Not sure why these guys haven't given the TWU a go?
They were great to us in the past and are doing good things for us at the moment at Crapair.....
The best part of the TWU for interested pilots' to call, is the Sydney office on, 02 9912 0700 and ask for someone involved in Aviation.... As long as you guys are prepared to put in some effort, the TWU will react swiftly and professionally for its' members....
All the best
