For those of you that don't know. An artist doesn't usually have a wait list through ticketek if they don't have an upcoming show planned.
Rumours have been circulating for some time that Madonna would open her next tour in Australia. The Queen of pop promised Australia the greatest show on earth after the cancellation of the Australian leg of the MDNA tour.
