The Labor Party in Australia has proposed installing an internet filtering system to block additional unwanted material, including online gambling.
However, testing by the Australian Communications and Media Authority found that the filters blocked legitimate sites while allowing the passage of sites that fit the blocked patterns, and slowed internet speeds by almost 90 per cent.
Internet provider Telstra said it would not participate in the trial of the system, while smaller companies agreed only to a scaled-down testing.
Further debate has raged over what is inappropriate and what is unwanted and critics fear that the sites found inappropriate by the government will become an ever-expanding list.
