I'd really laugh if they thought Wagga or Albury to the Gold Coast would work, in a 737 Max, when you can't even make an Ejet work direct to Sydney, where 90% of traffic flows. Still no way those jets would be doing enough flying to pay the ROI or financing arrangements without a bread and butter 24/7 main route.
There is also a reason older aircraft generally do FIFO, less capital investment, so the machine can sit idle for most of the day at not much expense. Otherwise your corporate tender bid will include paying for the massive loan on a new aircraft for the whole day, which would blow it out of the water.
