Health insuranceHi...

Health insurance Hi everybody. I am just to start my MC-IOF in Australia. My host institution is INRA in France and I am having a lot of problems with the health insurance. I cannot get the visa without it and my institutions is not clear about which kind of health coverage I will have during my outgoing phase. Does anybody have any experience dealing with this problem? I have asked about paying with overheads (as the EU recommends) but it seems INRA does not follow this guideline.
