Every business in Australia today depends on technology to operate, grow and compete. That makes cyber security not just an IT concern, but a core business issue. Whether you run a small to medium-sized business in Perth, or anywhere across Australia, the risks are real, evolving and increasingly costly. Recent data and media reports make one thing clear: ignoring cyber security is no longer an option.
Here’s why.
Cyber Security Threats are Growing and Sophisticated
The Australian Cyber Security Centre’s (ACSC) Annual Cyber Threat Report highlights that cyber threats continue to rise. In the 2024 – 25 reporting period, the ACSC responded to over 1,200 cyber security incidents, an 11% increase from the prior year and issued more than 1,700 notifications of potentially malicious activity to Australian organisations, emphasising persistent and adaptive threats.
This is not just large organisations. Small and medium businesses are increasingly in attackers’ sights because they often have valuable data but lack robust defences.
Scams and Email Attacks Are Costing Australian Businesses Millions
Cyber scams and business email compromise (BEC) are on the rise. No one is immune.
In late 2025, Microsoft took down an AI-enabled scam network that had compromised over 191,000 Microsoft email accounts globally, including roughly 3,600 in Australia. These scams have contributed to Australians losing hundreds of millions of dollars in just the first nine months of 2025.
In a separate high-profile case, Noosa Council in Queensland lost millions in ratepayer funds to a sophisticated email scam that used social engineering tactics to manipulate payment processes.
Even government agencies have fallen victim to fraud resulting from forged emails and impersonation, with one case involving a Northern Territory agency allegedly losing $3.5 million before most funds were recovered.
These events show that any organisation with online systems, email traffic and financial transactions is at risk. The cost is not just financial, but reputational and operational too.
Small and Medium Businesses Are Prime Targets
While the headlines often focus on large breaches, smaller businesses are also at risk. Ransomware and other attacks are increasingly targeting SME environments because attackers can exploit gaps in security measures.
Reports indicate that more than two-thirds of Australian organisations have experienced a ransomware attack in recent years, and the majority of those hit opted to pay the ransom.
Threat actors are also evolving. Phishing attacks, business email compromise and AI-powered scams now target finance teams and executives with highly convincing fake invoices and payment requests. One industry analysis found that one in three successful breaches began with a business email compromise, with median losses of around $64,000 for affected organisations.
Cybercrime Is Not Limited to External Threats
Cyber Security incidents include not just hacks and malware, but also human error and internal vulnerabilities. The Notifiable Data Breaches Scheme data shows that malicious or criminal attacks accounted for 69% of data breach notifications, with the majority involving cyber security incidents.
This reinforces two important truths:
- Cyber security must be part of everyday business operations
- Preparation and prevention reduce exposure and impact
It is not enough to rely on firewalls or antivirus software alone. Businesses need a holistic view of their digital risk across people, technology and processes.
The Hidden Costs of Cyber Incidents
The costs of a cyber security incident extend beyond the immediate financial loss.
- Operational disruption. A breach can interrupt workflows, customer service systems and supply chains.
- Reputational impact. Clients and partners may lose confidence in an organisation’s ability to protect data.
- Legal and compliance consequences. Data breaches may trigger regulatory reporting obligations and penalties.
- Long-term recovery costs. Restoring data, systems and trust often incurs significant expense.
Australian government reporting underscores this trend, with cybercrime causing increasing burdens on businesses and individuals alike. One report noted that calls to the ACSC Cyber Security Hotline were averaging 100 per day in the latest reporting period, up from 90 per day previously.
The Take-home Message for Your Business
Cyber security risk is business risk.
It affects your finances, your customers, your reputation and your ability to deliver services. It is no longer something that small and medium businesses can treat as an afterthought or simply hope it will not happen to them.
You cannot afford to wait until after an incident to take action.
