Eastern Pygmy Possum: Identification, Habitat & Legal Protections in Sydney
The Eastern Pygmy Possum (Cercartetus nanus) is a tiny, nocturnal marsupial found in bushland around the edges of Sydney. Rarely seen and easily mistaken for a rodent, this possum plays an important ecological role as a pollinator. It is a fully protected species in New South Wales and must be handled with extreme care if encountered.
In this guide, we explain how to identify an Eastern Pygmy Possum, where they live, and what to do if you find one near your home or garden.
Quick Facts About the Eastern Pygmy Possum
- Scientific name: Cercartetus nanus
- Size: 7–11 cm body length with an 8–10 cm tail
- Weight: 15–45 grams
- Habitat: Heathlands, sclerophyll forests, and dense shrubs
- Diet: Nectar, pollen, insects
- Status: Threatened and protected in NSW
How to Identify an Eastern Pygmy Possum
Eastern Pygmy Possums are easily confused with mice or baby rats due to their small size. However, they have several distinctive features:
- Rusty-grey to cinnamon-coloured fur with a pale underbelly
- Large eyes adapted for nocturnal vision
- A prehensile tail used for climbing and balance
- Pointed snout and small rounded ears
- No gliding membrane (unlike sugar gliders)
They are rarely seen unless accidentally uncovered in shrubs or when caught by cats. If you’re unsure whether you’ve found a pygmy possum or a rodent, do not attempt to handle it. Call a wildlife expert immediately.
Other small native possums such as the Feathertail Glider are often confused with pygmy possums due to their size but differ significantly in behaviour and tail structure.
The Eastern Pygmy Possum is usually light brown or grey, but rarely varies much in colour. For contrast, see how other possums’ fur colours differ across species.

Where Are They Found in Sydney?
Eastern Pygmy Possums are not commonly found in built-up suburbs but may appear in fringe areas that border bushland, such as:
- Blue Mountains region
- Royal National Park
- Ku-ring-gai Chase National Park
- Heathcote, Hornsby Heights, and Berowra
They live in low shrubs and tree hollows, often nesting in banksia, tea trees, and grevilleas where nectar is abundant. Their presence may indicate a healthy local ecosystem.
Why Are They Important?
Despite their small size, pygmy possums are critical pollinators. They feed on nectar and pollen from native flowering plants, transferring it between species in a way similar to bees.
Without pygmy possums, many Australian plant species would struggle to reproduce. This is one of the reasons they are fully protected in NSW.
Are Eastern Pygmy Possums a Pest?
No — pygmy possums do not cause damage, enter homes, or nest in roofs like brushtails or ringtails. If one is on your property, it is either sheltering in your garden or has been displaced due to habitat loss.
They are more likely to be injured by domestic pets or displaced by clearing or construction. They do not pose any threat to property, pets, or people.
Legal Protection in NSW
The Eastern Pygmy Possum is listed as a threatened species under the NSW Biodiversity Conservation Act 2016. This means:
- It is illegal to capture, move, or harm a pygmy possum
- Only licensed wildlife handlers may care for injured individuals
- Removing plants or clearing areas where they nest may require a permit
For more details, refer to Protected Possums in NSW or our Possum Removal Laws page.
What to Do if You Find a Pygmy Possum
If you discover a pygmy possum on your property — especially if it appears injured or disoriented — follow these steps:
- Do not touch or move it unless it is in immediate danger
- Keep pets and children away from the area
- Contact a licensed wildlife rescue organisation or call Possum Ranger
Our trained team can identify the species, assess any risks, and ensure safe transfer to an approved wildlife carer if needed. Do not attempt to trap or relocate the animal yourself.
Can They Enter Homes or Roofs?
It’s very rare, but not impossible. A pygmy possum may end up in a shed or garage if its habitat has been cleared or disturbed. They may also be found in garden equipment, bins, or potted plants left outdoors.
If you suspect you have a possum in your home, it’s more likely a Common Brushtail Possum or Ringtail Possum.
Prevention Tips
To avoid accidental harm to pygmy possums on your property:
- Trim vegetation slowly and check shrubs before pruning
- Keep cats and dogs indoors overnight, especially near bushland
- Avoid using pesticides that could affect their food sources
- Protect flowering plants and trees that attract nectar feeders
If you’re unsure what’s nesting in your garden, book a wildlife inspection with our team.
