Goodfellow's Tree Kangaroo

Meet Kofi

Dendrolagus goodfellowi

Meet Kofi, our much-loved Goodfellow’s Tree Kangaroo at WILD LIFE Sydney Zoo.

With his fluffy coat, bright blue eyes and impressive climbing skills, Kofi is always a favourite. Goodfellow’s Tree Kangaroos are native to the dense tropical rainforests of Papua New Guinea, where they are perfectly adapted to life high in the treetops.

These unique marsupials use their strong limbs, sharp claws and long tails to climb and balance through the forest canopy. They are herbivores, feeding on leaves, flowers and fruit. Although Kofi is also known to enjoy a boiled egg or two.

When you visit Kofi, you’ll discover more about Goodfellow’s Tree Kangaroos, the challenges they face in the wild, and why protecting rainforest habitats is so important.

Goodfellow's Tree Kangaroo Dendrolagus goodfellowi has most recently been assessed for The IUCN Red List of Threatened Species in 2016. Dendrolagus goodfellowi is listed as Endangered under criteria A2cd.

IUCN Conservation Status

Endangered (EN)

Scientific Name

Dendrolagus goodfellowi.

Alternative Name

Ornate Tree Kangaroo.

Classification

Class: Mammalia

Order: Diprotodontia.

Family: Macropodidae, which also includes kangaroos and wallabies.

Genus: Dendrolagus

Identification and Size

Goodfellow’s Tree Kangaroos have soft reddish-brown fur, golden colouring on their face, limbs and underside, and two distinctive golden stripes along their back. Their long tail helps them balance, while their strong limbs and curved claws help them climb. Adults measure around 55-77cm in body length, with a 70-84.5cm tail and generally weigh between 5.9-9.5kg.

Habitat

They live in dense tropical forests, particularly lower and mid-mountain rainforest. The species has been recorded from lowland areas to elevations of around 2,860 metres.

Distribution

Goodfellow’s Tree Kangaroos are found on mainland Papua New Guinea, particularly along the country’s central mountain ranges from near the Indonesian border towards Milne Bay.

Feeding and Diet


Their diet is mainly made up of leaves, fruit, flowers and other plant material. They may also eat insects and occasional foods such as eggs.

Breeding


A female usually gives birth to one tiny joey. After birth, the joey climbs into its mother’s pouch, where it continues growing and developing for around eight to ten months.

Threats


Goodfellow’s Tree Kangaroos are threatened by hunting and the loss of their rainforest habitat. Forests are cleared or disturbed by logging, mining and agriculture, reducing the food, shelter and connected tree canopy they need to survive. Their slow breeding rate also makes it difficult for populations to recover from declines.

Conservation


The species is listed as Endangered. Conservation efforts are centred on protecting remaining rainforest habitat, reducing unsustainable hunting and limiting further land clearing. Maintaining large, connected areas of healthy forest benefits Goodfellow’s Tree Kangaroos and the many other species that share their habitat.

Who said it was rude to chew loudly? Not a tree kangaroo.

This May, Kofi is putting his crunching skills to the test for the International Tree Kangaroo Crunch-a-Thon!

Running from 11–15 May 2026, the Crunch-a-Thon brings together zoos and conservation organisations from around the world to celebrate one of the cutest tree kangaroo behaviours: munching, crunching and chewing very loudly. It all takes place in the lead-up to World Tree Kangaroo Day on 21 May.

At WILD LIFE Sydney Zoo, we’ve taken part in the Crunch-a-Thon before, and we’re excited to get behind it again with some very snackable content starring our Goodfellow’s Tree Kangaroo, Kofi.

Keep an eye on our social channels for Kofi enjoying his favourite crunchy snacks. Every like, share and view helps shine a spotlight on tree kangaroos and the importance of protecting these incredible animals in the wild.
