One of the most complex of the many fiords on this coast, it is also one of the largest, 40 kilometres in length and eight kilometres wide at its widest point. To the north of its mouth is the large Resolution Island, whose Five Fingers Peninsula shelters the mouth of the sound from the northwest; along the east coast of the island, Acheron passage connects Dusky Sound with Breaksea Sound, to the north.
Several large islands lie in the sound, notably Anchor Island, Long Island, and Cooper Island. The upper reaches of the sound are steep-sided, and the high precipitation of the region leads to hundreds of waterfalls cascading into the sound during the rainy season. Seals and dolphins are often sighted in the sound's waters and occasionally visited by whales where the area especially nearby Preservation Inlet was one of earliest shore-based whaling ground for southern right whales, while humpback whales show sudden increases. The Seaforth River is the largest of many small rivers and creeks which flow into the sound.
Important Bird Area
The inlet was first sighted by Europeans and Captain Cook noted its entrance during his first voyage to New Zealand in 1770. He named it Dusky Bay. On his second expedition he spent two months exploring the sound, and used it as a harbour, establishing workshops and an observatory. It is believed his crew brewed the first beer in New Zealand during his stay. He encountered some Maori with whom he had friendly relations. Later they seemed to have disappeared and it was speculated their countrymen had killed them, perhaps for the presents Cook gave them.
Cook saw the place as a good harbour for ships entering the Pacific from Europe by the shortest route, highlighting its maritime significance and overlooking its land-locked character. This gave it an unusual prominence in earliest European visits which disappeared as Europeans became more familiar with New Zealand's geography.
Dusky was consequently used as a harbour by other European navigators and merchant ships in the late 18th and early 19th centuries. From 1792 it became a favoured site for seal hunters. Men landed by Captain William Raven from the Britannia in that year built the first European house in New Zealand and the first ship in Australasia, and the first European woman known to have been in New Zealand was recorded as a visitor in 1793. A group of 244 Europeans was stranded in Dusky Sound in 1795, which included two women, Elizabeth Bason and Ann Carey, the first known to have lived ashore. The last of this group left in 1797. The attention of the sealers moved to Bass Strait from 1798 but returned to New Zealand, at Dusky Sound, from 1802. In that year Captain Charles Bishop and George Bass in the Venus spent 14 days in Dusky Sound stripping iron from the hulk of Captain Brampton's old ship the Endeavour. The blacksmith converted the iron into axes which they then used in Tahiti to trade for pork before returning to Sydney by November 1802. Following this, in January 1803, George Bass asked Governor King of New South Wales for a fishing monopoly, from a line bisecting New Zealand from Dusky Sound to Otago Harbour extending south to include the subantarctic Islands. It was not granted, but it indicates the sealers' area of interest and Dusky Sound's place in it. The Matilda under Captain Fowler was on this part of the coast in 1814 when six of his lascar (Indian) seamen absconded in an open boat. It seems it was at Dusky Sound they were set upon by Maori when three were killed and eaten and the others enslaved. One or more of them later lived in what is now the Dunedin district. Sealers continued to visit until the late 1820s when the second sealing boom faded.
An attempt was made in 1903 to construct a road from Dusky Sound to Lake Manapouri, but it was never completed, terminating abruptly on the western side of Loch Maree.
