Hello aussie22 -
You will likely wish to select Australia as your listing site in the upper right of the listing creation page. Then, you shouldn't need to make any selections in the Shipping Tools area of the page, as once you have selected Australia as your listing site, that is the default location for your shipping.
If you do not select any international shipping services or other area's to ship to, none will be available in your listings once they are live on eBay.
