The successful pooch will replace the world-famous Bear, credited with saving over 100 koalas from bushfires during a decade of service.

“Bear set the gold standard for koala detection dogs,” the International Fund for Animal Welfare (IFAW) Oceania head of programmes Josey Sharrad said.

“He’s leaving very big boots to fill, but now it’s time to find his successor to follow in his pawprints and keep protecting koalas.”

The ideal candidate will be a rescue pup with a lot of energy and an “obsessive” personality — attributes that might make it hard to find a home but which make it perfect for saving koalas, IFAW said.

“By only recruiting a rescue dog, it’s a win-win — giving a dog the chance of a new life while helping our iconic koalas,” Innovation for Conservation director and handler Russell Miller said.

Other key attributes are a love of play, confidence and a gentle temperament towards fellow animals is crucial.

They must also be medium sized — “not too small that they struggle in the bush, not too big that the handlers can’t carry them when needed”, according to the IFAW job ad.

Interviews were being held in eastern Australia’s Sunshine Coast but applications by video are also welcome.

Bear’s skills saved over 100 koalas as the Black Summer bushfires raged across Australia’s eastern seaboard from late 2019 to early 2020, razing millions of hectares, destroying thousands of homes and blanketing cities in noxious smoke.

The tail-wagging detective with a “joyful and goofy” personality retired with an extensive list of accolades — including an Animal of the Year award and Puppy Tales Photos Australian Dog of the Year award.
