World Heritage Places - Willandra Lakes Region
New South Wales
The Willandra Lakes Region is an extensive area that contains a system of ancient lakes formed over the last two million years, most of which are fringed by a crescent shaped dune or lunette. Aborigines lived on the shores of the lakes for at least 50,000 years, and the remains of a 40,000 year old female found in the dunes of Lake Mungo are believed to be the oldest ritual cremation site in the world.
The Willandra Lakes Region was inscribed on the World Heritage List in 1981. The original boundary of the World Heritage Property was modified in 1995 in order to better define the area containing the World Heritage values.
The Willandra Lakes Region was one of 15 World Heritage places included in the National Heritage List on 21 May 2007.

The Willandra Lakes Region covers 2,400 km2 of a semi-arid landscape mosaic in the Murray Basin area of far south western New South Wales. It comprises dried saline lake bed plains vegetated with saltbush communities, fringing sand dunes and woodlands with grassy understoreys.
Description of Place
The region contains a system of Pleistocene lakes, formed over the last two million years. These lakes are now dry. Most are fringed on the eastern shore by a crescent-shaped dune, referred to as a ‘lunette’, that was formed by the prevailing winds.
Today, the lake beds are flat plains vegetated by salt tolerant low bushes and grasses. Part of the World Heritage property is gazetted as the Mungo National Park, which covers about two-thirds of Lake Mungo and includes the spectacular parts of the Walls of China lunette. The remaining area comprises pastoral leasehold properties. Joulni Station at the southern end of the Mungo lunette is of cultural significance to the three Traditional Tribal Groups.
There are five large, interconnected, dry lake basins and 14 smaller basins varying in area from 6 to 350 km 2. The original source for the lakes was a creek flowing from the Eastern Highlands to the Murray River. When the Willandra Billabong Creek ceased to replenish the lakes, they dried in series from south to north over a period of several thousand years, each becoming progressively more saline.
The ancient shorelines are stratified into three major layers of sediments that were deposited at different stages in the lakes' history.
The lakes were full of deep, relatively fresh water for a period of 30,000 years that came to an end 19,000 years ago. The earliest sediments are more than 50,000 years old and are orange-red in colour. Above are clays, clean quartz sand and soil that were deposited along the lakes' edges when the lakes were full. The top layer is composed largely of wind-blown clay particles heaped up on the lunettes during periods of fluctuating water levels, before the lakes finally dried up.
Indigenous people have lived in the Willandra Lakes Region for at least 50,000 years. Excavations in 1968 uncovered the cremated remains of ‘Mungo Lady’ in the dunes of Lake Mungo. At 40,000 years old, this is believed to be the oldest site of ritual cremation in the world. In 1974, the ochred burial of a male Aborigine was found nearby. The skeleton, known as ‘Mungo Man’, is believed to be 40,000 years old.
In 2003, nearly 460 fossilised human footprints were discovered, the largest collection of its kind in the world. The prints were made by children, adolescents and adults 19,000 to 23,000 years ago in wet clay. The clay, containing calcium carbonate, hardened like concrete, and a layer of clay and sand protected the prints.
During the last Ice Age, when the lakes were full, the Mungo people camped along the lake shore, taking advantage of a wide range of food including freshwater mussels, yabbies, golden perch and Murray cod, large emus and a variety of marsupials, which probably included the now extinct giant kangaroos. They also exploited plant resources, particularly when the lakes began to dry and food was less abundant.
The human history of the region is not restricted just to an ancient episode. Evidence so far points to an extraordinary continuity of occupation over long periods of time. In the top layers of sediments there is abundant evidence of occupation over the last 10,000 years.
The vegetation in the region, sparse though it is, is typical of the semi-arid zone. It plays an important role in stabilising the landscape and hence maintaining its sediment strata and many species of native fauna.
Small scrubby multi-stemmed mallee eucalypts are found on the dunes, with an understorey of herbs and grasses. Rosewood-belah woodland is common on the sand plains. In the lake beds, several species of saltbush are able to thrive in the saline conditions.
The remains of a large number of animals have been found in the Willandra Lakes Region. More than 55 species have been identified, 40 of which are no longer found in the region, and 11 of which are extinct.
Twenty-two species of mammals are currently recorded. Bats are the most diverse group, and there are some 40 species of reptiles and amphibians.
The bird life of the Willandra Lakes Region is similar to that in many other semiarid areas of Australia. Parrots, cockatoos and finches are the most conspicuous of the 137 recorded species.
