I dont think you can ever stop the will work for less pay situation. People think getting that first job is to difficult, but is it. I dont know anyone who was persistent that didnt get on somewhere within 18 months (and thats at an award paying job).
To start with why dont we get the moderator to conduct a survey of this forum. This'll give you something to go on when contacting the AFAP or ANU when getting them to enforce the current award or renegotiate it.
Poll this for instance: Is your employer paying you the award wage/salary for your current (piston?) flying position?.
