Try doing some back-of-the-envelope calculations yourself. Here are mine:
$10K per hour operating costs for the "average" FIFO aircraft;
5 hours average round trip time;
1 round trip per day, 310 days per year;
16 flights out of YPPH in the morning and 16 in the afternoon, gives:
(16 + 16) x 310 x 5 x $10K = $496 million.
Okay, If I use your figures here is what I get
32 Flights a day (16 in the morning, 16 in the evening)
x $10,000 an hour [what the hell are they chartering?] = $320,000 per day.
Hence 'if' the operation was a 5day operation you would see approx 9,920 flights a year for FIFO
Taking on average of 9,920 x $10,000 per hour I get = $99.2million
