From the amount of times RFDS come here to pick up patients, usually via another town, they do a lot of work out of Rocky, and then depending on patient, may end up going to Brisbane.
Looking at flightaware, the aircraft in QLD don't seem to have a lot of downtime, and with the way the health system is going in the state, it will only mean an increase in workload for the crews.
One thing to take into consideration is the cost of living, especially rent in places like rocky due to the mines and the increase in prices as businesses cash in on the higher wages earned by the FIFO miners.
Any where on the central coast is going to be expensive, Rocky, Mackay, Gladstone, not sure where all the bases are.
