I would have imagined that someone from QLD would know better.[1] The abuses of the 1970's in QLD are surreal, but they are only a few short decades away; that's to say nothing of One Nation. But, to pause the banana-bashing for a moment, there are also regular abuses of the police databases in other states.

And all this for what supposed gain? I can't see the exact benefit this will bring as opposed to keeping things as they are. And it always starts off with a voluntary anonymous option, then all you need is one murder/kidnap/rape vaguely connected to the anonymous option in some way and that will be removed in a shower of tabloid hysteria.
