Move my subscription from Singapore to Australia

Hello,

Unfortunately, Microsoft does not allow you to transfer an existing Microsoft 365 Family subscription from one country to another.

Normally, you would need to turn off recurring billing on your Singapore subscription, let it expire, update your profile's country and payment method/billing address, and then purchase a new annual subscription from the Australian Microsoft Store. This is Microsoft's official guidance: https://support.microsoft.com/en-us/accounts-billing/change-your-country-or-region-in-microsoft-store

You can check your current subscription here: https://account.microsoft.com/services

You can continue using the same Microsoft account, so you won't lose your existing OneDrive files or Office documents.

However, there is one thing I want to point out. Microsoft recently changed the storage benefits for new Family subscriptions. Depending on when you purchased your current plan, you may have 1 TB per person, whereas the newer plan may use a shared storage pool. So I would suggest checking this before making the switch, especially if your family uses a lot of OneDrive storage.
