I was in Australia backpacking from Feb 2011 to Jan 2012 and managed to read the complete works of Stephen King! I had already read about 20 books before I went and read the rest, including the Dark Tower series, in Australia as his books were easy to get from second hand book stores (plus I really like his stuff). Under The Dome is a good one too.
Did you get to Fremantle? That's my hometown. Hope you had a great time over here. Though how could you NOT, travelling Oz and reading King...
I did go to 'Freo' and loved it! Such a cool little place which seems to be home to so many classic American cars everywhere like Ford Thunderbirds etc , I much preferred it to Perth.
