History
The sand dune system responsible for the formation of the estuary began about 7,000 years ago. At this time the coast section between Mandurah and Bunbury was an open rocky limestone shore. A dune system began to build on the shore forming a long barred estuarine lagoon between the current estuary as far north as Lake Preston and effectively separated the lagoon from the ocean.
About 4,500 years ago the dune system met up with the eastern shore of the estuary separating the lagoon into two sections. The northern portion filled with mud leaving the southern section as the estuary that exists today.
Construction of the 'Cut', which opens the estuary into the ocean opposite the Collie River mouth, commenced in February 1950.

“Postmodernism is, almost by definition, a transitional cusp of social, cultural, economic and ideological history when modernism’s high-minded principles and preoccupations have ceased to function, but before they have been replaced with a totally new system of values. It represents a moment of suspension before the batteries are recharged for the new millennium, an acknowledgment that preceding the future is a strange and hybrid interregnum that might be called the last gasp of the past.”
—Gilbert Adair, British author, critic. Sunday Times: Books (London, April 21, 1991)
“The greatest horrors in the history of mankind are not due to the ambition of the Napoleons or the vengeance of the Agamemnons, but to the doctrinaire philosophers. The theories of the sentimentalist Rousseau inspired the integrity of the passionless Robespierre. The cold-blooded calculations of Karl Marx led to the judicial and business-like operations of the Cheka.”
—Aleister Crowley (1875–1947)
