Operations Coordinators with Qantas Airways work closely with the passengers, cargo, fuel, and flight plans, and the person your interviewer hires for this role needs to at least come to the interview with a basic knowledge of the facets of safety that this job will entail. While you can speak broadly in your answer while covering as much of the job as possible, make sure your interviewer clearly understands your focus on safety by how you talk about the details of the role. As you answer, it is okay to talk about similar safety related measures you've had to take in prior jobs that you've held, and it is okay to ask follow up questions as well.
