For those who may not be aware there are 2 operators at the 'Rock'. I would suggest calling/emailing both of the companies and touch base with the boys/girls actually doing the time.
Both operations are linked with Melbourne based training schools and of course both training schools would mention the fact that 'some' of the students do get the opportunity to fly punters around at the 'Rock'. I know for a fact that no promises are made. It would be a very short sighted policy to do so.
This is no different to other schools claiming a link or association with other sectors of the industry (mustering springs to mind) in a bid to attract students. As long as no promises are made then they are only stating fact.
