Parramatta’s parkland along the river, combined with tree lined streets in the older parts of the suburb, gives possums plenty of places to settle, and roof spaces in nearby homes are often the easiest fallback. The scratching and thumping usually starts around dusk as the possum heads out to feed, then again near dawn on the way back. This page covers why possums end up in Parramatta roofs, how they’re safely encouraged to leave, and how to stop the next one settling in.
Noise at night is the clearest sign, thumping or scratching not long after dark and again closer to dawn. A musty smell near one part of the ceiling, droppings around a manhole, or an obvious entry point around a tile, vent, or eave are worth checking for too.
A roof cavity gives a possum shelter, distance from anything that might see it as a meal, and a short path down to nearby trees at night. Parramatta’s riverside parkland and older tree lined streets put plenty of rooflines within easy reach, so the jump from branch to roof is often straightforward. Once a possum settles somewhere comfortable, it tends to return, which is why the same roof can end up with a new possum before long.
Possums are a protected native animal in New South Wales, so moving one on takes more care than simply chasing it out. The usual approach involves confirming where it’s coming and going from, then fitting a one way door over that entry point so it can leave to feed but can’t get back in the same way. This tends to work within a few nights, and the entry point only gets sealed once it’s confirmed the possum has gone.
Possums are active after dark, so a one way door only works while the possum is out feeding. Checking for young possums matters too, since a mother may be carrying a joey during the cooler months, and rushing the process at the wrong time can separate them.
The entry point that let one possum in will attract another unless it’s properly closed once the roof is clear. Sealing gaps around tiles, vents, and eaves, along with trimming branches that reach the roofline, removes the easiest path from tree to roof.

They’re territorial and tend to return to a shelter spot they know, so unless the entry point is closed properly, a new possum often finds its way back in.
No, sealing while a possum is still inside traps it, which usually causes more damage and a worse smell than the original problem.
They’re around all year, but activity picks up in the cooler months and again during breeding season when mothers are carrying young.
Yes, scratching, nesting material, and urine can affect insulation and ceiling linings over time.
It finds a new spot to shelter nearby, since possums don’t tend to travel far. The job is about getting it out and keeping it out.
Possums are a protected species, and getting the timing or door wrong can trap the possum inside instead of letting it leave, so getting the roof checked properly is usually the more straightforward option.
