Geography of Bass Strait

Bass Strait is a generally shallow (average depth of 30 m (98.4 ft)) stretch of water approximately 300 km (186.4 mi) wide and 200 km (124.3 mi) from north to south, encompassed by the entire northern coastline of Tasmania and central to eastern coast of Victoria. The prevailing winds and currents are westerly, the latter being divided by King Island, Tasmania

 Eliza, went missing on her return voyage to Sydney. Hundreds of vessels up to the size of bulk carriers have come to grief in Bass Strait since that time through hitting reefs, running aground on the coastline or on river bars while entering port, or foundering due to stress of weather, some dozens being lost without trace.

Actual north-south (and vice versa) crossing of Bass Strait seldom occurred until after Melbourne was established in 1835. From 1838-1840, at least seven vessels were lost with all hands on their way to or from the new settlement, wreckage from only three being identified. Rumours that some of these vessels had fallen victim to wreckers

 appear baseless, the main cause probably being bad weather and poor charts. Over the next 100 years, dozens of other vessels have gone missing after entering the Straits, many without trace. One of the most significant disappearances was that of the British warship in 1858, in which well over one hundred lives were lost.

 Miss Hobart, went missing soon after entering service in 1934, only a small amount of wreckage being found on the Victorian coast.
