Fessio - so that's another big assurance it will be worth listening to. Here are some links from an Australian student conference:

Hey, look at that, you've discovered Melbourne, Australia! Good on you! Well done!
And yes, one of our great treasures is Dr Rowland. George Pell has described her as a leading Australian Theologian. Translation: A real corker!
