Identification
Size: The head-to-body length of an adult is typically between 95mm and 200mm. Its prehensile tail is long, measuring 115mm to 210mm, and is usually longer than the head and body.
Color: The dorsal fur is a soft grey-brown, sometimes with a reddish or fawn tint. The underbelly is a clear white, cream, or pale grey. The most prominent colour feature is the feet; the upper surface of the hind feet is covered in fur of a distinct fawn, tan, or cinnamon-brown colour, which gives the species its name. The tail is dark and sparsely haired.
Biology & Lifecycle
Breeding can happen at any time of year but typically peaks in spring and autumn. After a gestation period of about 30-32 days, the female gives birth to a very small litter, usually of two pups. This low reproductive rate is a key difference from introduced pest rats. The female will construct a well-hidden nest for her young.
Lifecycle Details
Fawn-footed Melomys have a relatively short lifespan in the wild, likely averaging 1-2 years. They reach sexual maturity within their first year. As tree-dwellers, they face threats from arboreal predators like owls and pythons.
Habitat & Distribution
- Tropical and subtropical rainforests.
- Wet sclerophyll forests with a dense, shrubby understorey.
- Coastal heathlands with thick vegetation.
- Dense vegetation along creeks and rivers.
- Banana plantations, where they can find food and shelter.
Distribution Patterns
Found along the coast and adjacent ranges from near Cooktown in northern Queensland, south through eastern Queensland and eastern New South Wales to the Hawkesbury River, just north of Sydney.
Behavior & Diet
Strictly nocturnal. It emerges at dusk to forage in the trees and shrubs, returning to its nest to rest before dawn.
Dietary Preferences
An omnivore with a strong preference for vegetation.
Health Risks
Always consult healthcare professionals for medical concerns related to pest exposure.
- No significant public health risk. As a wild animal that rarely enters homes, the chance of disease transmission is extremely low.
Economic Impact
Professional Treatment: Not applicable, as it is a protected native species.
Prevention Costs: Costs would relate to sealing entry points to buildings in rural areas to prevent accidental entry.
DIY Treatment: Illegal.
Structural Damage: Does not cause structural damage. In rare cases, it might nest in a roof void or shed if it gains entry from adjacent bushland.
Food Contamination: No significant risk.
Equipment Damage: None.
Restaurant Issues: None.
Retail Impact: None.
Reputation Damage: None.
Detection & Signs
- Distinctive fawn, tan, or cinnamon-coloured fur on the tops of the hind feet.
- A long, prehensile, mosaic-patterned tail, often longer than the body.
- Large, dark eyes and a slender, agile body for climbing.
- Builds a spherical nest of leaves above ground.
- Found along the east coast of Australia in wet forests.
Prevention
- Not relevant for this species in its natural habitat.
- If living near bushland, general sanitation like securing compost bins and not leaving pet food out will reduce the attraction for actual pest species, which is good practice.
- To prevent the rare, accidental entry into a building, seal all gaps and holes, especially around the roofline and eaves, as they are climbers.
- Trim branches that overhang or touch the roof.
- Install screens on windows and doors.
- These are general measures to pest-proof a home in a rural or bushland setting.
- To support this native species, plant a variety of local native trees and shrubs that provide flowers and fruit.
- Maintain habitat complexity with multiple layers (ground cover, shrubs, trees).
- If you need to discourage them from one specific area, like a fruit tree, netting the tree is the most effective method.
- Do not clear dense vegetation unnecessarily.
Control Methods
Chemical Control: Illegal, unethical, and unnecessary for this protected native species.
Physical Control: If one is trapped inside a building, it should be live-trapped using a cage trap and released back into the adjacent bushland. This is a job for a licensed wildlife handler.
Integrated Approach: The only approach is coexistence. Seal entry points to your home and appreciate the animal's presence in its natural habitat next door.
Mechanical Control: Live-trapping should only be done by experienced handlers to avoid injuring the animal.
Natural Remedies: Not applicable.

A peak breeding season. Increased foraging on new leaves, flowers, and nectar. Very active in the canopy.
Activity remains high. Young from spring litters become independent. Foraging focuses on ripening fruits.
A second peak in breeding activity often occurs. Foraging for fruits and seeds continues.
Activity levels may decrease, especially in the southern parts of its range. They rely more on leaves and bark for food.
Can breed year-round, but generally peaks in spring and autumn.
Legal Considerations
Professional pest control operators must be licensed and comply with relevant regulations regarding mouse control treatments.
Frequently Asked Questions
Is the Fawn-footed Melomys a pest I need to control?
No, the Fawn-footed Melomys is a protected native Australian animal and should not be controlled. It is a shy, forest-dwelling creature that plays a natural role in its ecosystem. While its nickname 'Banana Rat' suggests it is a pest of agriculture, the actual economic damage it causes is minimal and very localised. It does not infest homes or properties in the way introduced rats do. Harming this species is illegal. The best approach is to appreciate it as part of Australia's unique wildlife and, if you live adjacent to its habitat, ensure your home is sealed to prevent accidental entry.
How can I tell the difference between a Fawn-footed Melomys and a Black Rat?
There are several key differences. The most obvious is the feet: the Fawn-footed Melomys has distinctive fawn or cinnamon-brown fur on its hind feet, whereas the Black Rat has dark grey or black feet. Second, look at the tail. The melomys has a long, prehensile tail with a fine, mosaic-like scale pattern. The Black Rat's tail has coarse, overlapping scales that look like rings. Finally, observe behaviour. The melomys is a confident, fluid climber in its forest habitat. The Black Rat is also a good climber but is more commonly associated with buildings and human structures. If you see a rodent in your roof, it's a Black Rat; if you see one in a rainforest tree, it could be a melomys.
Why do they build football-sized nests in trees?
The spherical nest is the Fawn-footed Melomys' home and nursery. Building it above the ground in a tree fork or dense shrubbery provides protection from ground-dwelling predators and flooding. The nest is expertly woven from shredded leaves, grass, and bark, making it waterproof and well-insulated. This provides a safe, dry, and warm place for the melomys to rest during the day and for the female to raise her very small litter of one or two pups. Finding one of these nests is a clear sign that a melomys is living nearby.
I live next to a national park and saw a melomys in my shed. What should I do?
Finding a native Fawn-footed Melomys in your shed is a rare event that indicates your property is very close to good quality habitat. The animal has likely entered by accident and is not looking to stay. It poses no threat. The best course of action is to ensure it can leave on its own. Open the shed door in the evening and leave it open overnight. The nocturnal melomys will almost certainly find its own way out and return to the bush. Afterwards, the most important step is to find and seal the entry point it used—check for gaps under the door, holes in walls, or openings near the roof—to prevent it or other animals from entering again.
What is the conservation status of the Fawn-footed Melomys?
The Fawn-footed Melomys is currently listed as a species of 'Least Concern' on both a federal and state level. This means that, at present, it is not considered threatened with extinction. However, this status relies on the continued existence of its preferred habitat. The main threats to its long-term survival are the clearing and fragmentation of the coastal rainforests and wet sclerophyll forests it calls home. Therefore, the protection of these habitats from urban and agricultural expansion, as well as managing threats like inappropriate fires and predation by feral cats, is crucial to ensure this fascinating native climber continues to thrive.
