I'll put in a vote for this. It would be great if they connected with all Amazon marketplaces 🤘
We cannot speak on behalf of Shopify, but as far as we are aware, they don’t have any plans to add extra marketplaces. However, there is an app that is available right now that can help you connect not only to Amazon Australia, but to all Amazon marketplaces. This can be done with the help of Codisto LINQ. This is an app available on the Shopify app store (https://apps.shopify.com/codisto-linq).
