It says pretty clearly in the Important Information section of the QantasLink Pilot Trainee section of the bfound website that "A full breakdown of remuneration and benefits for employees of Sunstate Airlines is detailed in the Sunstate Airlines (Qld) Pty Limited Pilots Enterprise Agreement (as current)." and also "A full breakdown of remuneration and benefits for employees of Eastern Australia Airlines is detailed in the Eastern Australia Airlines Pty Limited Pilots Enterprise Agreement (as current)."
I'm pretty sure that equates to about $51000 base for a 1st year FO on the 100/200/300 for sunnies at least (found a copy online earlier today but can't seem to find the link now).
If anyone finds out what the bonding conditions might be though I'd love to hear it
