A thump in a Melbourne roof after dark is often a common brushtail possum, not a rat. That distinction is legal as well as biological. Possums are protected under the Wildlife Act 1975. You must not harm them or keep them without approval. Wildlife Victoria and DEECA’s methods page are the primary sources for what a householder may do.
What you may do in a building
Common brushtail possums living in a building may be humanely trapped under the Governor in Council order those pages describe. The trap must not injure the animal. The possum must be released on the same property, no more than 50 metres from the capture site, after sunset on the day of capture. Relocation off the property is prohibited. Research summarised on those pages is why: possums released into a new territory are often attacked and may die.
If it is not reasonably possible to release the possum on the property, the animal must be humanely destroyed by a registered veterinary practitioner, at the trapper’s expense, within 24 hours of capture. That is a hard sentence. It is also the rule. A “nice creek down the road” is not a legal third option.
Who may do this work, on the Wildlife Victoria page, includes home-owners or occupiers and their families, building managers or their staff, and DEECA-licensed wildlife controllers.
Exclusion after the animal is out
Watch where the possum leaves after dark. Fit a one-way flap so it can exit and not return. Prune branches so they do not bridge to the roof — the Wildlife Victoria page mentions leaving a gap of at least 1.5 metres. Collar trees, fix loose tiles and broken eaves. Do not seal the last hole while the animal is still inside.
Garden damage is a different conversation: floppy fences, tree collars and, in some cases, low-powered electric fencing are the non-lethal methods DEECA describes. Lethal control of wildlife is a last resort and needs an Authority to Control Wildlife after practical non-lethal options are exhausted.
What a pest-control licence does not do
A Victorian pesticide technician licence does not replace wildlife law. If someone offers to “relocate possums to the bush” as a standard package, that offer is at odds with the published rule. Ask whether they are a licensed wildlife controller and whether the plan is same-property release plus exclusion.

A night watch that prevents a cruel mistake
Sit outside at dusk with a torch you do not shine in the animal’s face. Watch the exit. Count whether more than one animal leaves. Fit the one-way flap over that hole, not over a hole you guessed. The methods page is explicit about flaps, pruning and the 50-metre rule. Read it before you buy a trap.
Traps, timing and vets
If you trap, check by sunrise. Keep the trap sheltered. Release on the same property after sunset, within 50 metres. If you cannot, the published path is a registered vet within 24 hours, at your expense. That sentence is why many people choose exclusion-only once the animal is out, rather than trapping at all.
A pesticide technician who does not also hold the right wildlife authority is the wrong contractor for this paragraph. Ask the question out loud.
Gardens, floppy fences and ATCW
Garden browsing is usually an exclusion job: floppy fences, collars, nest boxes placed where you can tolerate them. Lethal control is an ATCW conversation after non-lethal options are exhausted. Do not skip to a gun or a poison because a shopfront sold “possum removal”.
Ringtail possums and other species
The published householder trapping pathway described on the Wildlife Victoria page is about common brushtails in buildings. Other species and other situations can be stricter. If you cannot identify the animal, treat it as protected and ask a licensed wildlife controller or Wildlife Victoria, not a general spray van.
Reading the order before you buy a trap
The Wildlife Victoria page and the methods page are short enough to read in one sitting. The 50-metre rule, the sunset release, the vet-within-24-hours path and the ban on off-site relocation are all there. This guide exists to stop people skipping those sentences.
Exclusion after a night watch is often the kinder plan: flap, prune, fix the tile. Trapping is lawful in the published circumstances and still ends in same-property release or a vet. There is no creek option.
Lethal ideas without an ATCW are how people leave the legal path. A pesticide licence is not that authority.
Field notes: possums
What to look for first
Before anyone opens a product, look for this: A dusk exit from a roof where a plane tree touches the gutter. Write the date and the room. That note is what you hand a licensed person, not a vibe.
A first look that costs nothing: A drey of leaves in insulation rather than shredded rodent nesting. If you cannot see it safely, stop and photograph from the doorway.
Melbourne houses hide harbourages. Start with this one: More than one animal leaving the same hole. Then decide whether you are still in a DIY sentence.
Before anyone opens a product, look for this: A garden fence possums walk like a highway. Write the date and the room. That note is what you hand a licensed person, not a vibe.
A first look that costs nothing: A hole you were about to foam while the animal was still inside. If you cannot see it safely, stop and photograph from the doorway.
What not to do
Skip this common mistake: Driving a trapped possum to a creek or a reserve. The archived shopfront loved shortcuts. This rebuild does not.
Do not do this, even if a neighbour swears by it: Putting rodenticide in a roof you have not identified. If a method is not on a label or an agency page, it is folklore.
The wrong move on this job is Sealing the last hole at 4 pm before the night watch. Undo is harder than wait.
Skip this common mistake: Hiring a pesticide-only van for ‘possum relocation’. The archived shopfront loved shortcuts. This rebuild does not.
The rule you can quote
The official line to keep in your pocket: Wildlife Victoria: same-property release, 50 metres, after sunset, or a vet within 24 hours. Quote the agency, not this domain, if you need a rule to stand up.
When the conversation turns legal, use this: DEECA methods: one-way flaps, pruning, no off-site relocation. We are an editorial site. They are the source.
Read the primary page, then this sentence: Lethal control of wildlife needs an ATCW after non-lethal options. If they disagree, the agency wins.
How Melbourne housing changes the job
In this kind of Melbourne building: Inner-north and eastern trees make roof possums ordinary. Copying a slab plan onto a stump house, or a tower plan onto a cottage, is how people buy the wrong product.
Housing stock does the work here: Western slabs still have eaves and still hold animals. The suburb name is a weaker clue than the hatch, the chute or the deck post.
Walk the building type, not the postcode: A terrace party wall can send sound that is not your roof — watch the exit.
After the first night
After the immediate mess: Fit the flap on the hole you watched, then prune the 1.5-metre gap the agency page describes. That is maintenance, not a second panic spray.
The next week is for this, not for a new fog: Check a trap by sunrise and keep it sheltered if you used one. If the animal returns, you have information, not a failed personality test.
File this with the house papers: Fix the tile so the next possum does not inherit the same eave. The next buyer or the next inspector will ask.
