Your Cart is Empty
A letterbox might be one of the smaller features of your home, but it is also one of the first things people see when they arrive. Sitting beside the driveway, attached to a fence or mounted near the front entrance, it becomes part of the overall look of your property.
That is why choosing a letterbox deserves a little more thought than simply finding somewhere for the postie to leave the mail.
Australian homes also present their own challenges. A letterbox can spend years exposed to sun, rain, wind and changing temperatures, so good design needs to be backed by suitable materials and practical construction.
For most homeowners searching forletter boxes in Australia, the ideal choice combines appearance, durability, security and everyday convenience.
Why Your Letterbox Matters More Than You Might Think
Think about everything that contributes to the first impression of a home: landscaping, fencing, the driveway, house numbers, exterior lighting and the front door.
Your letterbox sits among these elements.
An old or poorly positioned mailbox can feel disconnected from an otherwise carefully designed exterior. A thoughtfully chosen contemporary letterbox, on the other hand, can complement the architecture and help create a more considered entrance.
This is particularly relevant to modern Australian homes, where clean lines, simple forms and restrained exterior colour palettes are common.
AtArko Furniture, letterboxes are approached as functional design pieces rather than purely utilitarian containers. Arko's range is designed and manufactured in Melbourne, with contemporary options suitable for different Australian homes and architectural styles.
What Should You Look for When Buying a Letterbox in Australia?
There is no single letterbox that suits every property. Before choosing one, consider where it will go, how much mail you normally receive and how the design will relate to your home.
1. Materials Made for Outdoor Conditions
A letterbox spends most of its life outside.
That means its materials and finish are particularly important. Stainless steel and durable powder-coated finishes are practical choices because they can provide the strength and weather resistance required for outdoor installations.
Arko's letterbox collection includes stainless-steel designs with powder-coated finishes, including models available in Colorbond® colour options.
The advantage is practical as well as visual: you can coordinate your letterbox with other exterior elements instead of treating it as an afterthought.
2. Post Mounted or Wall Mounted?
One of the first decisions is how the letterbox will be installed.
A post mounted letterbox works particularly well when the mailbox needs to sit near a driveway, front boundary or entrance. It can become a freestanding architectural feature in its own right.
A wall mounted letterbox may make more sense when space is limited or when there is already a suitable wall or fence close to the delivery point.
Consider accessibility too. Your letterbox needs to be convenient for mail delivery without creating unnecessary obstacles around the entrance to your property.
3. Enough Room for Everyday Mail
A beautiful letterbox is not much use if your mail constantly sticks out of it.
Australia Post recommends that, as a minimum, a letterbox should allow an A4 envelope to lie flat inside. Its guidance identifies 230 mm wide, 330 mm deep and 160 mm high as useful letterbox dimensions, with the delivery slot positioned approximately 900–1200 mm above ground level.
Your own requirements may be greater, particularly if you receive significant quantities of mail, magazines or other regular deliveries.
4. Security
Letters can contain far more than advertising material.
Bills, replacement cards and correspondence containing personal information may all pass through your mailbox, making security worth considering when choosing a new one.
A design with secure mail storage and a lockable access door can help keep correspondence protected until you collect it.
For example, Arko's letterbox designs include lockable access, combining security with a clean contemporary appearance.
Where Should a Letterbox Be Positioned?
Location matters almost as much as the letterbox itself.
Australia Post advises positioning a letterbox where it is clearly visible and accessible, such as at the property boundary, on the fence beside the driveway or in a comparable accessible position. The property number should also be clearly displayed.
Avoid surrounding the delivery point with shrubs, rocks or other obstacles that make access difficult.
Before installing your letterbox, it is therefore worth looking at the entrance from the perspective of both the homeowner and the person delivering your mail.
Can the letterbox be reached easily? Is it obvious which property it belongs to? Will growing plants eventually obstruct it?
Thinking about these questions before installation can save inconvenience later.
