That supposes that QQ actually want to touch RPT, which I can imagine they wouldn't want to do unless somebody was handling the distribution or underwriting it. Their biggest opportunity would be to pick up the VARA business (or even just the contracts) and focus on those. Those Fokkers won't hold up well doing regular runs up and down the coast with multiple sectors, short turns etc. Plus, there is the small issue of Qantas holding the largest stake in QQ at the moment - subject to the ACCC investigation.
Who said anything about RPT ? QQ could just do unlimited charters.
If they let JAT, Air Med in during pilots dispute, any OZ carrier would surely be allowed unlimited charter flights. Not up to CASA, up to transport minister, who would have tourism operators screaming at him for flights & therefore employment.
Of course QQ would need back up aircraft, but dont' they have 30 ish F70/F100s ? Add 14 of VARAs & you have nearly 50. Assuming 15-20 could be freed up, that's a decent fleet.
