I think the way of tackling this is for as many people as can be mustered to write individually to the Australian Information Commissioner complaining that CASA is breaching their privacy by publishing their personal information to the world.
CASA argues it is required to do this by a Regulation it wrote to make life easy for itself. The Act requires it to keep a Register but it is only the Regulation that “requires” it to be published on the internet.
In my view, the Regulation is over-ridden by the Privacy Act and, in any case, is probably beyond power because the only head is that of “safety”.
Hard to make a safety case when none of our motor vehicle registrations is publicly available and those responsible for aviation safety could have access similar to police with vehicle regos. Even harder when RA aircraft fly around without the owner being publicly identified.
