The national clean feed Internet scheme, part of the government's A$128 million (US$83.8 million) Plan for Cyber Safety, will impose national content filtering for all Internet connections and will block Web pages detailed in two blacklists operated by the Australian Communications and Media Authority (ACMA).

iPrimus CEO Ravi Bhati said the controversy around the scheme is a "storm in a teacup".

"We are a family-oriented ISP and there has been significant demand from our customers for content filtering. Users can opt-in and opt-out whenever they want, which gives freedom to the customer."

"ISP filtering can work insofar as the technical [theory], provided ISPs allocate systems in the right way and staff and supervisors are capable. The trial is not a big bad issue like it is made out to be; it can't be compared to China because we are not doing anything like that, but are providing an option to customers to choose the content they want to view.

"I don't think [ISPs] should call the shots; the ACMA is investing time and money in research and we will go by them."
