Dr Jason Free

Dr Free is a Specialist Weight Loss Surgeon who is committed to improving the lifestyle and health of his patients. His philosophy is to tailor treatment specific to his patients’ goals and health, as well as long-term commitment to his patients’ well-being.

Since completing his surgical training in 2010, Dr Free has focused the majority of his work on weight loss surgery and helping patients with their weight related problems. There is no doubt that weight loss surgery has dramatic effects on a person’s physical health, psychological health, quality of life, confidence & overall well-being.

Dr Free recognizes the enormous long-term benefits of weight loss surgery and is committed to providing extremely safe & effective procedures with a goal to relieve the fears, anxiety & stigmatism of obesity in the community. He does this by being extremely active in the bariatric surgery community, incorporating ongoing life-long learning & teaching amongst his team and trainees.

Dr Free has performed thousands of weight loss procedures over his 15 years of practice, with the overwhelming majority of patients having fantastic results and wishing they had been through his service earlier. He is well respected by his colleagues and has subsequently become a regular contributor to Australian and International scientific community.

Dr Free trained as a surgeon through the Royal Australasian College of Surgeons in Queensland and spent a further 2 fellowship years obtaining bariatric surgery specific subspecialist training in Sydney and Brisbane. Early in his career he pursued further international training, including spending part of his fellowship years learning from world renowned experts at the University Medical Centre of Vienna, and Bariatric Surgery units at the University College Hospital London, and Queen Alexandra Hospital, Portsmouth UK.

Despite being one of the most experienced bariatric surgeons in Australia, he continues to improve his skills and patient care by continuing to spend periods of time with prominent & highly experienced surgeons throughout the world, regularly bringing home a wealth of experience.

Bariatric Surgery in the Public Hospital System

Dr Free has been working regularly at the Gold Coast University Hospital since 2014 as part of the Hepatobiliary/Bariatric Surgical Unit.  He is a very strong advocate for providing bariatric surgery to public patients, who can be extremely unwell due to obesity related comorbidities, and often the most in need for life saving bariatric procedures.

In recent years Dr Free has been working closely and regularly with the Executive team at GCUH to implement a public bariatric surgery program.   It is hoped and anticipated that a more formal public bariatric surgery service will become available in the coming years.  Currently, small numbers of bariatric procedures are performed locally at the public hospital, however usually in exceptional circumstances.  The aim is to provide a formal service to the public offering around 200 weight loss procedures annually in a dedicated bariatric surgery unit.

Dr Free’s current bariatric team including researchers are in the process of publishing & presenting research evidence demonstrating effective results and safety of bariatric surgery procedures being performed by training fellows (under close guidance & supervision of Dr Free) at the Gold Coast University Hospital.


Dr Free’s commitment to the International Bariatric Surgery Community

Dr Free is extremely keen on sharing his knowledge and skills, he has subsequently become a regular invited speaker at Australian & international bariatric meetings including Europe & USA.  Additionally, he is frequently chairperson at bariatric scientific sessions and often involved in panel discussions at bariatric surgical conferences.

Dr Free holds regular clinical immersion programs for bariatric surgeons throughout Australia, whom visit his operating lists to observe & learn procedural skills, specifically including SADI procedure, Robotic Surgical Techniques and Advanced Bariatric Surgery Courses.   He is an accredited experienced Specialist Bariatric Surgical proctor and is required to travel to various parts of Australia to train bariatric surgeons in particular techniques whilst they are learning. He also delivers formal robotic surgical skills training as part of the daVinci Robotic Surgery platform.  Much of his teaching and advice to fellow surgeons includes perioperative methods to improve the patient experience and recovery. 

Dr Free is a strong advocate for teaching & improving the quality of bariatric surgeons in Australia.  He has an ongoing role of overseeing trainee fellow surgeons on their pathway to develop their careers in specialist bariatric surgery.  He regularly volunteers his time at annual trainees’ day learning workshops, and various local bariatric trainee and interest group meetings. He continues ongoing relationships with his trainees, providing an active mentoring role to his previous fellow trainees who regularly seek his opinions & support.  Subsequently Dr Free often travels to assist surgical colleagues who are planning very difficult complicated procedures.

Research and advancement of the scientific literature is important to improve results & outcomes worldwide, and Dr Free and his team including trainees and his Research scientist constantly have several research projects ongoing.  He has been a supervisor for trainees in obtaining their Masters of Surgical Research degrees.  The results of his teams’ research are often presented and national and international surgical conferences.

Dr Free is an advocate for & active contributor to the Monash University Bariatric Surgery Registry.  The primary aim of the Registry is to measure outcomes for patients undergoing bariatric surgery throughout Australia, to ensure quality and safety of procedures and devices.
