He and his wife Gwen now live and work at least 6 months of each year in Congo. He is a member of the Royal Australasian College of Surgeons (RACS) International Engagement Committee, and examiner in General Surgery for RACS and the College of Surgeons of East, Central and Southern Africa (COSECSA).

In 2023, AusHEAL, the Australian charity that supports their work in DRC in partnership with HEAL Africa, commenced under Neil and Gwen’s direction, a course to provide practical training and upskilling in Surgery, Obstetrics, Trauma and Anaesthesia Care for Congolese doctors working in rural areas as they are the providers of much of the SOTA Care in the region but often they have received little if any practical training. Importantly, much of the course is taught to Congolese by Congolese specialists in their own language. Results from the course have been encouraging. Both Neil and his wife Gwen were appointed Officers of the Order of Australia (AO) in the 2020 Australia Day Honours for “distinguished service to the international community of the Democratic Republic of Congo through medical support, teaching and training programs.”
