This instrument amends Defence Determination 2017/31 to change parts of the rules on overseas education assistance and the published list of benchmark schools. Mechanically, it updates who in the relevant Division is covered and the general education‑assistance provision (see subsections 15.6.8 and 15.6.10.1B) and changes item 36 in Annex 15.6.A. It affects Australian Defence Force members with dependent children overseas by altering eligibility references and the benchmark‑school list used to calculate assistance.
