Recently a group of cemeteries in Adelaide, capital of the state of South Australia, have released their burial registers on the internet. The link below includes West Terrace Cemetery (the original Adelaide cemetery and the oldest continually operated cemetery in Australia); Enfield Memorial Park (a cemetery and crematorium); Cheltenham Cemetery and Smithfield Memorial Park (a relatively new cemetery and crematorium).
I have also added the link to Centennial Park, a large cemetery and crematorium in the southern suburbs of Adelaide. http://www.centennialpark.org/
