You must offer "free" shipping to Australia by incorporating the cost into your retail price. We do, however, allow sellers with large/bulky/heavy items (such as furniture) to charge shipping. You can also offer additional options eg) express post, courier and/or other delivery zones, and charge accordingly.
The price of a product (inclusive of shipping) must be the same or less than the total price of the same product on other sites (such as on your own website) if shipping is charged separately. We understand that you cannot control pricing on third-party sites that buy your products wholesale.
