Australia's biggest technology companies, communications academics and many lobby groups have delivered a withering critique of the government's plans to censor the internet.

The government today published most of the 174 submissions it received relating to improving the transparency and accountability measures of its internet filtering policy.

Legislation to force ISPs to implement the policy is expected to be introduced within weeks. The filters will block a blacklist of "refused classification" websites for all Australians on a mandatory basis.

Most of the submissions called for full transparency surrounding the operation of the list and for all sites placed on the list by bureaucrats at the Australian Communications and Media Authority first to be examined by the Classification Board.

They supported a regular review of the list by an independent expert and the ability for blacklisted sites to appeal.
