Hi SOMV,
The agent that I was in talks with before also suggested speaking to Martha Baz, however I struggled to get a reply from her and when I spoke to the agent again he dug more and seems to think that she has retired.
Are you thinking that it is a case of the only way you know is to try?
I am only aware of one medical specialist, Dr Martha Baz, who used to provide medical opinions about medical conditions. These were her contact details, and she was so busy she was quite hard to get hold of:
Martha G Baz MB BS MPH FAFOM FAADEP CIME
Lvl 9, 47 York St Sydney GPO Box 3857 Sydney 2001 Australia
Mail from doctors/patients/clients: 138, 272 Victoria Ave Chatswood NSW 2067 Australia
Tel: 61 2 9299 0012
Fax: 61 2 9475 0141
Fax UK: (+44) (0)20 7990 7740
drbaz@visamedicalopinion.com
mgbaz@ozemail.com.au
But these are quite old contact details.
This used to be her website, but it appears not to be working:
http://visamedicalopinion.com/
This seems to be the new alternative:
http://www.visamedic.com/
I'd try to get in touch with her to see if she can help (she does not need to see people in person, but she of course charges for her time and opinion).
Best of luck!
