The 74-year-old man is set to appear in court on almost 100 counts of rape after police alleged he assaulted women aged from their late teens to their 40s between the early 2000s to 2015.
The man committed the offences during his role as a doctor at a private health centre at Tarragindi in Brisbane's south, police said.
The former medic was charged on Tuesday with 148 offences including 94 counts of rape and 54 counts of sexual assault.
An extensive investigation was launched into the alleged historic sexual assaults after detectives established Operation Xray Cariyna, police said.
"Crimes of this nature are a deplorable violation of trust, and investigators are committed to pursuing every avenue to seek justice for the victim-survivors," Detective Senior Sergeant Denis Silk said in a statement.
"If anyone has further information or experienced similar interactions, we encourage you to come forward directly to us or anonymously to Crimestoppers.
"I want to reassure victim-survivors that you are not alone, support services are available to you."
The man is expected to appear in Brisbane Magistrates Court on June 23.
