The first step is to find some data files or online calculators.  Here is 
the US, the USPS has several "zones" to calculate distance, so it provides 
relatively simple CSV tables for integrators.  FedEx has an online form 
that one can use to calculate shipping, and if AU has something similar you 
could build a module that does a POST with all the form data filled out and 
parses the return.  See VENDROOT/lib/Business/FedEx.pm.  (BTW, FedEx seems 
to have changed their form URL because it isn't working for me).  Have fun,
