An investigation by the ABC’s Four Corners has brought attention to allegations against Melbourne gynaecologist Dr Simon Gordon, after multiple former patients claimed they underwent unnecessary or inappropriate procedures under his care.
For decades, Dr Gordon practised in Victoria, specialising in women’s reproductive health. His clinical focus included diagnosing and surgically treating complex gynaecological conditions, particularly endometriosis, a disease that can be painful, difficult to diagnose and deeply disruptive to quality of life.
Now, a number of former patients have alleged that some of the procedures performed were not medically justified.
Several women have claimed they underwent multiple surgeries for suspected severe endometriosis, sometimes over many years. Some allege that subsequent pathology results showed little or no evidence of the disease.
The claims have raised serious questions about clinical judgement, surgical necessity and whether patients were given adequate information to provide fully informed consent.
After the allegations came to light, Dr Gordon has denied any wrongdoing. In 2025, he retired from practice and surrendered his medical registration amid increasing scrutiny.
Since then, former patients have initiated civil proceedings seeking compensation for harm they allege resulted from negligent treatment and inadequate consent processes.

What happens next?
Regulatory reviews are continuing, including processes involving the Australian Health Practitioner Regulation Agency (AHPRA), the national body responsible for overseeing the registration and conduct of health practitioners.
Working alongside AHPRA, the Medical Board of Australia has the authority to investigate complaints, impose conditions on practice, suspend or cancel registration, and refer matters to tribunal hearings where appropriate. Any formal findings will depend on the outcome of ongoing investigations and no findings have been made against Dr Gordon to date.
In addition to regulatory scrutiny and reported police involvement, law firms have indicated they are preparing or considering potential class actions on behalf of former patients.
What is endometriosis?
Endometriosis is a chronic condition in which tissue similar to the lining of the uterus grows outside it, often affecting the ovaries, fallopian tubes and other pelvic structures.
It can cause significant pelvic pain, painful periods, fatigue and fertility challenges, and for many women, it can take years to receive a confirmed diagnosis.
In Australia, around one in seven women is estimated to be diagnosed with endometriosis by their mid-40s. Hospitalisation rates related to the condition have increased in recent years, particularly among younger women.
Treatment varies depending on severity and individual circumstances. Management can include pain relief, hormonal therapies and, in some cases, surgery. Laparoscopic procedures are commonly used both to diagnose and treat endometriosis, and in more severe cases, hysterectomy may be considered.
For many women, navigating treatment options can feel overwhelming, particularly when symptoms are severe and long-standing.
If you have concerns about past or proposed treatment, speaking with your GP or getting a second specialist opinion can help you better understand your options and ensure you feel confident in the care you receive.
