You can do this yourself. Enter a listing for Sharktopus (any listing/country), and click on the "add new edition/country" link under the main specs. Fill in the relevant info in the sheet (remember to change the country to Australia, as the sheet defaults to USA), and click submit.
It will take a while before it goes through the system (Usually does), but when it has, you can add specs if you don't have them at the moment, and upload covers.
