Gould's petrel conservation project

Cabbage Tree Island, offshore from Port Stephens, was the endangered petrel’s only known breeding site in the world. In the early 1990s, there were less than 250 breeding pairs raising only 50 chicks a year. The species was heading towards extinction.

To save the species, NPWS started a project to establish a second colony on nearby Boondelbah Island. This internationally ground-breaking project included installing nest boxes to create habitat where none had previously existed. Some of Cabbage Tree Island’s chicks were successfully moved here, and were cared for until they fledged, imprinting the new island as their home.

There is now a well-established petrel colony on Boondelbah Island, where the artificial nest boxes replace the petrel's natural nesting sites like rock crevices, hollow fallen palm trunks, and the buttresses of fig trees in rocky gullies.

In more recent years, NPWS has partnered with Birding NSW to encourage a new breeding colony on Broughton Island.

The long-term habitat restoration project includes installing artificial nest boxes, and a loud speaker playing petrel bird calls, to attraction petrels to the site.

Gould's petrels have started using the nest boxes and chicks have successfully hatched at this new breeding site.

The Gould’s petrel was thought to only breed on the islands off Port Stephens until, in 2012, two Gould’s petrels were heard on Barunguba Montague Island, calling from a burrow.

Today, there’s over 25 breeding pairs on this South Coast sanctuary. Their presence is attributed to the conservation efforts that have seen the Port Stephens populations recover and expand their traditional breeding sites. Successful restoration of seabird habitat and eradication of pest animals (goats, mice and rabbits) on Barunguba have also helped.

Due to these ongoing conservation efforts, Gould’s petrels' breeding habitats are expanding. This remarkable species is being given the best chance to safeguard its survival, under pressure from climate-related changes that impact their natural habitat and at-sea feeding areas.

The project also aims to minimise threats from predatory birds and invasive weed species, the risk of accidental introduction of feral animals on the islands, and human disturbance.

Extra protections

These islands have been declared Assets of Intergenerational Significance (AIS), providing the strongest legal protections for the Gould’s petrel and its breeding sites, to ensure its survival for future generations.

'The Petrel, the Love-box and the Egg' is an innovative augmented reality experience that brings the amazing journey of the Gould's petrel to life in the free NPWS mobile app. Find out more on our Gould's petrel immersive story page.
