Fieldmouse,
Airport privatization was a Labor initiative, the Lib/NAT government agreed, and followed through.
Neither colour of Government has enforced the intent of the Airport Act 1996, and associated legislation, but have let developers loose --- disastrously.
As a matter of interest, the FAC airports (with the exception of Camden) were all profitable, before they were loaded up with debt by new owners.
Tootle pip!!
