There's another reason that doesn't exactly answer everything, but you should consider in the mix of other information: the level of stock availability as a percentage of shares on issue. You'll have to follow your nose, but go to asxonline.com and search for "borrowed". There is a daily report on shares lent and borrowed. One of the columns in the excel sheet that you can download, is the "value of shares committed to lending arrangements" at the end of the previous quarter... you can imagine that short interest is pretty low in stocks that don't have anything committed to lending programs. In the KDR case for example, there is a lot less available to borrow and hence short.
