Hey Sal-e,
If thats what you're trying to say then why not say it? Why accuse someone of doing something illegal? If they are I'm sure CASA will be right on to them as they are conducting RPT and also and "new" operation.
I also assume you are a mature professional, so therefore if you know something about their "illegal" methods, you have a duty of care to report them the the authorities......that is.....if you know anything at all!!!
