The Australian Catholic Bishops Conference delegate for media issues, Bishop Peter Ingham, said other countries were miles ahead of Australia when it came to keeping the internet as safe as possible for children.

Comparable western countries, such as the UK, Canada, Sweden, Norway, Denmark and Finland already have ISP filtering in operation, Bishop Ingham claimed.

In many of these countries, the ISPs themselves have initiated the filtering in order to live up to the community's expectations that illegal material or material that is harmful to children should not be available on the Internet.

It is disappointing to read reports that Australia's largest Internet provider, Telstra has said it will not participate in trials of the federal government's national internet filter.

Bishop Ingham said the ACBC held the position that whatever could reasonably be done to filter out illegal sites at ISP level, should be done: Arguments that civil liberties will be infringed by internet filtering are absolutely spurious, as the government's proposal simply aims to ensure that the material accessible on the internet is in line with the restrictions already in place in regard to DVDs or publications.

Pornography of any kind is harmful to human dignity and often degrading to women. Research shows that internet pornography is also becoming more and more harmful to marriages and relationships. In particular, every parent knows that much of the pornographic material that can be found on the internet ought not to be accessible to children.

We call on the community to get behind the federal government on this important issue and support its attempts to keep pace with the rest of the world when it comes to cleaning up the Net in a fair and reasonable way.

The Australian Christian Lobby has accused the Federal Government of breaking its election promise to censor the internet after the policy was softened in the face of relentless criticism.

The lobby's managing director, Jim Wallace, wants the Government to introduce legislation forcing internet providers to block hardcore porn (X18+) on a mandatory basis, in addition to illegal content. Australians would then have to opt in to receive legal softcore (R18+) adult material.

Communications Minister Stephen Conroy has long said his policy would introduce compulsory ISP-level filters of the Australian Communications and Media Authority's blacklist of prohibited websites.

But he has since backtracked, saying the mandatory filters would only block content that has been refused classification (RC) - a subset of the ACMA blacklist - amid widespread concerns that ACMA's list contains a slew of R18+ and X18+ sites, such as regular gay and straight pornography and other legal content.

"That doesn't meet the election promise as far as we're concerned at all," Wallace said in a phone interview: The promise was clearly about providing a safer internet environment for children and to do that you need to mandatorily block in the first instance pornography and R18+, and then provide an opt-in system for those adults who want to access it.
