Hello @user072319 ,
In this case, submitting a sitemap for com.au won’t help as specified Shopify store’s URLs would still be .com anyway, and even if had com.au URLs they are non-canonical(duplicate pages), and not the primary domain.
You have to set .com.au as the primary domain so that all the URLs in the sitemap will then point to .com.au, and .com.au will become the primary domain.
Hope this helps,
Gina
