I am M.A.M Perth, not sure about Mel but think it would be similar. Firstly progression to full time...forget it, dont think it will ever happen. We work 100-120 hrs per month,20days flying.Pay is $27 something per hour plus close to $5 per hour D.T.A. Money not bad as I dont think I work that hard. With the current roster system you could end up anywhere the A330 and 767 go to. Could do up to a 6day trip[ although I have never had one]. Crew are great and I dont notice any difference in the way they treat me being M.A.M .However treatment from Qantas is very different. Dont think they have much regard for casuals.
Have heard that lots of casuals are resigning in MEL and SYD, not sure why. Hope this helps in some way...