Matching a Letterbox to Your Home
The best letterbox does not necessarily need to disappear into the background.
Sometimes contrast works beautifully.
A dark letterbox against a pale fence can create a sharp contemporary detail, while softer colours can complement landscaping and natural materials.
Alternatively, you can coordinate the letterbox with existing exterior finishes.

Choosing one of these elements as a colour reference can help your new letterbox feel connected to the rest of the property.
Arko's Colorbond® letterbox collection provides a particularly useful selection for Australian homes, with colours including Monument, Surfmist, Woodland Grey, Pale Eucalypt, Deep Ocean, Cottage Green and others.
Modern Letterboxes Can Still Be Practical
There is sometimes an assumption that highly designed products sacrifice practicality for appearance.
A good letterbox should do neither.
Consider the Arko Colorbond® Letterbox as an example. It uses powder-coated stainless steel with nylon components, incorporates a lockable hinged door and comes with a galvanised steel post and adjustable mounting plate.
The result is a recognisably functional letterbox presented as a much more considered piece of exterior design.
That balance is important.
After all, you interact with a letterbox regularly. It needs to be straightforward to use, capable of protecting your mail and suitable for its environment. Good looks should complement those qualities rather than replace them.
Australian-Made Letterboxes
There is another consideration for homeowners looking specifically for letter boxes made in Australia: where and how the product is designed.
Arko's letterboxes are designed and manufactured in Melbourne.
Local design is especially relevant for outdoor products because Australian conditions can be demanding. Materials, finishes and construction all need to be considered with outdoor exposure in mind.
Choosing an Australian-made letterbox can also appeal to homeowners who want locally designed products incorporated throughout their renovation or new build.
Letterbox Maintenance
A quality letterbox should not demand constant attention, but occasional maintenance can help preserve its appearance.
Remove dust, dirt, salt deposits and environmental grime before they accumulate. Check moving components occasionally and keep the area around the mailbox clear.
Homes close to the coast may warrant more frequent cleaning because airborne salt can be particularly demanding on exterior materials.
Always follow the manufacturer's care recommendations for the specific materials and finish of your letterbox.
Choosing a Letterbox You'll Still Like Years From Now
Trends come and go quickly. Your letterbox probably won't.
For that reason, it is often worth choosing a design with clean proportions and a colour that relates naturally to the property rather than selecting something simply because it happens to be fashionable.
Ask yourself a simple question:
Will this letterbox still suit the house if we repaint, renovate or change the landscaping?
A well-designed contemporary letterbox should be able to adapt.
Frequently Asked Questions About Letter Boxes in Australia
What size should a letterbox be in Australia?
Australia Post recommends enough internal space for an A4 envelope to lie flat. Its published security guidance suggests dimensions of approximately 230 mm wide, 330 mm deep and 160 mm high as a useful benchmark.
How high should a letterbox be?
Australia Post recommends positioning the letterbox slot approximately 900–1200 mm above ground level.
Where should I put my letterbox?
It should be clearly visible and easily accessible for mail delivery. Common positions include the property boundary or fence beside the driveway. Keep the approach free from obstacles.
Are lockable letterboxes worth it?
A lockable compartment can provide additional protection for personal correspondence and other mail, particularly when you cannot collect your post immediately.
Is a post mounted letterbox better than a wall mounted letterbox?
Neither is automatically better. Post mounted models are useful where the letterbox needs to stand independently near a boundary or driveway. Wall mounted models are a practical solution where an appropriate wall or fence is already available.
What material is best for an outdoor letterbox?
Durable metals such as stainless steel with an appropriate exterior finish are popular choices. Look for construction and finishes intended for outdoor conditions rather than choosing on appearance alone.
Can my letterbox match my Colorbond® exterior colours?
Yes. Choosing complementary colours can connect the mailbox visually with roofing, fencing, garage doors and other exterior finishes. Arko offers several letterboxes in familiar Colorbond® shades.
