Gunnedah's chief koala carer has welcomed the news that a new chlamydia vaccine will be trialled in the area next year.
The University of Sydney and the Sunshine Coast are teaming up to run a trial next year in the hope of treating and preventing chlamydia.
Sydney's Dr Valentina Mella and Professor Mark Krockeberger say 65-70 per cent of the Gunnedah population carry the disease, and it will only spread.
WIRES' Martine Moran has seen first-hand the effects of chlamydia, taking countless koalas into care over the years to nurse them back to health.
Even now she is treating infected koalas and says any progress is "good news".
"I think it's fabulous because chlamydia has been around for a very long time and a larger proportion have been affected by chlamydia in recent years," she said.
"Even if it works in the short-term, it may help to save a lot of koalas."
