This seems like a pretty good Q&A on the Greek economic situation, worth a look.
Protests are great if we have a clear outcome to propose and they take time to organize, more than a couple of days.
My thinking is that maybe we can get into contact with some greek NFP's that are dealing with the arse end of the financial bust and try to promote ZM in Greece from the ground up.
Another option perhaps to compliment direct contact with Greek NFP's might be to connect with multicultural & refugee NFP's in our respective capital cities and see what we can do to support them here in OZ.
Any other ideas?
