It really does depend on your perspective, as to whether a CEO of ASA is a good one or not.
From the governments point of view, they would like a CEO who maximises profits, and minimizes controversy and bad press, who also sets the company up so they are ripe for privatisation, as that is the end state the government wants.
From a controller point of view, they want a CEO who is interested in protecting and maintaining their employment package, and not in constantly undermining it, and who is more interested in providing a safe service, above and beyond profit driven concerns.
From a pilots point of view, they just want the system to be such that it is as unrestrictive as it can be, while still providing enough structure and retraints to provide a safe environment in which to fly.
The historical problem for controllers has been that the CEO has been driven by the bottom line only, and so has seen ATC salaries as the single biggest drain on profit, and as such has tried to slash this. They have never realised the skill and expertise held by this group of people is the company's greatest single asset, and the one that creates all of the revenue. Without the controllers you have no AirServicesAustralia.
Unfortunately, I agree with Jerricho, and that is while a manager with first hand experience in the field would be ideal, ex-controllers (with only a few exceptions) make very bad managers.
My tip for CEO will be along the lines of Bernie Smith (that is past experience in taking government departments and carving them up into private companies) but more hard line, so as to ensure they can push through with their agenda to sell off all the towers at least.
