Have you ever been woken by scratching, thumping, or growling above your ceiling during the night? These disturbances are often caused by possums — native marsupials that are strictly nocturnal. In Sydney, brushtail and ringtail possums are most active after sunset, making them a common cause of nighttime noise complaints in suburban areas.
Understanding their nocturnal behaviour is key to managing possum activity around your home. This article explains what possums do at night, why they’re so noisy, and what you can do about it.
Why Are Possums Nocturnal?
Possums have evolved to be nocturnal for several reasons:
- Protection from predators: By foraging at night, they avoid birds of prey like eagles and hawks.
- Cooler temperatures: Nighttime conditions reduce the risk of dehydration during foraging.
- Low competition: Fewer animals compete for food during the night.
While this behaviour benefits possums in the wild, it often brings them into conflict with homeowners in urban settings — especially when they decide to nest in roof cavities or garages.
When Do Possums Wake Up and Become Active?
Possums typically become active shortly after sunset and stay awake until just before sunrise. During this time, they leave their nests to:
- Forage for food
- Mark their territory
- Search for mates (especially during breeding season)
- Defend their nesting site from intruders
Most homeowners hear them between 8:00 PM and 4:00 AM, with peak activity around midnight. If possums are living in your roof, this is when you’re most likely to hear scratching, heavy walking, or growling noises.
What Noises Do Possums Make at Night?
Possums are not quiet animals. Depending on the species and situation, they can produce a variety of sounds:
- Thumping: From walking or running across roof beams
- Scratching: While climbing, digging, or nesting
- Growling or hissing: Territorial disputes between brushtail possums
- High-pitched clicking: Common with ringtail possums communicating with family members

Though rare in urban areas, Feathertail Gliders are active during the night, leaping from branch to branch using their gliding membrane.
Their enhanced low-light vision allows possums to travel rooftops, fences, and tree canopies after dark. Learn more about possum night vision and eye shine and why their eyes glow in torchlight.
What Are Possums Doing While You Sleep?
During the night, possums are busy with survival behaviours. In suburban environments, they often:
- Travel along fences, powerlines, or rooftops
- Rummage through fruit trees, compost bins, or pet food bowls
- Enter roof spaces to nest or shelter
- Look for mates during breeding season (spring and summer)
Because they are creatures of habit, possums will often follow the same routes and schedules each night — which explains why noises above your ceiling may happen at the same time every evening.
Which Possums Are Most Active at Night?
In Sydney, the most active species at night include:
- Brushtail Possums – Loud, solitary, and territorial
- Ringtail Possums – Social and often found in family groups
While sugar gliders and pygmy possums are also nocturnal, they are less commonly found in suburban roof spaces.
Why You Shouldn’t Ignore Nocturnal Possum Activity
Although possums are protected native animals, they can still cause significant property damage. If left unchecked, nighttime possum activity may lead to:
- Urine and droppings accumulating in insulation or ceiling voids
- Chewed electrical wiring or plasterboard
- Disturbed sleep and stress for residents
It’s essential to identify the entry point and address the issue legally. For a detailed guide, read Signs You Have a Brushtail Possum in Your Roof.
Is It Legal to Remove Possums at Night?
No — in NSW, possums are protected under the Biodiversity Conservation Act 2016. Only licensed handlers can remove them, and only between dusk and one hour before sunrise. Additionally, they must be released within 150 metres of the capture site.

How to Minimise Night-Time Possum Activity
While you can’t change possum sleep cycles, you can make your property less appealing. Here’s how:
- Trim trees that provide roof access
- Install possum-proof mesh over vents and chimneys
- Remove outdoor food sources (pet bowls, fruit trees, open bins)
- Seal all known access points with metal sheeting or heavy-duty mesh
