Hi Mel,
Your poor daughter, I am so sorry she is suffering so much. We don't have a Migraine specialist listed for Australia, but I can direct you to a site that may be able to help you, because it is time to see a REAL Migraine specialist, not just a neurologist. Check this site.
A single Migraine that lasts 72 hours or longer with less than a solid four-hour pain-free period, while awake, is termed status Migrainous. You should see your doctor or go to the emergency room if a Migraine lasts that long. See Status Migrainous - The Basics for more information.
Let us know how your daughter is holding up.
Good luck
Nancy
