If I google kobo and use the google link to access the site, I arrive at
https://www.kobo.com/ and the Australian flag is displayed in the header bar which indicates I am in the Australian store.
If I click on the flag and reselect Australian store, I arrive at
https://www.kobo.com/au/en
But the next time I come into the store, I am back to the first link above but still with the Australian flag showing.
