Emerald Qld was predicting profits and did invest in a separate terminal for charter (without security) and upgraded security at the RPT terminal, including paid parking. A good amount of that was financed by Government grants. Now 5,000 mining jobs have gone in 2 years from the mines it serves and more from the town that served them.
Currently the fees stand at -$20.60 per passenger embarking or disembarking, passenger screening $15.96, landing fees RPT (not disclosed), others $11.50 per tonne. Parking $10 per day, annual fee $3,000, hire companies $2,900 per parking spot. Working on one passenger getting off and one on, both with a car in the park (pick up / set down or left there for the day) on an RPT that is $35.96 for the seat. Multiply that by the capacity and add landing fees to work out the max return per RPT. Similar costs per charter aircraft, except we know landing fees.
Qantas & Jetstar have flights. Q has up to 7 flights a day, Dash 8s. Working on 50 seats max that's $1,798 + landing fees per flight. Weekends are quiet, but you can get the idea. Wagners can charge what the market will bear. At these rates Emerald is thriving and just finishing another paid car park facility. Council is trying to stop people parking in the nearby retail and industrial sector roads. Depends on the investment to determine if the return is suitable.
