TL;DR: Getting rid of possums properly means using a humane, legal method that gets them out safely and stops them getting back into your roof. The real fix is not just removal, but proofing your home so the problem does not keep coming back.
Key Takeaways:
If you are searching for how to get rid of possums, the first thing to know is that the job is not about harming them or moving them elsewhere. In Australia, possums are protected native animals, so the right fix is to remove them safely and stop them getting back in.
That is where many homeowners get stuck, because the noise may stop for a night and then start again. A lasting result comes from fixing what attracted the possums in the first place, which is usually shelter, easy access, and an open entry point.
You can deal with a possum problem, but you need to do it lawfully and humanely. Possum rules vary by state, and that matters because a method that sounds simple can be illegal, ineffective, or both.
In Victoria, common brushtail possums trapped in buildings generally must be released on the same property within 50 metres of where they were captured. In Queensland, trapping possums is generally illegal unless you hold the right permit, which is one reason professional help is often the safer path.

Homeowners often spend money on DIY tricks that sound convincing online but do very little in real life. Possums are adaptable, so anything that does not remove shelter or block access usually stops working quickly.
Common fixes that rarely solve the problem include:
These may bother a possum for a while, but they usually do not solve a roof infestation. If the warm, dry nesting spot is still there, the possum often just gets used to the disturbance.
Trapping may seem like a simple fix, but on its own it rarely solves the problem. If the possum is released nearby, it can return through the same opening. Without proper proofing, trapping often leads to repeat callouts and ongoing roof access issues.
A common mistake is fixing the most obvious gap and thinking that will solve it. Possums can test other weak spots around the roof, so blocking one entry often just sends them elsewhere. Good proofing looks at the whole home and seals the easy access points.
If you want to know how to get rid of possums properly, the answer is usually humane exit plus proofing. That means letting the possum leave safely, then making sure it cannot re-enter the building.
This approach deals with the problem at its source instead of chasing symptoms. It is also the option that makes the most sense for homeowners who want quiet nights without the stress of the issue returning next week.
Heavy thumping, deep scratching, and movement across the ceiling at night often point to possums, not rats. You may also notice smells, droppings, stains, or damage near roof entry points. Correct identification matters, because the right treatment depends on what is actually living in the roof.
A proper inspection checks roof edges, eaves, vents, plumbing gaps, damaged tiles, loose sheets, and nearby tree access. The loudest noise is not always where the possum is getting in, so missing even one entry point can keep the problem going.
A one-way door is a simple way to get possums out of your roof without causing extra stress. It lets the possum leave at night as usual but stops it from getting back inside, making it a humane and practical option.
Once the main entry is handled, all remaining gaps must be sealed with durable materials like metal, mesh, or timber. This step is what makes the solution last. Without proper proofing, possums can return easily and the problem often starts again.
A follow-up visit makes sure the final opening is sealed once the possum is out. It also confirms the proofing is holding and there are no signs of re-entry. That last step helps turn a short-term fix into a proper long-term solution.
Once possums are out, prevention becomes the priority. You want to make your property less inviting without creating a bigger problem for yourself or the wildlife around you.
Simple changes around the home can make a real difference, especially when they support proper proofing work. The goal is to reduce shelter opportunities, food rewards, and easy travel paths.

Some possum problems are beyond the stage of DIY advice. If you are hearing repeated roof noise, noticing damage, smelling urine, or seeing signs around multiple entry points, a professional inspection can save you a lot of wasted time.
You should also get expert help if you are unsure about the legal rules in your state, if the access point is high or unsafe, or if you suspect there may be young possums involved. This is not a job where guesswork usually pays off.
Many people try a few cheap fixes first, then end up paying more after the problem returns or the damage gets worse. Roof repairs, stained plaster, chewed wiring, and repeat callouts can add up quickly.
A proper service focuses on the full result, which is removal, proofing, and follow-up. That gives you a better chance of solving the issue once instead of circling around it for months. If you want to see how this works in practice, you can learn more about professional possum removal.
