"The loophole with the 6 month restriction for any employer is that if it is casual, it does not apply."
Incorrect info here - it is both the employer and employee to know the rules of engagement (employment). Under no circumstance can a WHV holder work more than 6 months for the same employer, not even can a waiver be issued for this.
Still seems a one of event. Not to mention a fresh CPL on a temp visa getting a start so fast, I know guys wait years (missing a few facts I think).
My friends go to places like Hawaii for flying lessons at a much cheaper rate than here in AU.
