ADF Interview Practice 2025 – Complete Prep Guide

The Vice Chief of the Defence Force (V-CDF) is a key leadership position within the Australian Defence Force, responsible for assisting the Chief of Defence Force in overseeing military operations and administration. Vice Admiral David Johnston has held prominent positions leading and managing various Defence initiatives, and his role as V-CDF includes responsibilities such as coordinating the activities of the three services and contributing to strategic decision-making.

The other options include individuals who have important roles within the Australian Defence context. For example, Richard Marles serves as the current Deputy Prime Minister and Minister for Defence, reflecting the government's civil oversight of Defence matters but not directly in a military role like the V-CDF. Angus Campbell serves as the Chief of Defence Force, leading the ADF, while Vice Admiral Mark Hammond has served in other capacities but not as V-CDF. This distinction highlights the specific role and position associated with Vice Admiral David Johnston.
