Telstra and Optus will impose a filter on child pornography and abuse websites for all internet subscribers from halfway through 2011. Primus Telecom, however, remains non-committal to its implementation. The filter will apply to the 450 child abuse websites identified by the Classification Board…The three service providers were identified by communications minister, Senator Stephen Conroy, as “voluntarily” implementing the child porn filter ahead of a review of the refused classification category by the Classification Board. However, under both Telstra’s and Optus’ plans, users won’t get a say as to whether the filter will be applied to them, nor will there be an opt-in or opt-out exclusion to it, according to spokespeople for the telcos…however, the filter will only block offending material travelling over standard web protocols such as HTTP. Other traffic from FTP sites, email as well as peer-to-peer networks such as BitTorrent will not be stopped.
