Australia now has an Internet filter.
Moreover, it’s one which gives the courts the right to determine the method of and scope of a block, and deny anyone other than an ISP the right or ability to challenge this.
The net effect of this: if the court orders a block based on, say, IP address, then any innocent websites that happen to be collocated with the target become collateral damage; a fact that these impacted websites have no recourse to. Only an ISP can do so.
We’ve been here before, and apparently learned nothing from it.
Remember this when it comes time to vote again. Remember, too, that both the Labor opposition and Coalition government waved it through in this form.
