If Labor wins the next federal election, it will introduce a policy that involves banning international Web sites.

Under the policy, announced by Opposition Leader Kim Beazley today, international Web sites would be banned by the Australian Communications and Media Authority if they contained graphic sexual or violent material, rated R or higher.

The bans would be maintained by ISPs.

The policy aims to protect the two-thirds of Australian households where no internet filters are in place.

Beazley said it was "too hard" for many parents to install Internet blockers on their computers to prevent offensive material being downloaded.
