The golden colour occurs due to a mutation which causes a low level of the pigment melanin which gives them their normal colour.
They are so rare in the wild as although their bright colour makes them look special to us, they also stand out to predators!
Luckily for this baby brushtail she’s gone to carers to be raised and then will end up in a wildlife sanctuary so she can live a long happy life.
