Alister started his medical career as a General Practitioner in South Africa before taking various postings with an international medical assistance company providing primary and emergency care in remote regions. His broad remote international medical experience and background in occupational medicine and public health saw him provide operational and strategic health systems advice to various multinational organisations and government bodies in the Commonwealth of Independent States and Africa.
Alister moved to Cairns in 2013 to pursue a fellowship in public health medicine with a focus on primary health care and health service administration in Far North Queensland. Alister has worked within Queensland Government Health Services, the Aboriginal and Torres Strait Islander Community Control Health Services sector and as part of the executive team at the Northern Queensland Primary Health Network.
Alister is currently undertaking a fellowship in medical administration. He is also the Chair of the Editorial Committee for the second edition of the Chronic Conditions Manual, after being one of two research authors for the first edition. Alister returns to Apunipima after working with the organisation between 2013 and 2017.
