Possum removal: the legal way to get rid of possums in your roof

What does possum removal cost?

Possums are protected: killing or driving one away is illegal

Every Australian state protects possums under wildlife law. In NSW, it's the Biodiversity Conservation Act 2016.1environment.nsw.gov.auView source In QLD, the Nature Conservation Act 1992.3qld.gov.auView source Each state has its own laws covering the same core rule: you can't trap, handle, or move a possum without a current licence. A homeowner who sets a cage trap and drives the animal to a bush reserve is breaking the law, even meaning well.2environment.nsw.gov.auView source

Possum removal is the clearest case where the law makes the call for you. If you're wondering when to call a licensed pest controller versus trying to handle a pest yourself, you don't need to weigh it up here.

State laws differ on distance, but all states ban unlicensed trapping

The key rules are the same everywhere: possums are protected, a licence is needed, and the animal must go back on or very near your property. The exact release distance varies by state. In NSW, the possum must be released at dusk, no more than 150 metres from where it was caught, and near something it can climb straight away, like a tree or a tall fence.1environment.nsw.gov.auView source In QLD, the rule is tighter: the possum must go back within 25 metres of where it was trapped.3qld.gov.auView source That's basically the same yard.

In Victoria, possums are protected under the Wildlife Act 1975. Your pest controller will know the current rules for your location. The state's wildlife body sets these, and they can vary by species.

The table below sets out what's confirmed for NSW and QLD. For VIC, your pest controller is the right person to ask.

Driving a possum to a park is illegal and usually fatal for the animal

The urge to take it somewhere nicer makes sense, but it usually kills the animal. Possums know every tree, food source, and shelter in their home range. Drop one into a park where another possum already lives and it's competing for things it can't find, in a place that's already taken.1environment.nsw.gov.auView source

The NSW Environment Department puts it plainly: a displaced possum 'may not survive after being released into a new and unfamiliar territory.'1environment.nsw.gov.auView source That's why the law requires on-property release. It's the only way the animal has a real chance.

NSW and QLD rules are verified; Victoria's distance depends on your pest controller

NSW and QLD rules are confirmed from direct-fetch government sources. Victoria's rules are set by the Wildlife Act 1975. Ask your pest controller for the current VIC rules.

A licensed pest controller traps, releases on your property, and puts up a nest box

So the law is clear: you need a licensed pest controller. The job has two stages: get the animal out within the law, then close the entry point for good. A pest controller starts with a site visit. They need to find where the possum gets in and plan the release before any trap goes down.

Most controllers visit twice. The first visit is in the evening to set the trap. The second is the next morning to check it. Possums are active at night, so the trap is set at dusk and any caught animal is let go within the time window your state sets.2environment.nsw.gov.auView source In NSW, that means at dusk, back on your property within 150 metres, near a tree or fence the possum can climb right away.1environment.nsw.gov.auView source

Many pest controllers also set up a nest box as part of the job. A timber box mounted in a tree on your property gives the possum a proper home to move into.1environment.nsw.gov.auView source In NSW this is required. Across Australia it's seen as best practice. It helps the possum settle in your yard rather than push back into your roof.

Sealing the entry point is the only lasting fix

Trap and remove a possum and you've solved today's problem. But leave the gap open and you'll have the same problem within a week, possibly with a different possum. Possums look for warm roof voids with easy access, especially in cooler months when they want a safe place to sleep.3qld.gov.auView source

A pest controller can seal the common entry points as part of the same job. Typical methods are steel mesh over open soffits and fascia gaps, timber blocks over broken boards, a one-way door that lets the possum leave but not return, and cutting back branches that give roof access.1environment.nsw.gov.auView source 3qld.gov.auView source The one-way door is safest when you're not sure the possum has left. It can get out freely and can't come back, at which point the controller seals the gap for good.

The proofing can be done as part of the removal job or quoted on its own. Ask your pest controller to look for entry points at the first visit. Catching a second gap then costs nothing. Fixing it after another animal moves in costs a lot more.

What pushes possum removal costs up or down

Access is the biggest cost driver. A standard roofline job, where the pest controller can reach the void from a ladder or from ground level, is the simplest and cheapest case. The price goes up when the possum is in a tight space: a narrow attic void, a subfloor, or an internal wall. Those jobs take more time and often need special gear.

The number of possums also matters. Removal is priced per animal. If the controller finds signs of two possums (separate nests, more than one entry point), the job costs more. A follow-up visit is usually part of a standard job, but extra repeat visits are quoted on their own.

Repair work, if the possum has damaged the roof lining or insulation, is a separate job for a builder or roof repairer. A pest controller seals entry points. Major building work is a licensed carpenter's job, priced on its own. For possum removal costs near you, see the pest control cost guide.

Brushtails are the likely roof pest; ringtails are rare inside buildings

Australia has two common possum types that homeowners run into. The Common Brushtail Possum is by far the more likely one in a roof. It's a large, stocky animal with grey-brown fur, a bushy tail, and a hiss that sounds very loud in a quiet ceiling at 2am. Brushtails are happy in roof voids, where they're warm, dry, and safe from predators.3qld.gov.auView source

The Common Ringtail Possum is smaller and builds leafy nests called dreys in dense shrubs or tree forks. Ringtails are less likely to enter a roof, though it does happen. State rules can differ by species, and some states set stricter rules for ringtails than for brushtails. Your pest controller will know what applies in your location.

If you're hearing thumping, scratching, and the odd hiss from your ceiling, it's almost certainly a brushtail. A pest controller can confirm the species at the visit.

Trim branches and seal secondary gaps to stop other possums moving in

Once a pest controller has removed the possum and sealed the main entry point, you can lower the risk further. Here are the steps worth taking.

Trim overhanging branches that give roof access. Possums are excellent climbers but they need a launch point. A branch within a metre of the roofline is an open invitation. Try to keep at least two metres between branch tips and the nearest section of roof or fascia. If your neighbour's tree is the issue, a conversation or a council request is worth trying.

Walk around the outside of your roof in daylight and look for open soffits, loose fascia boards, or gaps around downpipes. Any opening wider than about 10cm is a possum risk.

If there's a good tree on your property, put up a possum box. This gives local possums a place to nest that's not your roof. Your pest controller or local council can advise on where to put it and what type to get.

European wasps can be treated; protected native bees may need a beekeeper instead

Wasps and bees follow a similar pattern to possums in one way: some are protected, and the right response depends on the species. A European wasp nest in the eaves is a job for a licensed pest controller. A native bee colony in a wall cavity might need a beekeeper instead, depending on the species and your state.

The rules around wasp and bee removal, which species can be treated, which must be relocated, and who can do the work, are covered in the wasp and bee removal guide.
