From the dissenting judgment of Justice Callinan in the High Court of Australia in ABC v Lenah Game Meats [2001] HCA 63.

“As populations expand, privacy becomes more elusive.  The right to grant or refuse access to, and to allow to be published, accounts, or records whether by way of film, sound recording, drawings, or otherwise, of what is occurring at a location at a particular time are rights for which very large sums of money can be demanded.  These rights, however they might be described in proprietary terms, can be very valuable indeed.  Some understanding of all of these matters is necessary for any discussion about, and a statement of the law with respect to, freedom of expression, privacy, new forms of property and defamation.”
