What do you mean by another way?
What problems are you having?
What I meant by this, I get to the step for the payment by credit card and it requires you to fill in your address details and it doesn't give you the option of changing it to Australia. Do I leave it as is? or is there another way I am meant to sign up to it and pay as I am Australian?
I am Australian too
Have you got the Store set to Australia at the bottom of the Join page?
You'll then be signing up from http://www.adobe.com/au/products/creativecloud/buying-guide-education.edu.html
I have set my store as Australia, but the payment details for my credit card still has been set as United States and there are no other options to change it to Australia.
Welcome to Adobe Forum,
I think there is a mismatch of Adobe ID & country which is not allowing to place the order.
Please e-mail me privately the Adobe ID that you are using so that I can investigate it further & assist you.
