What states border the Tasman Sea?

The states bordering the Tasman Sea are New South Wales, Victoria, and Tasmania. Their eastern and southern coastlines all face the Tasman, the arm of the Pacific Ocean separating Australia from New Zealand.

New South Wales has the longest Tasman coastline of the three at about 2,137 kilometres, stretching from Tweed Heads on the Queensland border in the north to Cape Howe in the far south. The coast includes major centres such as Sydney, Newcastle, Wollongong, Coffs Harbour, and Eden, and is lined with surf beaches, headlands, estuaries, and national parks including Royal, Ku-ring-gai Chase, and Booderee.

Victoria's Tasman coast runs from the New South Wales border at Cape Howe around to Wilsons Promontory and along the Bass Strait coast to South Australia. Bass Strait is officially part of the Tasman Sea, separating Victoria from Tasmania across about 240 kilometres of often-rough water. Major Victorian Tasman coastal centres include Lakes Entrance, Phillip Island, and the Mornington Peninsula.

Tasmania has Tasman Sea coastline on its east and south, including Hobart, the Tasman Peninsula and the historic Port Arthur penal site, the Bay of Fires, Freycinet National Park, and Wineglass Bay. The Sydney to Hobart Yacht Race, sailed every Boxing Day, crosses the Tasman from north to south and finishes in Hobart on the Derwent River. Trans-Tasman ferries operate between Geelong and Devonport, and weather patterns crossing the Tasman from west to east drive much of the cool, wet weather of southern Australia and the warm, dry weather of New Zealand. Queensland's southern coast technically ends at the New South Wales border at Tweed Heads, where the Tasman becomes the Coral Sea further north.
