The Bass Strait Triangle is the waters that separate the states of Victoria and Tasmania, including Bass Strait, in south-eastern Australia. The term Bass Strait Triangle (inspired by the Bermuda Triangle) appears to have been first used [lower-alpha 1] following the disappearance of Frederick Valentich in 1978 although the region had a bad reputation (never ascribed to supernatural forces, however) long before that.

Geography of Bass Strait

Bass Strait is a generally shallow (average depth of 50 m (160 ft)) stretch of water approximately 300 km (190 mi) wide and 200 km (120 mi) from north to south, encompassed by the entire northern coastline of Tasmania and Victoria's central to eastern coast. The prevailing winds and currents are westerly, the latter being divided by King Island, Tasmania at the western entrance to the strait, causing unpredictable sea conditions, especially when strong winds occur. For example, strong southerly winds can cause a strong northerly current reflecting from the Victorian coast. The combination of winds, currents, tidal flow and the shallow bottom often lead to tall waves, often of short length, with a confused short swell often conflicting in direction.

All shipping to the busy ports of Melbourne, Stanley, Burnie, Devonport, Bell Bay and Launceston and the Bass Strait islands such as King Island and Flinders Island must pass through Bass Strait, and it is also the route of choice for many ships passing from the Australian west to east coasts. Most air traffic between Tasmania and the Australian mainland flies at least in part over or adjacent to it. [1]

Incidents

Bass Strait was discovered following the wreck of the ship Sydney Cove on the Furneaux Group in 1797 and one of the vessels engaged in the salvage operation, the sloop Eliza, went missing on her return voyage to Sydney. [2] Hundreds of vessels from small yachts and fishing craft 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 a trace. [3] [ page needed ]

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.
