I was wondering about that too. By the way, perhaps someone has a rip of that whole interview (I just saw an extract in the facebook story) or know of a functional way to access it from a location that's not in Australia? I tried various VPN's but couldn't manage to get in (might be because I'm a big n00b). From the excerpts it seemed like an interesting interview.
If you have an iPhone I can be of help. I managed it that way, that I changed my location in the app store to Australia, then downloaded the "ABC iview" app. Once you've did that, type in "The Mix" in the search bar and then when you have downloaded it you'll find the interview in the episode of the 31 of August.
After downloading the app you can change your location back to wherever you are while keeping the app without any further issues.
Hope I could be of help!
