Hi Karen
It cost us around $5500 before we got some medicare rebate of around $1800, but that was the big first payment to cover matching you with the donor, all the tests and things like that. Also, once you reach the threshold, you get a lot more back, so if you do need more than one cycle, each one should cost you less as you don't have to pay the 'admin' costs of setting up as a new client and because you get more back from medicare.
Not cheap though!
