I seem to recall an ANAO audit of Airservices' Civil/Military Air Traffic System, other wise known in the industry as the One-Sky/Half-Sky/No-Sky Project, which came to light at Senate Estimates and where Airservices were critisised for paying a consultant ridiculous amounts of money in contempt of their own internal contracting procedures.
The Airservices' CEO apologised and said it would not happen again. Since then nothing and the CEO is still in the chair.
By the way he works for the Minister through the DIRD so clearly the Minister and the Department were quite happy with Airservices' performance!
