Good question AS.
I just got that letter too and was really surprised seeing the one exactly a year before was about the up front rates going up by over 20%.
Muppity can I ask has SIVF Canberra clinic got the private health insurance cover now so the day treatment procedures can be billed direct to your PHI? A year ago when the new facility was build, the day procedures had to be paid up front ($1000+/$500+ for EPU and ET respectively) with little or no PHI coverage, as they hadn't been approved by any of the PHI at that time (which they didn't tell anyone about before the procedures).
BTW the letter does mention the cost will go up in November with the new Medicare rates announced then. The cynic in me wonders how much more they will aim to charge now with this new system...
