A Golden Bay woman has been charged after an investigation into public sector corruption at the East Metropolitan Health Service.
Financial Crimes Squad detectives executed a search warrant at the woman's Golden Bay residence on June 25.
The 68-year-old is accused of using confidential information to secure procurement contracts for goods used by her employer - the East Metropolitan Health Service.
It will be alleged the woman, who was employed in a clerical role, set up a private business for the purposes of securing the business arrangement.
It will be further alleged she used a false identity when communicating with East Metropolitan Health Service in relation to the supply of goods.
At no time did the employee identify herself as being involved with the private business, or declare a conflict of interest with her employer.
Between 2016 and 2019, the employee's private business secured 203 orders for goods valued at $123,759.
All the goods were legitimately required by East Metropolitan Health Service and all the ordered items were delivered.
Financial Crimes Squad's Detective Senior Sergeant Ken Foster said the allegations highlighted the well-planned structure and processes the employee put in place to conceal her involvement from her employer.
"These offences represent a breach of public trust and an abuse of a public position for personal financial gain," he said.
"The alleged offences are not just about the conflict of interest of a public officer, but the unlawful use of confidential information and the impact such conduct has on other, legitimate, businesses who are competing for government contracts and who ultimately miss out on work they may have otherwise secured."
The woman has been charged with being a public officer who unlawfully acts on knowledge or information obtained by their office.
She is due to appear in the Perth Magistrates Court on July 24.
