According to the latest info, ASA will have a VHF repeater at BNA (already installed) operated from a consol in BNE and that operator will provide a service similar to the old AFIZ that is mentioned in the post by Geoff above. In addition the operator will have surveillance capability (Radar/SSR/ADSB) within the limits of the coverage there.. It will in fact be a sub-FIA based on the proposed area in the draft AIP SUP. The controller will have co-ord ability with other sectors etc. The CA/GRS will go. Cross reference to the CASA proposal on changing the frequency of Lismore/Casino CTAFs is in conflict with the ASA proposal. I guess CASA will review after their consultation closes on 11 July.
I think CASA have a problem with AFIS as it is a "service" and does not refer to an "area". What is proposed is a service provided within a defined area which may or may not have an ICAO definition(??). A class D zone would do the job, but nobody wants to pay for it.
