While the content filter scheme is offered free to customers, some ISPs have not ruled out charging for the service once the trial ends.
“Post June, we will definitely offer it as an optional service to our clients,” Robson said. “For a one off account, we will probably charge $50 per annum.”
Highway 1 also expressed interest in converting the filter into a commercial service.
“The appliance we are using is commercially extendable,” Powell said. “But we will wait for results from the Government before making a decision.”
The national clean feed Internet scheme is part of the Government's $128 million Plan for Cyber Safety. It will impose national content filtering for all Internet connections and will block Web pages detailed in a blacklist operated by the Australian Communications and Media Authority (ACMA).
Supporters of the trial have called for critics to wait and see the results of the trial before dismissing it and claimed it could help in the fight against child pornography.
However, emotions have run high since the ACMA blacklist was reportedly leaked on the Wikileaks website in March.
Under a Federal Government contract, Enex Testlab, was commissioned to execute and monitor the trial but can not disclose any related internet filter pilot results. The trial is set to end by June 30.
The eighth ISP participant, Optus, was unavailable for comment at the time of publication.
