After spending her entire life in captivity at Perth Zoo with her mother, Puteri, she will travel next week to her new home in the rainforests of Indonesia.
She will be released into a protected Indonesian national park as part of an international effort to re-establish a population of the critically endangered species.
A team of veterinarians, keepers and zoo officials have spent the past year meticulously planning and preparing for the much anticipated transfer.
Temara, hand-picked for the role based on her age, sex, health and temperament, has recently been introduced to Indonesian fruits, live termites and the wide variety of leaves she'll encounter in the wild.
She had also been given access to a high fig tree to hone her climbing and nest-making skills and improve her fitness and muscle tone.
Temara will be carefully monitored for at least 12 months to assess how she adjusts.
Perth Zoo has the capacity to breed Orangutans for release into the wild on an ongoing basis, depending on how things pan out with Temara.
It is believed there are only 7,300 Sumatran Orangutans left in the wild. They are the slowest reproducing species on earth and face extinction in the wild within 15 years.
