Hello Kelly-ferguson-s,
Welcome to the Community page,
Yes this is possible you can have as many accounts as you like. It's just a case of purchasing the product version for that region. If you have a look at this link , click on Asia Pacific > then select Australia, then you'll be able to purchase it to use. Here is also a link for the Australia pricing as well where you can purchase the account type you need as well. You can use either link.
