A WA zoologist is spearheading a fundraising drive that will take Australian tourists to see highly endangered species in Indonesia.
"It's a rare opportunity, it's not available to the average tourist in Indonesia," Perth Zoo primate expert Clare Campbell said.
Ms Campbell will lead the inaugural Wildlife Asia Big 5 tour, a nine-day trip to see five highly endangered species in jungles and mountainous regions of Indonesia.
Travellers will be taken behind the scenes, including a captive breeding centre for the Sumatran rhino and the rehabilitation centre for the silvery gibbon.
They will also be taken to see them in the wild, largely impossible for most travellers because of the restrictions on access to the endangered species' habitats.
Animals on the itinerary include the Bornean orang-utan, Sumatran rhino, sun bear, silvery gibbon and Asian elephant.
Wildlife Asia was formed last year from four well-established Perth conservation groups and aims to raise awareness of critically endangered species in Asia, with a focus on Indonesia.
Travellers pay their own way and are encouraged to try to raise $1000 in sponsorship to donate to Wildlife Asia. There are a couple of places left for the March trip.
Perth Zoo also provides funds and expertise to protect threatened species in the wild.
The zoo has raised more than $1.5 million through its Wildlife Conservation Action program for conservation projects with many of the endangered animals.
