Globally, the prevalence of EBF among infants under six months has reached 48%, nearing the World Health Assembly's 2025 target of 50%. However, the six-month EBF rate for Indigenous mothers in Australia remains low (18.8%), falling significantly below the national target of 50% set for 2025. There are notable disparities across Australian states and territories, with only the Northern Territory (NT) meeting this target. The NT's success is attributed to substantial state-level investment in healthcare for Indigenous Australians, with the highest per capita spending ($11,082 AUD/person/annum) and the highest proportion of Aboriginal and Torres Strait Islander health practitioners (256 per 100,000 population). Additionally, Aboriginal Community Controlled Health Organisations (ACCHOs) have played a vital role in delivering culturally safe, community-led breastfeeding programs, contributing to higher EBF rates.
