Using Public Wi-Fi Safely in Australia: What You Need to Know
From airports and cafés to shopping centres and public libraries, free Wi-Fi is everywhere. It’s convenient and saves your mobile data—but is it safe? Unfortunately, unsecured public Wi-Fi networks can pose serious security risks. Cybercriminals often target these hotspots to intercept your data, steal your passwords, or even access your private information. Here’s what every Aussie should know about using public Wi-Fi safely.

Why Public Wi-Fi Can Be Dangerous

When you connect to an unsecured Wi-Fi network, especially one without a password or encryption, you’re sharing that network with everyone else nearby. A hacker using special software can:

  • See what websites you're visiting

  • Intercept data you send (like login details)

  • Install malware or viruses on your device

  • Redirect you to fake versions of legitimate websites

This is especially dangerous if you're checking your email, online banking, or social media while on public Wi-Fi.


Real-World Australian Example

In 2022, the Australian Cyber Security Centre (ACSC) warned travellers to avoid logging into sensitive accounts on airport or hotel Wi-Fi networks due to an increase in data interception incidents.

Public networks in cafés, shopping centres and regional train stations have also been used by scammers to steal login details from unsuspecting users.


How to Stay Safe on Public Wi-Fi

1. Use a VPN (Virtual Private Network)

A VPN encrypts your internet traffic, even on a public network. It acts like a secure tunnel that hides your activity from others on the same Wi-Fi.

Popular and reputable VPN services include:

These are easy to install and use on phones, tablets and laptops.

2. Use Your Mobile Hotspot Instead

When in doubt, it’s safer to use your phone’s mobile data as a personal hotspot. Your 4G or 5G connection is more secure than most public Wi-Fi networks.

Just keep an eye on your data allowance, especially in rural areas where mobile coverage may be limited.

3. Avoid Sensitive Tasks

Never do online banking, access Medicare, or log into sensitive accounts when connected to public Wi-Fi—unless you’re using a VPN.

Stick to general browsing or reading the news if you're on an unsecured network.

4. Turn Off Auto-Connect

Many devices automatically reconnect to open Wi-Fi networks. Turn off this setting so you’re not unknowingly connecting to risky networks in the background.

5. Use HTTPS Websites Only

When browsing, look for "https://" in the website address. This means the site uses encryption. Most modern browsers also show a padlock icon in the address bar—stick with those.


Australian Resources for Cyber Safety

If you’ve accidentally shared information on an unsecured network, don’t panic—but take action:

  • Change passwords immediately

  • Enable multifactor authentication

  • Monitor accounts for unusual activity
