How do I change my billing currency/country?

I've want to change to AUD for billing, and this was the response I got from raising a ticket:

Thank you for contacting Dropbox support! As I understand it, you would like to switch the currency used to pay for your Dropbox Pro account.

Changing the currency used to pay for an account is something we cannot currently allow for renewals.

However, if you would prefer to subscribe from a different billing country, you will first have to cancel your current Pro subscription at the following page:

Please note that no files would be deleted, although synchronization would pause for the time being before you upgrade again.

On your next scheduled renewal date, your account will be downgraded to our Basic plan, at which point you can upgrade again with the updated country at the following page:

That's correct, Anthony. There's no way to change the billing country on an active subscription. You need to let your subscription lapse and then sign up again with your new payment method. The following is a reply to a similar question from a Dropboxer:

Hi there! Unfortunately, it's not possible to change your billing country. If you'd like to change your billing country, you will need to allow your subscription to lapse, and then sign up for a new Pro subscription with your new billing information. I apologise for the inconvenience!
