This helps keep island populations under control while reestablishing koalas to some of their former range. But there are two problems with this translocation procedure. New approaches must be made. For example, on Kangaroo Island experts want to solve the overpopulation problem by developing sterilizing techniques instead of translocating the koalas. A few people are in favor of a culling technique, but it is unlikely that koala-lovers will allow that to happen anytime soon.
Today there are several groups working to save the koala.
The Koala Hospital, founded in 1973, takes care of sick or injured koalas that people find. In general, conservation efforts have increase dramatically this century in Australia. Islands are playing an important part in marsupial conservation. Tasmania became a refuge for the Tasmanian devil and the thylacine when dingoes replaced them on the mainland. The red-bellied pademelon, eastern bettong, and eastern quoll also found a safe haven there when their mainland populations became extinct.
