QF L/H did have casuals but they were employed through QF not MAM.At that stage if you worked longer than 11 months I think and they had to make you permanent.I remember a number of them going throught the exit interview process.
I don't know if it is true but on another thread there is a post that MAM are recruiting again.If this is the case it is disgusting but consistent with the attitude of the company to cabin crew.
