The towers are not getting Onesky which is an en-route/TCU system. Towers are being fitted with INTAS, a NavCanada system. There are already four INTAS towers. Two more in 2016 and the rest to follow. Onesky only has to provide the data to the INTAS equipment where it is processed for display. The last I knew is that the RAAF had not made decision as to what tower system they will get although they had looked at INTAS a number of times. As le Pingouin says, Airservices and the RAAF will be sharing common equipment and data, not personnel.
