The Best Mailboxes Anti-Theft Solutions in Australia
The Rising Issue of Mail Theft
In today's Sydney and Melbourne, Australia, mail theft has become a serious issue. From personal letters to important documents and packages, thieves are becoming increasingly cunning in their attempts to steal mail.
A significant number of mailboxes still use standard cam locks, which operate with universal mailbox keys. These keys were originally intended for exclusive use by postal workers, but they have unfortunately fallen into the hands of mail thieves.
Both standard and GEM cam locks are vulnerable to unauthorized access, compromising the safety of mailboxes and their contents.
Mail theft can lead to serious consequences including:
- Identity theft
- Financial fraud
- Stolen personal information
- Loss of important documents
- Unauthorized building access when access cards are shared through mailboxes

How Thieves Access Your Mailbox
Universal Keys
Thieves use universal mailbox keys that can open standard cam locks. These keys are readily available and can open multiple mailboxes.
Force and Manipulation
Standard mailbox locks can be easily forced open using simple tools like screwdrivers or manipulated with basic lock-picking techniques.
GEM Lock Vulnerability
GEM cam locks with small, round-shaped keys are just as vulnerable, with universal keys easily available to open these locks.

How Our CAM LOCK PRO Works


The base of Prox Access PRO locking system consists of a row of eight rotary discs rotating in nine special inserts, called rotating discs spacers. This new patented system is operated by a symmetrical key that can be turned only once it is completely inserted in the cylinder which prevents the cylinder from being damaged.
The combinatorics of this locking system can be increased by individual key profiles. This ensures a high number of locking combinations, which ultimately brings the uniqueness of the key. Each key profile is characterized by the cross section of the key profile in a section that passes through the controller and by the cross section in the key end part which passes through the stopper.
