...18 groundstations which will provide significant enhancements to the Launceston "temporary" radar.
Erm, I understand there will be 8 groundstations, an aircraft has to be within range of 3 to provide a return. The three have to be close together for ground monitoring, far apart for enroot. Once commisioned I don't think they'll need the present radar, and it may go before then anyhow.
Didn't mean to pick on your service Scurvy. I only wrote it like that coz the minister had just announced a new interest in NAS (it has taken him til now to read all the posts???). As your ceiling has been lowered to A085 by that silly process with no benefit anticipated or revealed it is likely it will continue to drop with the same result.
