Consultations continue with a number of other ISPs that have applied to take part in the trials, Conroy said. Shadow minister, Nick Minchin, said: "it is extremely puzzling why two of the nation's three largest ISPs, Optus and iiNet, have not been included in the first phase of these trials, despite expressing a willingness to participate...[and] Australia's largest ISP
Telstra BigPond has refused to participate. Without the 'big three'. IT is difficult to see how these trials could be in any way credible."
Conroy said that testing with each ISP would take place for a minimum six weeks once filtering equipment had been obtained and installed.
"It will look at the efficiency and effectiveness of a range of technical solutions, as well as other issues such as the ease of circumvention, impact on internet speeds and user experience."
ISPs were invited to put forward proposals to participate in two pilot streams: filtering the ACMA blacklist of prohibited URLs and filtering the ACMA blacklist of prohibited URLs, as well as additional content filtering solutions that may be offered as optional services by ISPs.
Minchin called on the minister to commit to the independent auditing of any results, adding: "the minister also needs to explain what his measures of success will be for these trials and outline how they will be conducted and what filtering technologies will be utilised."
