Inflamed by her passion for animals and enraged by WA's shark cull policy, Drew Gregory googled the website of Premier Colin Barnett last December and penned him an email message:
"Give us a call, you c…, I'm going to f…ing kill you, Colin," it began.
"Knife to your throat. Expect it coming, you are a waste of f…ing human space. You're a murderer, you are evil, I will kill you."
A day later, police raided the 18-year-old's home where she lived with her parents in Beaconsfield and charged her with making a threat to kill.
In Perth's District Court yesterday, Gregory was told by a judge that her foul-mouthed message was a product of immaturity, anger and stupidity.
Gregory admitted the charge and was sentenced to 36 hours community service and a nine-month supervision order.
She was also given a spent conviction.
"The threat had to be taken seriously, and it was," prosecutor Laura Christian said.
"It had a significant impact on Colin Barnett, his family, his staff - and also caused significant expenditure in additional security."
Judge Henry Wisbey said Gregory had shown deep remorse over the message, including during a face-to-face meeting with the Premier months after threatening to kill him.
Gregory's request for a mediation meeting with Mr Barnett was granted and the court was told the Premier explained to her in detail the impact the crude threat had had.
"The Premier, whilst emphasising the seriousness of what had occurred, was generous in his understanding of your predicament and the reasons behind it," Justice Wisbey said.
Defence lawyer Alan Camp said Gregory's actions were an "emotional response to an emotional issue" and she made immediate admissions to police.
"I get really angry, so I just did it and it made me feel better," she said in a police interview.
"What I did was shameful - I am devastated by it."
Gregory now intends to study zoology, the court was told.
Following the hearing, Mr Barnett said he was pleased with the outcome.
"I met with her, she apologised and I accepted that apology," he said.
"It was a serious matter but I was pleased to see that she did not get a custodial sentence.
"I hope she can now move on from this."
