Note: Figures in this table show Indigenous headcount numbers. Data for this table is reliant on self-identification on the Defence human resources system; therefore, the data is likely to under-report actual participation rates.

1. Figures are for permanent members (Service Categories 7 and 6) and do not include Reserves (Service Categories 5, 4, 3 and 2), Reserves undertaking continuous full-time service (Service Option C) or ADF Gap Year participants (Service Option G).
2. Reserves include all active members (Service Categories 5, 4 and 3) and Reserves undertaking continuous full-time service (Service Option C). This does not include members in Service Category 2, who do not render service.
