You need to go to the box at the top of this page which says "Jump to Forum". Type in one of the last names to see if there is a family forum for that name; continue with all your surnames. You can post at each and every family forum you need if there is a forum for the surname.
Also use the same method to go to Italy and Australia. Both of those places should have Counties, Provinces, or whatever that you can go to (hit the "counties listings" at the top of the Italy and/or Australia General listings page.
