Why WA is a category of its own
Western Australia carries the highest concentration of rotational workforce aviation in Australia. Iron ore, gold, lithium, nickel, gas and a continuous pipeline of infrastructure work all draw crews from a single dominant origin into aerodromes spread across an enormous area, and much of that demand lands on the same early-morning departure windows.
The practical result is that WA charter is planned around three variables: departure timing out of Perth, aerodrome capability at the site, and how much surge the project generates. Get those right and the program is efficient; get them wrong and you are paying for accommodation, lost shifts or aircraft that cannot use your strip.
