I haven't read it through yet, I just heard from people who have read

In the report is always goes like "web content (http/https)", so I
guess at this point it is really web stuff they care about, VPN are
not being censored.

Exactly, if they have enough trouble with end users switch to
different unencrypted p2p protocol, how are they going to cope with
all the different flavour of encrypted protocol we have these days?
Maybe they'll ban encryption next, "just think of the terrorist!!"

Well terrorist can possibly write a spyware and inflect people's
computer with it that does precisely this to taken down the Australian
internet before they launch an attack. It is indeed proposed to have a
blacklist after all, I don't know how likely will terrorist be able to
get their hands on it, but I think the consequences are very high.
