Check the DOTARS website, I am afraid you have just missed out on getting one into Australia under the now defuct 15 year old rule.
While you are checking the Dotars website, have a look and see if anyone has RAWS for the JZA-70, as that will now be your only avenue of getting one fron Japan. That being said, there are a few JZA-70's 4 sale at the moment, including one on these forums.
