Cybersecurity for small business in Australia is no longer a “nice to have”, it’s essential to protect your income, operations and customer trust. The good news? You don’t need to be a tech expert or have a massive budget to get the basics right.
This practical guide covers the key cyber risks facing small businesses, simple steps to reduce your exposure, legal obligations to be aware of, and where to find free or low-cost help.
Why does cybersecurity for small business matter?
Even small businesses are prime targets for cyber attacks like phishing and ransomware, which can cause financial losses averaging $46,000 per incident and in some cases serious reputational damage.
Cybersecurity for small business is no longer optional. In Australia, a cybercrime is reported about every six minutes (ACSC, 2024), and over half of these impact small businesses. In Queensland alone, 15% of businesses reported a cyber attack in the past year (DESBT, 2024).
Whether you run a transport business in Mt. Isa, are a property developer on Gold Coast, a manufacturer in Brisbane, run a building and construction business on the Sunshine Coast or are an online entrepreneur, you’re exposed to threats like ransomware, phishing scams, hacked business accounts, and fraudulent invoices.
What’s at stake?
Financial losses — average cost per cyber incident for small businesses is $46,000 (Queensland Gov, 2024)
Business interruption — ransomware or hacked systems can halt operations
Customer trust — data breaches erode brand reputation
Legal obligations — under the Privacy Act and Cyber Security Act 2024
What are the most common cyber threats to Australian small businesses?
Phishing scams, ransomware, and business email compromise are the most common and damaging cyber threats for small businesses.
Understanding these risks is vital when discussing cybersecurity for small business. Here’s what to watch out for:
1. Phishing and Scam Emails
Fake emails or texts that impersonate trusted sources (like suppliers, banks or the Australian Tax Office (ATO). They try to trick staff into revealing passwords or transferring money.
2. Business Email Compromise (BEC)
Hackers impersonate company directors or suppliers to reroute payments to their own accounts. One Queensland construction firm lost over $150k this way.
3. Ransomware
Malicious software that locks up your files, as a result, you pay a ransom. Even paying doesn’t guarantee recovery.
4. Social Media and Account Hijacking
Hackers take control of your business’s Instagram, Facebook, LinkedIn or other social media platform and demand money to return it, and worst, scam your customers while impersonating you.
5. Malware and Fake Invoices
Malware can infect your systems through dodgy attachments or outdated software. Fake invoice scams are especially common in construction and property.
How can small businesses improve cybersecurity without breaking the bank?
Focus on a few essential habits: multi-factor authentication, backups, software updates, and scam awareness.
When it comes to cybersecurity for small business, practical low-cost steps go a long way.
11 Smart Cyber Habits for Everyday Protection
Enable multi-factor authentication (MFA) on all email, banking, cloud accounts, social media accounts and all other business (and even personal) accounts. We know at times have multi-factor authentication can be a pain but losing money or your data to a hacker is even more stressful.
Use strong, unique passwords or a secure password manager. Avoid using personal information, predictable phrases, or simple sequences like ‘123456’. A strong password should be at least 12 characters and include a mix of uppercase and lowercase letters, numbers, and symbols. Better yet, create a passphrase using four or more unrelated words (e.g. ‘river-orange-moon-train’) add in numbers and symbols.
Update software and apps regularly to patch vulnerabilities.
Back up your data — follow the 3-2-1 rule (3 copies, 2 types, 1 offsite).
Install antivirus/security software on all devices including mobile phones.
Train your staff to recognise scams and verify payment requests. This includes checking the email address the email has come from. Scam are becoming much more professional, if in doubt, call the business or person involved to confirm if the email was actually from them.
Secure your Wi-Fi and devices — change default passwords, isolate guest networks.
Limit admin access — staff should only access what they need.
Have a response plan — know who to call, what to shut down, and how to notify customers.
Consider cyber insurance — especially if you hold sensitive customer data.
Remove access when staff members leave – it is important to immediately remove access to emails, software(s), social media etc when a staff member leaves.

What cybersecurity laws affect small businesses in Australia?
Small businesses must comply with federal privacy rules and may be subject to new ransomware reporting laws under the Cyber Security Act 2024.
When thinking about cybersecurity for small business, legal compliance is part of the puzzle:
Initially applies to certain sectors or turnover levels
Must report ransomware payments within 72 hours
Note: These obligations may expand, in either case, it’s smart to prepare early.
