Having a third party provider maintain the sims and run the building isn't new or uncommon, CAE does it for
quite a few airlines.
QF previously and currently have farmed out endorsement training to 3rd party providers, both overseas and in Australia, to provide endorsement training when sim capacity at their own centre has been full. Trainees complete a generic course at the 3rd party centre then a few follow up sims in house to align with QF procedures.
