Of course the idea of "setting Qantas Free" sounds very attractive, John Singleton probably thought that slogan up.
However there is a second part to the slogan that is not so pretty: "chain down Australian travelers".
If Qantas is "set free" then we immediately need a complete open skies aviation access policy in Australia to "Set Free" Australian travellers from the tyranny of Qantas who own a very large chunk of the aviation infrastructure.
That means allowing international carriers access to all domestic routes as well as the international routes in and out of the country - others can explain this better than me.
