A secure phone or secure cell phone in Australia reduces the everyday risks of scams, malicious apps, loss or theft, and data breaches. No phone is unhackable, but the strongest practical option for most people is a new Australian-stock Pixel running GrapheneOS. It is not a stock Android phone, an iPhone, or a device that reports to Google.
Quick answer
These overlap but aren’t the same. GrapheneOS on a Pixel addresses all three in practical ways.
Most risks are ordinary rather than high-end targeted spyware.
Australians reported $2.18 billion in scam losses across 481,523 reports in 2025 (National Anti-Scam Centre). The OAIC received 1,205 notifiable data breach notifications in 2025 (see What to Do After a Data Breach). Nearly half of Australian computer users experienced some form of cybercrime in the previous 12 months. Common issues include phishing and scam apps, lost or stolen phones, public Wi-Fi, and data that ends up in breaches elsewhere.
A secure phone does not stop every risk, but it narrows the ones that matter day to day.
GrapheneOS is a privacy and security focused mobile operating system based on Android. It removes Google services and tracking by default while keeping Android app compatibility. Apps are more strongly sandboxed, and optional sandboxed Google Play can be added in a profile that needs it, without special system privileges.
For how GrapheneOS compares with other de-Googled systems, see GrapheneOS vs others.
Google Pixel phones include a dedicated security chip and support verified boot. After GrapheneOS is installed the bootloader can be locked again, which helps protect the phone from being modified. Pixel 8 and later models also include hardware memory tagging, which makes certain types of attacks harder. Newer Pixels receive longer guaranteed update support from Google as well.
These are the controls that matter day to day, and feature in our Privacy Phones. For more detail, see kill switches and isolation features.
GrapheneOS currently has official production support for the Pixel 6 through Pixel 10 series. Pixel 8 and later models are recommended for longer support and hardware memory tagging. In March 2026, GrapheneOS announced a long-term partnership with Motorola for future devices that meet its standards and will receive official support.
In October 2026 a researcher disclosed the “SMS of Death”: one hidden text message can crash an Android phone’s calling service and drop calls, including emergency calls, with nothing showing in Messages. GrapheneOS says it shipped the fix in July 2026, months before the public disclosure, and that Google rates the bug critical (CVE-2026-58882) in its November 2026 Android security bulletin.
An iPhone with Lockdown Mode and Advanced Data Protection enabled is stronger than a default iPhone. It still includes Apple services and accounts by design. GrapheneOS removes Google services by default, uses stronger sandboxing, and adds specific controls such as auto-reboot, USB-C port control and a duress PIN. Both approaches can be secure. The differences are in default tracking, account requirements, and the security features available.
These steps apply to every phone, not just a secure one, and align with guidance from cyber.gov.au:
Separate profiles let you keep work apps and data isolated from personal use. This is useful for small-business owners and professionals who want clearer separation without carrying two phones. Each profile has its own apps, data and encryption keys, and you can switch between them in seconds. GrapheneOS supports multiple profiles with independent settings and permissions.
Most Android apps, including major Australian bank apps, work on GrapheneOS. Some require optional sandboxed Google Play in the profile that needs them. Australian mobile networks (Telstra, Optus, Vodafone) function normally and you can keep your existing number. Specific app behaviour can vary; contact us for a particular bank or app.
An encrypted phone stores its data in a form that cannot be read without the correct credentials. Modern Pixels and GrapheneOS provide encryption at rest by default. This protects the contents if the phone is lost, stolen or examined while locked and powered off (or after auto-reboot). It does not stop all attacks while the phone is unlocked and in daily use.
For a secure phone you carry all day that stores your sensitive personal data, these details matter. For a fuller comparison, see what to check when comparing privacy phones in Australia.
A secure phone reduces everyday risks such as scams, malicious apps, loss or theft, and data breaches. It combines a hardened operating system, strong hardware, and simple controls you will actually use. No phone is unhackable. We recommend a new Australian Pixel running GrapheneOS, already configured, with a two-year Australian warranty and local support.
An iPhone with Lockdown Mode and Advanced Data Protection turned on is stronger than a default iPhone. It still includes Apple services and accounts by design. GrapheneOS removes Google services by default and adds controls such as auto-reboot, USB-C port control, a duress PIN, and separate profiles. Both can be secure for different people.
Yes. It is free open-source software that you install and use on a phone you own. It works on Telstra, Optus and Vodafone, and you keep your existing number.
No. Australian law requires telecommunications providers to retain certain metadata for two years. A secure phone reduces what apps and the operating system collect, but it does not change the legal obligations on your telco.
A refurbished phone can carry unknown history or weaker update support. We recommend new Australian-stock Pixels with a two-year warranty.
Most major Australian bank apps work with optional sandboxed Google Play in the profile that needs them. Google Pay does not.
Check that it is new Australian stock with a two-year warranty, runs GrapheneOS with a locked bootloader, arrives professionally configured, and includes a Quick Start Guide and User Manual. Many “private phones” and “privacy devices” sold in Australia are refurbished, grey imports, or unfinished setups with no real support.
A secure phone is less about marketing claims and more about the combination of hardware, a hardened operating system, level of professional configuration, and controls you’ll use day to day.
A new Australian-Pixel running GrapheneOS, supplied ready to use with 2y Australian warranty and support, is the practical choice for most people.
The phone itself is only part of the setup. Good habits, careful app choices, and basic steps such as keeping software updated are also required to keep a phone secure.
