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. Some figures have been adjusted from what was reported in the Defence Annual Report 2018–19 to account for retrospective transactions.

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.
