So it looks like Rex is moving from a one Saab RPT ops in Townsville to a two Saab RPT ops in Townsville. N1 & N2 = 1 Saab and Mount Isa to Townsville = 1 Saab, excluding any Pel-Air activity.
From a simplistic viewpoint it looks like Rex is expanding and I think the Northern routes are contracted until March 2013?
