It is on the muddy banks of the Harvey River in the South West where the WACA strikes paydirt for Australia's most menacing bowlers.
The black gold crumbling through the fingers of farmer Mick Muir is the secret weapon that will help send fear through the English batting line-up when the Ashes series comes to Perth on Friday.
The Poms will at least be thankful they are not playing in Dubai, where the clay that makes world cricket's most feared pitch is baking in extreme heat after a United Arab Emirates delegation recently set about replicating the WACA turf.
It is believed the searing Dubai sun has since baked a juiced-up bowling track without peer and some of the clay has been sold to cricket interests in Singapore.
The WACA's historically fast and furious pitch had its unique bounce restored in 2006 when officials decided to go back to the clay patch, on Mr Muir's property, that curator Roy Abbott had once farmed.
The pitches had gradually taken on too much sand compared to clay and then-curator Cam Sutherland wanted to bring back the bounce.
So Mr Muir, who bought the 400ha property two decades ago, became an unlikely cricket saviour.
"I played limited cricket," Mr Muir, a prominent Kalgoorlie mining identity, said. "I had a few seasons of playing country week when I lived up in Carnarvon and I played the occasional game with the Subiaco fourths, fifths or sixths - or however low they went.
"My claim to fame was that I never bothered the scorers very much."
Mr Muir claimed not to have a binding contract with the WACA, rather an "agreement and an understanding". He would not reveal the details.
It is believed a pitch block needs about 100 tonnes of clay.
Mr Muir said that as his mining business interests wound up, he would look at opportunities with the horticulturally conducive clay.
"I've had a quadruple heart bypass, a hip replacement, a number of strokes and stuff like that," he said. "But I'm 77 not out, pal, and I'm putting more time into the farm, so I'll look into things like that."
The WACA mines up to 1000 tonnes of the clay early each year and also makes it available to grade clubs in the State.
Chief executive Christina Matthews said restoring and maintaining the ground's chief characteristic had been vital.
"It's the one feature of the ground that everybody talks about and it almost sometimes doesn't matter outside the arena as long as that pitch has those unique qualities," Ms Matthews said.
"We're confident that will be the case again. England's batsmen can look forward to some nice bounce and pace."
