As an Aussie as well, I think not knowing about something is often aligned with people also just not caring. This goes for most things technology really, most people don't care until it impacts them.

We all have only a finite amount of things we can care about in a day and for many Aussies, laws, especially laws around the use of technology aren't front of mind for the average Australian. But as time goes on and these laws actually start to impact us, then you will see people caring.
