The device is called the Shadows Ankle Stabilizer. It is small and light and could easily be sent to Australia. I don’t know what shipping would be or how long it would take, but I could look into it for you. Look at the following page for sizing information http://www.fastrehab.com/products-page/ and let me know what size you would need. The cost of freight won’t change much if you got a pair because they only weigh 4-6 ounces. If you can swing it, I would get a pair.
