The Nadgee to Mallacoota Inlet Important Bird Area comprises some 385 square kilometres (149 sq mi) of coastal and subcoastal land at the south-eastern corner of the Australian continent, where Cape Howe marks the junction between the Tasman Sea and Bass Strait, as well as the eastern end of the state border between New South Wales and Victoria.
It includes the whole of the 207 square kilometres (80 sq mi) Nadgee Nature Reserve in New South Wales with the adjoining 167 square kilometres (64 sq mi) eastern section of the Croajingolong National Park in East Gippsland, Victoria.
Its temperate coastal vegetation constitutes one of the least disturbed such areas on the mainland of Australia, giving it a nationally significant level of structural and floristic integrity.
[1] The site has been identified by BirdLife International as an Important Bird Area (IBA) because it supports the isolated southernmost population of the endangered eastern bristlebird, with an estimated size of 300 individuals, as well as a population of pilotbirds.
[1] Mammals found in the area include long-nosed potoroos, southern brown bandicoots, yellow-bellied gliders, tiger quolls and dingos.
