Hi if you go into Metropolitan Cemetery Board of Western Australia, you can get up to date records of where they died, where buried or cremated, how old when they died. They also have what grave they are in. Also death date.
You put in surname and search for the name.
I comes up Karrakatta, and Fremantle, and other metropolitan area Cemeteries. Country are different put in name of Cemetery where they lived. Also some are cremated at Karrakatta, and then buried in the family grave in the country.
