TL;DR: ABS counted 217,500 Australian households with an attempted break-in in 2024-25. Back door security in Australia starts with a working lock and frame, then adds a clear rear approach, light and local sound before someone reaches the handle.
It is after dinner. The front porch is lit, but the laundry door sits behind the bins and the side path is quiet. The safest plan is not a camera clip tomorrow. It is making the rear entry harder to approach, harder to open and louder before contact.
Why does the back door deserve separate security?
ABS reported 196,600 Australian households with a break-in and 217,500 with an attempted break-in in 2024-25 (ABS, 2026). The back door deserves separate security because it often combines a quieter approach, weaker visibility and direct access to kitchens, laundries or garage internals.
A front entry is meant to be seen. A back door is often private by design. It may sit behind a side gate, a fence, a carport, a deck or a row of bins where a person can pause without passing the main street-facing entry.
Victoria Police advises households to lock doors, windows, gates, sheds, pet doors, skylights and access points, remove hidden spare keys and make the home harder to enter without being seen (Victoria Police, 2026). Back-door security is where those instructions meet.
Which rear entry should you secure first?
Queensland Police says good home security should help an offender be seen, make entry difficult and make leaving with property difficult (QPS, 2026). Secure the rear entry that gives the quietest path to people, keys, tools or the internal garage before improving lower-risk doors.
Walk the outside in daylight. Mark every door that is not the main front door: laundry, kitchen, garage side door, patio hinge door, deck door, granny-flat entry, storage-room door and any internal garage door that leads into the house.
Prioritise the door that combines cover and reward. A laundry door behind a side gate may be more urgent than a visible patio door under a neighbour-facing light. A garage side door near remotes, tools or bikes may be more urgent than a bedroom door that faces open lawn.
If the route starts at a gate, use the side gate security guide. If the rear entry is a slider, pair this page with the sliding door security guide. If the weak opening is beside the door, use the window security Australia guide.
What should you check on the back door tonight?
AIC research found three-quarters of surveyed burglars took less than five minutes to enter a property, and 66.2% typically entered through unlocked doors or windows (AIC, 2014). Tonight's back-door check should find the simple failures: latch, deadlock, strike, key storage, light and rear-path cover.
| Check | Do this | Why it helps | Do not rely on |
|---|---|---|---|
| Latch | Close the door slowly, then pull it from outside. | You find doors that look shut but have not caught. | A door that only latches when slammed. |
| Deadlock | Lock it and confirm the bolt throws fully into the frame. | The door becomes a barrier, not only a privacy latch. | A strong cylinder beside a cracked strike plate. |
| Keys | Move keys, garage remotes and handbags away from rear glass. | The door stops advertising a quick reward. | A blind that hides nothing when lights are on. |
| Approach | Move bins, chairs, ladders and tools away from the path. | The rear route becomes harder to use quietly. | Assuming a fence is enough while climb aids sit beside it. |
| Light | Check whether the back step and lock side are actually lit. | You reduce hidden time at the handle. | A patio light that illuminates the ceiling only. |
Do the check from outside as well as inside. Stand where a stranger would stand and look for the lock, hinge side, side glass, nearest window, bins, tools and shadows. Back-door risk is often obvious from that position and invisible from the hallway.
How do locks, screens and visibility work together?
Victoria Police recommends deadlocks on external doors and windows, a peephole in the front door and security screen doors where suitable, while QPS recommends solid external doors with quality locks and security screens installed to Australian Standards (Victoria Police, 2026; QPS, 2026). For a back door, those layers should work as one system.
Start with the door and frame. A hollow, swollen or badly aligned door can make good hardware perform badly. If the strike screws are short, the frame is split or the door does not close cleanly, fix that before buying electronics.
Then check the screen or barrier door. A flyscreen helps airflow. A security screen is different: it depends on the mesh, frame, lock, hinge side, standard, installation and condition. Treat the label and paperwork as part of the decision, especially if you are paying for an upgrade.
Visibility matters because a strong lock still leaves a person time to work if the rear step is hidden. Trim plants, move tall pots and keep stored items away from the door. The back door should not feel like a private alcove for someone who is not meant to be there.
What can renters do without drilling?
Consumer Affairs Victoria says renters can install some removable safety devices without permission when they are not hardwired, are removable and do not affect neighbours' privacy (Consumer Affairs Victoria, 2026). Renters should separate repairs, permission requests and portable deterrents instead of changing a back door informally.
If the rear door does not latch, the lock fails, the handle is loose or the frame is damaged, report it in writing as a repair. Include photos and explain where the door leads: laundry, garage, courtyard, side path or shared rear access.
Use reversible steps first. Keep the door locked, stop propping it open, move keys and bags away from rear glass, clear bins from the fence line, and use portable lights or sound where allowed. Avoid drilling into apartment entry doors, fire doors, heritage doors or common-property surfaces without approval.
For a complete rental setup, read the no-drill renter security guide. If the rear entry is in an apartment, also check the apartment security renter guide for strata, balcony and corridor privacy issues.
Where should lights, cameras and barking sound go?
In the AIC offender study, 61.4% named a dog as a deterrent, 49.1% named working alarm systems and 22.8% named sensor lights (AIC, 2014). Put those cues at the rear approach, not only on the door, so the person is interrupted before reaching the handle.
A light should cover the path to the door, the lock side and the step. If it turns on only after someone is already under the patio roof with a hand on the handle, it still helps visibility but is late as a deterrent.
A camera helps with evidence, repeat trespass and package or side-access disputes. It should not be your only back-door measure because footage does not strengthen the door or make the first approach uncomfortable. For privacy-conscious homes, read the home security without cameras guide.
Sound works best from inside. A barking cue, alarm tone or other local alert should make the home feel occupied while the person is still outside. That is different from a siren that starts only after the door is opened.
How do you secure garage and laundry back-door routes?
Tasmania Police advises quality door and window locks, sensor-activated lights and checking that sliding doors or windows cannot be lifted from their tracks (Tasmania Police, 2026). Laundry and garage-side doors need this practical treatment because they often connect storage, tools, keys and the house interior.
The garage route matters because a person may not need to force the main house door first. They may look for remotes, tools, bicycles, car keys or the internal garage door. Keep the internal garage door locked, store remotes out of sight and use the garage security checklist for the roller door and manual release.
The laundry route matters because it is often at the side or rear of the house and may have glass, pet doors, old locks or low attention. Lock the door, check nearby windows, remove keys from hooks and keep the area lit enough that a person cannot stand unseen.
If a side path leads to tools, bikes or a shed before it reaches the laundry, secure the path first. The shed tool theft prevention guide covers that storage risk in more detail.
Common questions
What is the best way to secure a back door?
Start with the door, lock, frame and approach before adding electronics. A secure back door has a working deadlock, strong strike, clear rear path, visible light and an audible response that starts before someone reaches the handle.
Is a laundry door a security risk?
Yes, it can be. Laundry doors often sit behind side gates, garages or dark service paths, so they may be less visible than the front entry. Treat the laundry door as an external entry door and secure it with the same care.
Can renters improve back door security without drilling?
Renters can improve routines, key storage, lighting where allowed and portable motion sound inside their own space. Get written permission before changing locks, screens, frames, outdoor wiring or anything that affects neighbours, common property or the building.
Where should a barking dog alarm go for a back door?
Place the wireless motion sensor where the rear approach begins, such as a covered patio, side path, garage-to-laundry route or back step. Keep the receiver indoors so the barking sounds like it comes from the home before entry.
