Australian wildlife researchers have devised an effective way to protect koalas which they hope could ultimately bring the native animals back from the brink of extinction.
Hundreds of Australian koalas will be vaccinated against chlamydia as part of a trial that researchers say they hope could play a significant role in the longer-term survival of the animals.
