait in late Pliocene or early Pleistocene times.
Now, gentlemen, sweeping a ship's deck at sea is a piece of household work which in all times but raging gales is regularly attended to every evening; it has been known to be done in the case of ships actually foundering at the time.
