Step 1
Confirm the animal
Inspect signs, roof access and the building perimeter to distinguish possums from rodents or birds.
Lower North Shore · NSW 2088
Mosman houses often combine steep ground, mature trees and complicated roof lines. A possum may climb to a verandah, cross a lower roof and enter near an upper gable. That path is easy to miss when the inspection stays at street level.
Ask about same-day availability; appointment times depend on capacity and safe access.
On the ground in Mosman
Observe the property from safe ground at dusk and note each change in height. Chimneys, eaves and service gaps around upper additions need attention. In apartments, landscaped common areas and balconies may explain outdoor activity without proving roof entry.
Tall elevations or limited side passages may require specialist equipment. An initial visit can still identify signs and prepare a scope. No one should promise that every gap is sealed when parts of the roof were not safely inspected.
Provide photos from the street and rear where safe. Describe the route, the sound and any sighting of young. Ask for the current NSW possum licence holder if the plan includes a cage or physical capture.
What happens next
Step 1
Inspect signs, roof access and the building perimeter to distinguish possums from rodents or birds.
Step 2
Do not install exclusion until the roof has been checked for dependent animals and other occupants.
Step 3
Use non-harmful exclusion where suitable. Any capture and release must be completed under a current NSW licence.
Step 4
After the roof is confirmed empty, close the identified access points so another possum cannot move in.
Step 5
A correctly positioned nest box can provide alternative shelter while allowing the possum to remain in its territory.
A healthy possum outdoors is part of the local environment. Roof entry is the property problem. Capture and release requires a current NSW licence. Call WIRES or Sydney Wildlife for an animal that looks sick, injured or orphaned.
Yes. Possums are protected under the Biodiversity Conservation Act 2016. Catching and releasing a possum requires a current licence and licence conditions apply.
Same-day inspection may be available depending on technician capacity and safe roof access. Phone to check the next appointment rather than relying on an unconfirmed response-time promise.
A possum or dependent young may still be inside. Sealing too early can trap an animal in the roof. The void must be checked and confirmed empty before permanent proofing.
Current NSW guidance says licensed handlers must release a possum after sunset, on the property where it was captured and within 150 metres of the capture point, against something it can immediately climb.
It should name them. The report can distinguish inspected openings from areas seen only at a distance or not reached at all. That gives the owner a realistic scope and a basis for any follow-up access work.
Call to describe the problem and confirm service-area and same-day availability.
