Earlier this month, Patterson, 50, was sentenced to life, with no chance of release for at least 33 years, for the murder of her in-laws Don and Gail Patterson and Gail’s sister Heather Wilkinson.

She was also found guilty of trying to kill Heather’s husband Ian Wilkinson by serving them a toxic mushroom lunch at her home.

Dr Webster treated the Wilkinsons at a tiny hospital in Leongatha, before their mushroom poisoning was identified and they were urgently transferred to a major Melbourne facility.

He also saw Patterson – who claimed to have gastro-like symptoms – at the hospital, and says he knew she was guilty almost immediately.

“I knew,” he had earlier told the BBC.

“I thought, ‘Okay, yep, you did it, you heinous individual. You’ve poisoned them all’.”

An audio recording of his call to police about her decision to discharge herself from hospital against medical advice was played at the trial.

The Aphra investigation concluded that Dr Webster must do at least eight hours of training in topics including professionalism and ethics, professional communication, privacy and confidentiality, and social media.

He must also be mentored by another doctor for five hours a month for a period of one year, Dr Webster says. He called it an “onerous condition”, which might require him to take one day off each week to travel to Melbourne, and could mean he has less time with patients.

“Ultimately, the community is getting punished as well, and that’s disappointing,” he said.

“There’s never been any question about my competency and skills as a doctor. It’s all about my attitude and presentation, and maybe in this modern world, that kind of thinking might be a bit archaic. Doctors are human beings.”

He added that he has the “full support” of the local community: “I’m not going anywhere. I just have to go back to school.”
