A break-in is a shock. The immediate steps matter — and so does what you do in the days after to reduce the risk of it happening again. This guide covers both.
If you are searching for what to do after a break-in in Australia, the most important thing to know is this: previous victims are significantly more likely to be re-targeted. Visible change to your security posture is the single best deterrent.
Most people focus on replacing what was stolen. The evidence says the most urgent job is to signal that your security posture has changed — before someone comes back.
Research from the Australian Institute of Criminology documents that previous victims are among the highest-risk households. The window before security is upgraded is when offenders are most likely to return.

Do not enter a property you believe has been broken into. Call 000 if you suspect someone is still inside, or 131 444 for non-emergency police attendance. Wait outside.
Once police confirm it is safe, photograph everything before cleaning up or moving items. This is critical for your insurance claim and for police evidence.
A broken lock, damaged door frame or smashed window must be secured before you sleep there. Call a 24-hour locksmith. Do not leave an unprotected entry point overnight.
Lodge the claim as soon as possible with the police event number. Keep all receipts for emergency repairs — these are usually covered separately from your main claim.
Community awareness is a practical deterrent. Neighbours who know what happened will watch more carefully. A neighbourhood watch group is worth joining if one exists.
The most important change you can make is to add something that signals the property is now occupied and has been secured. A motion-activated barking alarm is one of the most effective low-cost deterrents: it makes the property sound like someone is home and reacts to approach before entry.
Feeling unsettled after a break-in is a normal response. Knowing you have taken practical steps helps. Talk to someone if anxiety persists — Beyond Blue and Lifeline offer free support.
After a break-in, the most useful security change is not necessarily a new lock — it is adding a layer that tells anyone approaching that the property now feels different. Sound is the most immediate, most believable signal.
| Concern after break-in | Common mistake | More effective approach |
|---|---|---|
| Risk of repeat entry | Only replacing the lock that was broken | Adding a motion-triggered deterrent that reacts before entry |
| "Empty" appearance | Relying on lights on a timer | Adding a sound layer (barking) that no timer can replicate |
| Feeling safe at home | Nothing — hoping it doesn't happen again | Knowing there is an audible response if someone approaches |
| Rental or leased property | Waiting for landlord to act | Portable, no-install deterrent placed at entry points |
K9-Alert is a portable motion-activated barking alarm that works without Wi-Fi, an app or a monthly fee. Place the sensor at any entry point. When motion is detected, the receiver triggers realistic dog barking — immediately signalling that someone is home.
The most common entry points after a break-in. Place the sensor to cover the approach.
Often overlooked after the main entry is repaired. A second sensor can cover these.
Frequently targeted in the same incident or a follow-up. Extend deterrence to detached structures.
Research shows previous victims face a significantly higher risk of repeat victimisation, often within weeks. Offenders know the layout, know what is valuable and know the weaknesses. Making visible and audible changes to your security posture is the best deterrent.
Immediately — before the next night if possible. The period right after a break-in, before new locks are installed and replacements arrive, is the highest-risk window for repeat incidents.
Adding something that makes the property sound and feel occupied: a motion-triggered barking alarm, good exterior lighting and clear sight lines. Locks are necessary but they do not deter approach the way sound does.
Yes. You need a police event number for your insurance claim, and reporting helps police identify patterns in your area. Call 131 444 (non-emergency) or visit your local station.
