That is infinitely cheaper than the obscene land rents at Brisbane Airport!
Cheaper for who?? Sure it's cheaper for the owner of the simulator. The end users meanwhile get screwed forever. Seen this in aviation on so many levels so many time. Someone in the office makes a decision that's cheap for them that introduces ongoing costs that everyone else pays for them and in some cases makes the business more inefficient. 'Oh but it was cheap' is always the justification.
