Along with his wife Belinda, Gary has also opened the 'Nutrition for Life – Diabetes and Health Research Centre' based in Launceston which provides nutritional care around Tasmania and Australia. Gary has a longstanding interest in the preventative aspects of health outcomes, particularly before operating on his patients. Recently an AHPRA (Australian Health Practitioner Regulation Agency) investigation into Gary’s qualifications to give nutritional advice has concluded. This investigation (which lasted for more than two years) has resulted in Gary being issued a ‘caution’. The Medical Board of Tasmania, under the umbrella of the Australian Health Practitioners Regulatory Authority, have advised him; ”In particular, that he does not provide specific advice or recommendations on the subject of nutrition and how it relates to the management of diabetes or the treatment and/or prevention of cancer.”
