He maintains a strong interest in the minimally-invasive management of complex groin and abdominal wall hernias including large incisional hernias, benign and malignant upper gastrointestinal tract illnesses including the management of gastro-oesophageal reflux (“heartburn”) disease, gastric and oesophageal cancer as well as all cancers and ailments of the liver and pancreas. Additionally, he was trained for two years from 2018-2020 as a Clinical Fellow under the country’s leading bariatric surgeons in Australia’s only Bariatric Centre of Excellence at St George Hospital allowing him to provide the highest-quality management of patients suffering from obesity.

Dr Fisher is a champion of endoscopy, minimally-invasive as well as robotic surgery as this allows him to always perform procedures as efficiently as possible, whilst ensuring as little impact on patients’ recovery pathways as possible.

Oliver believes that compassionately and attentively listening to what is said is the key to understanding each patient’s individual problem and the foundation for a trustworthy, honest and open relationship allowing for the best outcomes to be achieved. He firmly believes that providing care to his patients is the ultimate privilege, and attempts to let this belief underpin and transpire during all interactions with his patients.
