66biscuits you need to do some homework. Granites will definitely not be taking the A320.
I believe the aircraft will initially service the Cloud Break contract for FMG as well as supplementing additional capacity to Karratha, where the CP contract is going to need it. Add some new routes to the East Coast from Karratha and perhaps an international link as well.
excerpt from latest Skywest newsletter :
Skywest's first A320 Aircraft arriving soon…
We're looking to grow and expand and part of these plans, we're pleased to announce the imminent arrival of the first Airbus A320 aircraft into the Skywest fleet. This "big sister" to our existing aircraft will become the newest and largest type that we operate. Initially earmarked to serve the needs of our mining charter clients we hope to use it on existing and new regular passenger routes in the coming year. The first A320 has just been painted in Skywest livery and should come online in early July. So, keep your eyes peeled the next time you're boarding a flight at Perth for a glimpse of the Skywest future.
