The Tasman Sea is a marginal sea of the South Pacific Ocean between Australia and New Zealand, approximately 2,000 kilometres (1,200 mi) across. It extends 2,800 km (approx.) from north to south. The sea was named after the Dutch explorer Abel Janszoon Tasman, the first recorded European to encounter New Zealand and Tasmania. The British explorer Captain James Cook later extensively navigated the Tasman Sea in the 1770s as part of his first voyage of exploration.[1]

The Tasman Sea is commonly referred to in both Australia and New Zealand as The Ditch; for example, crossing the ditch means going to Australia from New Zealand or vice versa. In Māori, the Tasman Sea is called Te Tai-o-Rehua.[2]

Geography[edit]

Extent[edit]

The International Hydrographic Organization defines the limits of the Tasman Sea as follows:[3]

On the West. A line from Gabo Island (near Cape Howe, 37°30'S) to the Northeast point of East Sister Island (148°E) thence along the 148th meridian to Flinders Island; beyond this Island a line running to the Eastward of the Vansittart Shoals to [Cape] Barren Island, and from Cape Barren (the Easternmost point of [Cape] Barren Island) to Eddystone Point (41°S) in Tasmania, thence along the East coast to South East Cape, the Southern point of Tasmania.

On the North. The parallel of 30°S from the Australian coast Eastward as far as a line joining the East extremities of Elizabeth Reef and South East Rock (31°47′S 159°18′E / 31.783°S 159.300°E / -31.783; 159.300) then to the Southward along this line to the South East Rock [an outlier of Lord Howe Island].

On the Northeast. From the South East Rock to the North point of Three Kings Islands (34°10′S 172°10′E / 34.167°S 172.167°E / -34.167; 172.167) thence to North Cape in New Zealand.

On the East.

On the Southeast. A line running from South West Cape, Stewart Island, through The Snares (48°S, 166°30'E) to North West Cape, Auckland Island (50°30′S 166°10′E / 50.500°S 166.167°E / -50.500; 166.167), through this island to its Southern point.

On the South. A line joining the Southern point of Auckland Island (50°55′S 166°0′E / 50.917°S 166.000°E / -50.917; 166.000) to South East Cape, the Southern point of Tasmania.

Ridge[edit]

The Tasman Sea's mid-ocean ridge developed between 85 and 55 million years ago as Australia and Zealandia broke apart during the breakup of supercontinent Gondwana. It lies roughly midway between the continental margins of Australia and Zealandia. Much of Zealandia is submerged, so the ridge runs much closer to the Australian coast than New Zealand's.

Islands[edit]

The Tasman Sea features a number of mid-sea island groups, quite apart from coastal islands located near the Australian and New Zealand mainlands:

History[edit]

Moncrieff and Hood were the first to attempt to a Trans-Tasman crossing by plane in 1928. The first successful flight over the sea was accomplished by Charles Kingsford Smith later that year. The first person to row solo across the sea was Colin Quincey in 1977. The next successful solo crossing was completed by his son, Shaun Quincey in 2010.[4]
