Security Grilles for Newcastle Windows: Keeping Intruders Out Without Trapping You In

Why a grille that keeps a child in can keep you in

Most grille conversations start with one question: will it keep someone out? The better first question is whether it will let you out.

Two sources fit together in a way neither says outright. What follows is our reading of them.

In a NSW strata building, an openable window needs a child-safety lock if its lowest part is within 1.7 m of the inside floor and that floor is 2 m or more above the ground outside. Security screens such as bars or grills can be used instead of locks, as long as any gaps are under 12.5 cm. Separately, Fire and Rescue NSW wants, where best possible, two means of escape from every room.

Nobody climbs through a 12.5 cm gap. So a fixed grille built to keep a toddler safe also takes that window off the list of ways out. In a bedroom with one door and one window, that leaves a single exit. In a fire, that exit may be the hallway the smoke is coming down.

That doesn't make grilles a bad idea. It means two things matter more than the steel: which windows you bar, and how those grilles open. Our view at Newcastle Shutters is that you should settle which windows must stay an exit before anyone talks about patterns or colours.

What Fire and Rescue NSW asked for after the Wiley Park fire

In August, ABC News reported on a fatal granny-flat fire at Wiley Park in Sydney on 29 July 2026. Fire and Rescue NSW (FRNSW) said the only exit was blocked and the building's four windows were secured with iron bars. The ABC also reported that the cause was still under investigation when it published, and does not say whether the bars played a part.

What FRNSW said afterwards applies to any Hunter home with bars on its windows. Acting Chief Superintendent Scott Donohoe urged everyone to find that balance between home security and home fire safety, whether it be bars on windows, [or] deadlocked doors and windows. FRNSW says it has seen residents struggle to get out of fires because of security measures. That is why it calls a fire escape plan "critical".

The building code asks for less than FRNSW advises. The ABC reports that the National Construction Code requires houses and granny flats (Class 1a) to have at least one exit from each storey, while FRNSW says two options per room is best. Meeting the code's minimum is not the same as having a plan.

If you're unsure about your own home, anyone can ask FRNSW for a free home fire safety visit (checked November 2026). The visit covers advice, a smoke alarm check, and a free alarm if you have none.

Who has a say: owner, renter or strata

If you own a house and live in it, the decision is mostly yours, with two checks. First, if the home is heritage-listed or in a conservation area, ask City of Newcastle whether anything external needs approval. Our heritage homes page covers the inside-the-glass side of older homes. Second, plan the exits before the grilles go on.

If you rent, two different rules apply.

The first is about the landlord's duty. Your landlord must provide and maintain locks and security devices so the property is "reasonably secure", and what that means varies with the situation. If you think your home falls short, ask the landlord first. After that, you can complain to NSW Fair Trading or apply to the Tribunal.

The second is about adding anything yourself. A landlord or tenant can change or add locks or security devices only with the other party's consent or on reasonable grounds. Doing otherwise is an offence and a breach of the tenancy agreement.

NSW does have a list of minor changes a landlord cannot refuse. It includes:

• fly screens
• window safety devices for child safety
• shatter-resistant film that doesn't penetrate or permanently modify a surface.

Security grilles and bars are not on that list. The minor-changes provisions also don't apply to heritage properties, and strata schemes carry their own restrictions. So for a renter, a grille starts as a conversation with the landlord, and permission needs to be in writing.

If bars already on your rental worry you, FRNSW's advice, as reported, is that tenants should speak to their landlord.

If you own in a strata scheme, the owners corporation has a role, and NSW has a specific window-safety rule. The next section covers it.

Where grilles fit in the NSW strata window-safety rule

These are strata rules. They don't cover freestanding houses, but the numbers make a useful yardstick for anyone thinking about child falls.

Under NSW Fair Trading's guidance, a strata window needs a safety lock if its lowest part is within 1.7 m of the inside floor and that floor is 2 m or more above the ground outside. The lock must:

• stop the window opening more than 12.5 cm
• be childproof
• resist force equal to 25 kg.

Fixed windows need no lock.

Bars or grilles can do the lock's job if any gaps are under 12.5 cm. Flyscreens count only if they resist very strong outward pressure.

In a strata scheme, the owners corporation must pay to install and repair window locks unless the by-laws say otherwise, so the cost doesn't fall on the individual owner by default.

A grille that meets the gap rule is not an escape route, by design. On a third-floor apartment window that may be fine, because that window was never your way out. A ground-floor bedroom is a different call. Either way, raise any grille with the owners corporation before it goes on.

Grille, shutter or screen: which suits which window

Start with perspective. NSW's latest recorded crime figures show break and enter dwelling stable statewide and stable in regional NSW over the two years to June 2026. Our break and enter guide looks at what the numbers say and where windows fit. A grille is one layer of security, not a guarantee, and nothing here promises it will stop a break-in.

A grille earns its place on a window that is easy to reach from outside and that nobody needs as an exit. Laundries, side bathrooms and windows onto a laneway are typical candidates. A bedroom window is the one to think hardest about. If it gets a grille, the grille should open from inside, quickly, by anyone who sleeps in that room.

Shutters do a different job. They sit inside the glass and handle privacy, light and heat. They are not a security device, so don't buy them as one. If your real aim is privacy on a street-facing window, plantation shutters may answer it without barring anything. Our plain-English primer explains how they work.

When the worry is a child falling rather than a stranger getting in, a window safety device or a restricting lock may do the work without turning an exit window into a wall.

What to settle before anyone quotes for a grille

Work through this list before you get a quote:

• Which bedroom windows must stay an exit? FRNSW's aim is two means of escape from every room, where best possible. Mark those windows first.
• How does each grille on an exit window open? It should open from inside, without tools and without a hunt for anything.
• Where are the keys? Somewhere every person in the house can reach, including in the dark and including older children.
• Is there a smoke alarm in the hallway outside the bedrooms? It should be working and tested.
• Do you have an escape plan? Write it down and walk it through with the household. FRNSW calls it critical.
• What is the property's status?
  • Heritage: ask City of Newcastle whether anything external needs approval.
  • Strata: go to the owners corporation.
  • Rental: you need the landlord's consent, and adding a security device without it is an offence.

Your next step

If you're weighing a grille against shutters for a particular window, start with the list above, then talk it through with Newcastle Shutters. Bring your marked-up window list, tell us which rooms you sleep in, and ask for a measure and quote on the windows where privacy, light or heat is the real problem. Leave the exit windows open for a conversation, not a default.
