The TASMAN SEA (Māori : Te Tai-o-Rehua ) is a marginal sea of the South Pacific Ocean , situated between Australia
and New Zealand
New Zealand
. It measures about 2,000 kilometres (1,200 mi) across and about 2,800 kilometres (1,700 mi) from north to south. The sea was named after the Dutch explorer Abel Janszoon Tasman , who was the first recorded European to encounter New Zealand
New Zealand
and Tasmania
. The British explorer Captain James Cook
James Cook
later extensively navigated the Tasman Sea
Tasman Sea
in the 1770s as part of his first voyage of exploration.

The Tasman Sea
Tasman Sea
is informally referred to in both Australian and New Zealand English as THE DITCH; for example, crossing the Ditch means travelling to Australia
from New Zealand, or vice versa. The diminutive term "The Ditch" used for the Tasman Sea
Tasman Sea
is comparable to referring to the North Atlantic Ocean as "The Pond".

; beyond this Island a line running to the Eastward of the Vansittart Shoals to Barren Island , and from Cape Barren (the Easternmost point of 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 .

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.

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.


The Tasman Sea

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.
