Orange-bellied Parrot

Neophema chrysogaster

With fewer than 50 wild birds remaining, the Orange-bellied Parrot is Australia's most critically threatened species — and one of the most remarkable migratory birds on Earth. Each winter, a handful of survivors cross Bass Strait to the salt marshes of Victoria and South Australia.

The Orange-bellied Parrot (Neophema chrysogaster) is one of the rarest birds on Earth — and one of the most poignant conservation stories in Australia. An estimated fewer than 50 wild birds now survive, supplemented by a captive insurance population that actively supports wild recruitment through release programs.

The species breeds only in the remote buttongrass moorlands of southwest Tasmania, nesting in hollows of ancient eucalypts in an area around Melaleuca, a remote wilderness accessible only by light plane or multi-day bushwalk. After breeding, the entire wild population migrates across Bass Strait to winter on the salt marsh and coastal heathland of southern Victoria and South Australia — a crossing of over 250 km over open ocean.

Males are electric grass-green with a vivid orange belly patch framed by blue on the forehead and leading edge of the wing. Females are duller, with a paler orange belly that can be absent in immatures. In the field, birds are best located by their sharp, buzzy calls as they move low through saltmarsh vegetation.

Wintering birds can be found at a small number of reliable sites, most accessibly at Werribee Treatment Plant and Altona/Laverton coastal wetlands near Melbourne, and at Milang, Coorong, and Mount Compass in South Australia. Sightings are never guaranteed — finding this bird requires dedication, good site knowledge, and sometimes patience across multiple days.

Captive breeding at multiple zoos and wildlife centres across Australia has proven essential for the species' survival, and releases of captive-bred birds into the wild have helped maintain the wild population.

Best places to see the Orange-bellied Parrot

1

Werribee Treatment Plant

VIC

The most reliably productive winter site. Coastal wetlands adjacent to the treatment plant support wintering birds Nov–Apr. Join organised survey days for guided access.

2

Altona / Laverton coastal wetlands

VIC

Samphire-dominated salt marsh on Port Phillip Bay. Less traffic than Werribee but productive when birds are present.

3

Milang / Coorong

SA

SA wintering sites. Coorong lagoon edges and Milang foreshore saltmarsh. Requires local knowledge.

4

Melaleuca, Southwest National Park

TAS

The breeding grounds. Accessible only by small plane (light aircraft charter) or a 4–5 day bushwalk. The most committed birders make this pilgrimage each summer (Nov–Feb).

Key facts

  • Fewer than 50 wild birds remaining — one of Australia's rarest vertebrates

  • Crosses Bass Strait (250+ km of open ocean) twice a year on migration

  • Breeds only at Melaleuca in remote southwest Tasmania

  • The orange belly patch is diagnostic — no other small parrot in southeastern Australia has this

  • Active captive breeding programs at Healesville Sanctuary, Melbourne Zoo, and other facilities
