The greater bilby is a threatened species. They've been extinct in NSW for more than a decade due to habitat loss and introduced predators.

The 110-hectare sanctuary will provide information on the management of the greater bilbies with the goal of reintroducing them into the wild.

Four females and four males have been released in the sanctuary after undergoing quarantine and health assessments. They've also been fitted with tracking devices.

Taronga Western Plains Zoo's manager of conservation and recovery programs Andrew Elphinstone said the bilbies had all settled into the yard well. 

"We have been able to track each to their burrows and are monitoring them daily via CCTV footage," he said.

"The bilbies are set to be released into the sanctuary in the next month following final confirmation that no invasive predators and competitors such as cats, foxes and rabbits remain in the area."

The eight bilbies will be monitored via their tracking devices and burrow cameras. They will also undergo physical check-ups for health assessments throughout the year.

Dubbo MP Troy Grant said the arrival of the bilbies was the next step in the zoo's commitment to help save the species from extinction. He said they couldn't be in safer hands. 

The bilbies will eventually be released into Sturt National Park, as part of the Wild Desert project, in the north-western corner of NSW.

Taronga is dedicating the next ten years to the conservation of ten critical species, including the greater bilby.
