The Australian government originally stated that the Internet Filter would be an opt out filter for porn, but like the proverbial frog in the boiling water, the Australian government has changed its mind.
"The government has declared it will not let internet users opt out of the proposed national internet filter. The plan was first created as a way to combat child pornography and adult content, but could be extended to include controversial websites on euthanasia or anorexia".
Now, the government is going to block websites it deems unwanted, without actually explaining what unwanted content is.
"AUSTRALIA'S mandatory net filter is being primed to block 10,000 websites as part of a blacklist of unspecified "unwanted content". Some 1300 websites have already been identified by the Australian Communications and Media Authority."
