Personal data fuels the modern digital economy, yet many Australians remain unaware of how much information they leak through everyday online activities. Cyber threats range from large-scale data breaches at corporations to targeted phishing attacks that arrive as a seemingly genuine email from a bank or a delivery service. The first layer of defence is understanding what data you are sharing and with whom. Review the privacy settings on social media accounts and restrict the visibility of your birth date, phone number, and address to friends only, or better, to nobody. Regularly audit the apps on your phone, deleting any you no longer use and checking the permissions of those that remain. A torch app has no legitimate need to access your contacts or location, yet many quietly collect and sell such data. Treating personal information as a valuable asset shifts your behaviour from a passive acceptance of terms to an active gatekeeping role.

Passwords remain the gatekeeper to your digital life, yet “123456” and “password” still feature in breach lists. A password manager offers a practical solution, generating and storing complex, unique passwords for every service so you only need to remember one strong master phrase. Choose a master password that is a long, memorable sentence with a few numbers and symbols, something like “Galahs+squabble+in+the+gumtrees!7”. Enable two-factor authentication (2FA) wherever possible, preferably using an authenticator app rather than SMS, because SIM-swapping attacks can intercept text messages. With 2FA active, even if a criminal obtains your password, they cannot access your account without the second factor, which dramatically raises the bar. Revisit your critical accounts – email, banking, superannuation, and government portals like myGov – and ensure they are locked with the strongest available authentication.
Phishing attacks have grown remarkably sophisticated, often mimicking the branding and tone of trusted Australian organisations. They frequently create a sense of urgency: a package awaiting delivery, a tax refund needing immediate action, or a fine that must be paid instantly. A simple rule can protect you: never click on a link in an unsolicited message. Instead, open a browser yourself and manually type the official web address, or call the organisation using a number you already trust, not one provided in the suspicious communication. Hover your mouse over any link to see the true destination URL. Train your household, particularly older relatives who may be less familiar with digital traps, to apply this pause-and-verify approach. Scammers rely on hurried, emotional decisions; a moment of doubt is often enough to avert disaster.
