Welcome to the forum. :flower:
Google is your friend. Use the site to search for the item along with Australia. No one here is going to be able to tell you out of thousands of vendors who would ship that specific item to Australia. You really should look for an alternative product, because a flash drive is not worth the hassle. There has to be someone in Australia selling it, planning to sell it in the near future, or that has a similar or alternative product.
