John, you're looking at QantasLink as the QF owned & operated section of the business. QantasLink also has an arm of jets operated under contract by Cobham. It's still QantasLink but the jet bases (BNE, CBR, CNS, DRW, HBA & PER) aren't crewed by Qantas employees.
To the best of my knowledge when Cobham advertises for pilots, it's not generally for a specific base, but as needed in any of the bases.
