Airservices may make some savings with a new system but it will have nothing to do with Airservices and Defence having the same system. Defence will operate the same way and access through their airspace will be the same as it is now.
If someone says there will be $300M of savings by integrating Defence and Airservices to the same system show us where and be accountable for delivery. I thought not.
Airservices will make savings, which they could do now but a new system is a nice trigger, however it will have nothing to do with Defence.
Watch the rabbit because this will be a magic show with rubbery figures.
