Hi Jeana,The cost of BEC-116BT is 422.333AUD. The average cost to ship to Australia through USPS is roughly about 385.583AUD. Now, if you were to install using our ez-retrofit box installation method, then you would certainly have a minimum expense to remove the toilet at some future date (assuming that by that time they aren't yet as popular as we expect them to one day become, and it’s true health advantages are not yet as widely and well understood as they will one day become). Hope this helps.
Sincerely,
Amy Chung
