@Immanuelcentre,
I replied to your thread earlier but I don't know why did the moderators deleted it. Anyways, any registered charity can operate in its state, country or to some extent in the other countries also. However a validation is required for this process to operate in other countries. Regarding NSW, TCC or DGR, I am not too much sure as I have never heard about them. But will you be some more specific regarding this thing?
