The GP who tried to murder a pharmacist after she reported him to AHPRA has been barred for 25 years – the longest practice ban ever imposed on a doctor in Australia.

Dr Brian Holder, 71, is currently serving a minimum 10-year sentence for attempted murder after attacking Kelly Akehurst with a 15cm fishing knife hidden in a bunch of carnations.

The GP had plotted his revenge after learning the pharmacist had lodged a complaint about benzodiazepine scripts he had written for eight Indigenous women.

He hired a private investigator to track her down. After posting a suicide note to his wife, he walked into the Terry White pharmacy in Port Lincoln, SA, handed Ms Akehurst flowers, saying “These are for you”, before attacking her with the knife.
