This list contains 2395 webpages or site variations derived from the those secretly banned by the Australian Communications and Media Authority (ACMA) and used by a government approved censorship software maker in its “ACMA only” censorship mode. The last update to the ACMA list is August 6, 2008.
While Wikileaks is used to exposing secret government censorship in developing countries, we now find Australia acting like a democratic backwater. Apparently without irony, ACMA threatens fines of upto $11,000 a day for linking to sites on its secret, unreviewable, censorship blacklist — a list the government hopes to expand into a giant national censorship machine.
History shows that secret censorship systems, whatever their original intent, are invariably corrupted into anti-democratic behavior.
This week saw Australia joining China and the United Arab Emirates as the only countries censoring Wikileaks. We were not notified by ACMA. …
That’s the problem with secret lists, they become public. And then they can be analysed.
University of Sydney associate professor Bjorn Landfeldt said the leaked list “constitutes a condensed encyclopedia of depravity and potentially very dangerous material”.
He said the leaked list would become “the concerned parent’s worst nightmare” as curious children would inevitably seek it out.
But about half of the sites on the list are not related to child porn and include a slew of online poker sites, YouTube links, regular gay and straight porn sites, Wikipedia entries, euthanasia sites, websites of fringe religions such as satanic sites, fetish sites, Christian sites, the website of a tour operator and even a Queensland dentist. 
ACMA said Australians caught distributing the list or accessing child pornography sites on the list could face criminal charges and up to 10 years in prison.
