Some 20 endangered bridled nailtail wallabies were flown from Queensland to New South Wales in what conservationists described as a “delicate mission” to help bolster one of the “few remaining populations in Australia.”The Australian Wildlife Conservancy (AWC) said the wallabies, once believed to be extinct, were relocated to the Scotia Wildlife Sanctuary in New South Wales “to improve the genetic diversity of the sanctuary’s reintroduced population.”According to AWC, 12 males and eight females were lured into baited traps before getting a health check and being flown three and a half-hours south on a specially-chartered flight.They were released into a predator-free area and fitted with tracking collars to monitor their progress over the next year.
