WA Premier Mark McGowan has labelled strawberry vandals “dropkicks” as his Government announced a $100,000 reward for their capture.

Speaking at IGA Leederville this afternoon, he said “every West Australian will want the book thrown at them”.

He said the Fraud Squad was investigating and anyone caught could be subject to a 20-year jail term.

“They deserve to go to jail,” he said.

He said “our strawberry growers are going through a tough time”.

“I’d encourage all West Australians to continue to buy West Australian strawberries,” he said.

“It’s the peak of the market, they’re delicious…you can take a simple precaution (cut them up); they’re totally and absolutely safe.”

WA’s strawberry industry provides about $88 million a year into the State’s economy.
