Polar Aviation
Polar is a great company to work for (so I hear, from several ex-polar mates).
You will get to fly a heap of hours (mostly max. hours) in fast singles and twins and maybe even some turbine time on their 208 Caravan.
Polar has two bases, one in Newman and the main one in Port Hedland. Accommodation is provided FOC. You earn around 600-700pw before tax.
You need a CIR before applying. Currently though, I am quite sure they are not recruiting as they have just signed a new guy (or so I heard through a mate at King Leos).
Best time to apply would be early next year. In the mean time, I would get some fast single experience - 210, 206 sort of thing.
Try King Leo's or Broome Aviation?
