I'm currently halfway through this book at the moment and it's great. Australia has an amazing (mostly free) resource called
TROVE a digitized archive of newspapers and periodicals dating back two centuries where the bulk of of the historic reports came from.
There's quite a number of reports both historical and current around the area that I live ad I believe that I know the young woman who had the 2012 sighting in the town of Wingello, NSW.
A great podcast (as always) and a great book if you have even a scant interest in the Yowie.
