301 Moved Permanently
Some 25 million years ago the whole of north-west Victoria was submerged beneath a shallow sea. As the seas slowly retreated westerly winds blew sand over the exposed inland areas, building a complex of rolling dunes. The dunes we see today were formed between 40,000 and 15,000 years ago.
Before the arrival of the Europeans, Aboriginal people regularly moved north along Outlet Creek in search of food. Evidence shows that they occupied the area for at least 6000 years, but because of the low and unreliable water supply, they rarely stayed in one place for long.
In 1847, James Clow was the first European to venture along Outlet Creek north of Lake Hindmarsh. He followed the creek to Wirrengren Plain where he established the first pastoral run. Other settlers followed and set about clearing the mallee for grazing and wheat growing.
In 1909, a number of naturalists persuaded the government to temporarily reserve 3900 ha of this fast-disappearing habitat. Wyperfeld National Park was declared in 1921.
