Internet service provider (ISP) filtering
ISP filtering is a key component of the Australian Government's cybersafety plan. Filtering of online material at the ISP level reflects the view that ISPs should take some responsibility for enabling the blocking of such content on the internet.
This is consistent with the recent child online protection guidelines issued by the International Telecommunications Union. The guidelines state that the strategic objective for the internet industry for child internet safety should be to reduce the availability of, and restrict access to, harmful or illegal content and conduct.
ISP-level content filtering is already occurring in other countries, including Canada, Denmark, Finland, Norway, Sweden and the United Kingdom.
The government wants to ensure a similar level of protection for internet users in Australia.
ISP-level filtering of Refused Classification material
The government has announced that it will introduce legislative amendments to require all ISPs in Australia to use ISP-level filtering to block overseas hosted Refused Classification (RC) material on the Australian Communications and Media Authority (ACMA) RC Content list.
Content defined under the National Classification Scheme as Refused Classification includes child sexual abuse imagery, bestiality, sexual violence, detailed instruction in crime, violence or drug use and/or material that advocates the doing of a terrorist act.
The RC Content list will be based on public complaints to the ACMA and assessed using existing criteria set out in the National Classification Scheme. The ACMA will also liaise with highly-reputable overseas organisations to identify lists of child abuse material suitable for incorporation into the RC Content list, following a detailed assessment by the ACMA of the processes used to compile those lists.
Review of Refused Classification category
The Minister for Broadband, Communications and the Digital Economy recently announced a review of the Refused Classification category under the National Classification Scheme.
The Minister for Home Affairs will conduct the review in cooperation with relevant state and territory ministers. The review will examine the current scope of the existing RC classification, and assess whether it adequately reflects community standards.
As the government's mandatory ISP filtering policy is underpinned by the strength of the classification system, the mandatory filtering legislation will not be introduced until the review is completed.
Transparency and accountability measures
The Minister has announced a comprehensive suite of transparency and accountability measures to accompany the introduction of ISP-level filtering.
This suite of measures is based on the outcomes of recent public consultations on options for transparency and accountability measures relating to the placement of material on a list for filtering.
Agreement to voluntary filtering of child abuse material
While the review of the RC classification proceeds, Australian users would still have access to content that has been classified as RC, including child abuse material which most people would agree is content that should not be available on the internet.
In July 2010, Telstra, Optus and Primus undertook to voluntarily block websites listed as providing child abuse material. Child abuse material is a subset of the RC category of content.
In line with the government's mandatory filtering policy, URLs of child abuse imagery obtained from lists maintained by highly reputable overseas agencies will also be placed on the ACMA list for voluntary filtering, following a detailed assessment by the ACMA of the processes used to compile those lists.
As far as practicable, the agreed suite of transparency and accountability measures for the mandatory filtering policy will also apply to the voluntary blocking of child abuse material.

ISP filtering pilot
As part of its plan to examine the introduction of ISP-level filtering, the government conducted a live ISP filtering pilot in 2009 that provided valuable information on the effectiveness and efficiency of filters installed in 'real world' ISP networks.
The live pilot, managed by independent testing laboratory Enex TestLab, demonstrated that filtering of a defined list of online content can achieve 100 per cent accuracy and no noticeable performance degradation directly attributable to the filter.
Enex TestLab has provided its report of findings from the ISP filtering pilot.
