I just confirmed this is working with iiNet (2nd or 3rd biggest broadband provider in Aus).

The block screen looks like this:

So it is being blocked at ISP level, and it's up to them how they implement the block. For now, they've chosen DNS blocking, which is of course easy to work around.

Here's hoping the block encourages everyday citizens to be take technical measures to evade not just the block but the censorship.
