To my fans in Australia
Please forgive me. I really did hope and expect to come to Australia during the Confessions Tour and asked my managers to try to include some shows there. I have fond memories from previous tours. Unfortunately, the logistics just didn’t work out this time around. We looked into going from Japan to Australia and ending the show there but I have to get my kids back into school in England and they are, as you can understand, my most important priority. The important thing to remember is that I’m not retiring anytime soon and I am gonna get to Australia as soon as I can. You remain in my heart and Thank you for your continued love & support.

Love,
Madonna
