Hi and welcome to the Chiari forum.
We did start a list of Drs for ur corner of the world...it is by no means a large list as drs names r added by the members....and we do not get as many from down under, but we r trying to keep a list to help...and I also do not know if ne of the Drs r in ur area, u may have to travel to get to a dr that not only knows what chiari is, but is experienced in working with it too.

The list is not a referral, but a means to help u research Drs.
Finding a Dr is a good part of this journey. getting the Dx can be the hard part...so, u r over a good portion of the hump....keep pushing forward.
And just bcuz we r not on ur continent doesn't mean we can't be a sounding board....know u r not alone : )
