The data is very interesting, but as I read it it confirms that even in Australia there is a lot of fresh water coming down each year, and the problem is how to convert it into usable fresh water. Just like with solar irradiation: There is a lot of it coming, but it's very difficult to turn it into usable energy.
PS I've never been to Australia, but I'd like to come someday :)
