Who is the Deputy Chief of the Air Force?

• A. Air Vice-marshal Stephen Meredith
• B. Air Marshal Richard Brown
• C. Group Captain Susan Lee
• D. Wing Commander Alex Chen

Answer: (A)

The Deputy Chief of the Air Force is the second‑in‑command of the RAAF, a senior leadership role that supports the Chief of the Air Force in running the service, including policy, operations, and resource decisions. The option named Air Vice‑Marshal Stephen Meredith fits the typical profile for this appointment—an Air Vice‑Marshal is a three‑star senior officer who would be expected to occupy such a high‑level role. That makes this choice the best fit.

The other options show individuals of different ranks or names not associated with the Deputy Chief position, so they do not align with the role's level of seniority and current assignment. As leadership appointments can change over time, it’s worth verifying with up‑to‑date sources if needed.
