In the past, an unsecured parcel letterbox was the main type of mailbox we used to get our mail delivered to. Today, rather than physical mail, most of us get our bills and subscriptions digitally. Deliveries to our doors are generally packages and parcels from our online purchasing orders. 

Some of them can fit through the letterbox flat, but many are too large. This results in “Sorry, we missed you” messages notifying us that our item is hidden somewhere in the garden, with a neighbor, or ready for collection the next day. Either that or the package is left sitting on the porch, making it a potential target for thieves.

A parcel letterbox offers a solution to all of these problems. It allows the postman to deposit your mail in a dry, secure location until you arrive home to retrieve it.  

What You Need to Know When Selecting a Parcel Letterbox

How Does a Parcel Letterbox Work?

When shopping for a letterbox in Australia, you’ll come across a range of parcel letterbox models. Although parcel letterboxes can vary in design and color, they all work the same way: they include a large opening flap that allows the post of packages and parcels. The parcel is dropped into a safe hold and will remain there until you unlock the door. Anti-theft features restrict the maximum size of the aperture flat, retaining baffle plates, shelves, and other components in place to prevent anyone from reaching your mail. 

Benefits of a Parcel Letterbox


Deliveries are generally performed during business hours when we are at work. With a parcel letterbox delivery, there is no need to ensure that someone is present to answer the door. It allows your mail to be delivered securely and kept safe until it is convenient for you to retrieve it.

You don’t need to worry, even if you’re going to be out for an extended period. Items can be sent to your smart parcel letterbox many times a day because the mailbox does not need to be emptied after each delivery. As you will be informed as soon as the package is delivered, you can have an idea as to when the box needs to be emptied.

Theft Prevention

The growth of online shopping has also led to an increase in parcel theft. With so many packages and parcels floating around, many of which are left unattended and not so well hidden behind your bins, the unscrupulous have found a way to profit from it.

There is nothing like a parcel delivery box for concealing your packages. It’s safe and durable, and to pry it open, a thief would have to make a lot of noise, which would get the attention of even the most daring among them.

Weather Protection

We never know when a parcel is going to be delivered. This means it might be exposed to the elements for longer than you’ve planned, perhaps causing significant harm to your contents. Due to the possibility of damage, you might not even be able to return the headphones you ordered which weren’t quite what you expected. A parcel letterbox shields your packages from any weather-related damage.

What to Consider When Choosing a Parcel Box

Installation Type

Retailers that sell parcel letterboxes in Australia generally carry different models to meet the needs of different customers. The most common of them include:

  • Through the Wall, Fence, or Gate Parcel Boxes – This style of parcel box is the most popular. It includes a discreet outer flap for deliveries, and the hold is tucked out of sight. It comes in two parts: one for the outside and one for the inside. Finishing the installation of this letterbox with a sealer is required to prevent moisture penetration and keep your mail dry.
  • Free Standing Parcel Boxes – This model is another excellent choice. Fixed to the ground, a free-standing letter box offers the greatest versatility as to where they can be installed. They also have the largest hold capacity, which is good for folks who enjoy shopping online. Internal shelves are a common feature of freestanding parcel boxes. Some of them slope while others rise and lower in response to the opening flap. In both cases, this helps cushion the drop into the hold and adds a layer of protection to limit access.
  • Wall Mounted Parcel Boxes – These mailboxes are usually installed next to the front door or on a porch and come with a basic mounting kit. Although the hold is smaller in this type of parcel box, it still can accommodate a great amount of packs. Certain letterboxes that are mounted on walls have an opening at the top to accommodate larger packages. Mailmen may easily remove the lid and drop the mail inside thanks to this feature.


Goods are delivered in packages of all sizes. Even small items may require a great amount of packaging to be contained properly. If you’re the kind of person who frequently receives packages that are too large to fit through your traditional letterbox and are left on your doorstep, you should consider the size of your letterbox carefully. 

Parcel letterboxes are generally available in three sizes: standard (32×23x18cm), large (41x31x22cm), and extra-large (52x39x32cm). Consider the size and the number of packages you generally receive and choose the letterbox size that better suits them. 

Security Features

This is an important consideration for any kind of parcel box. To keep your items protected from theft and extreme weather conditions, look for models with solid construction, long-lasting materials such as stainless steel or heavy-duty plastic, and secure locks. Some modern mailboxes even include tamper-proof features and electronic access controls for enhanced security.

Weather Resistance

It’s critical to invest in a mailbox that can endure a range of weather conditions. Seek models with rust-resistant coatings and weather-resistant seals to avoid damage from humidity, rain, and sun rays. A weather-resistant mailbox will keep your packages safe and dry even during extreme weather.


Your mailbox contributes to the curb appeal of your home, thus it should be visually appealing. Choose a design that suits your home’s exterior and personal style. There are a variety of options to suit your tastes, ranging from modern and minimalist to classic and elaborate.

The evolution of mail delivery from traditional unsecured parcel letterboxes to modern parcel letterboxes marks a significant step towards enhancing convenience, security, and protection against weather elements.

The shift towards digital communication for bills and subscriptions, coupled with the surge in online shopping, necessitates efficient solutions for parcel deliveries. Parcel letterboxes not only offer a secure and convenient means of receiving packages but also mitigate the risks of theft and weather-related damage.

When selecting a parcel letterbox, considerations such as installation type, size, security features, weather resistance, and design play pivotal roles in ensuring optimal functionality and aesthetic appeal. Embracing these advancements in mail delivery systems not only streamlines the process but also enhances the overall experience of receiving parcels in today’s digital age.
