An Aerodrome Reporting Officer (ARO) is a nominated position approved by CASA. It basically just the person responsible for providing CASA/AsA with the up to date status of the Airport. Outside of those functions, you do what ever else your employer wants you to do, if anything. The ARO can be the refueller, the local Flying instructor etc. It depends on the size of the airport. It's a lot different to the Safety Officer/Operations Officer on an major airport. The ARO functions are just a small part of their job.
