Notably today's media release had 7 paragraphs and managed to mention Qantas 3 times, twice using the "Qantas predatory" phrase (perhaps they should trademark it).
The only logical thing here is for Qantas to claim Rex is being "predatory" by launching on a route they have a monopoly on. All that being said my moneys on Qantas for this one. They have a Qantas Club in Devonport and a strong 3-4 flight per day schedule already in operation.
