The option to change the country where your QuickBooks Online (QBO) company's tied is unavailable.
In your situation, what I can suggest is to cancel your current QBO subscription.
See this article for additional information about this process: Cancel your QuickBooks Online subscription.
After you cancel your QBO company, ensure you register to the correct country the next time. If you have questions about your QBO company data after the cancellation, see this article: What happens to my QuickBooks Online data after I cancel?
Post a reply if you have other questions about your QBO company. I'll be around to help you out.
Where is your company located? Do you need to switch from QBO AU version to QBO other region, or else?
