Brisbane's cybersecurity scene heats up as startups push for smarter defences

Brisbane’s cybersecurity startups are pivoting hard this winter, chasing contracts in automated threat detection as a wave of local councils and SMEs struggle to fill security roles. Six months after the Queensland government spent $12 million on a regional cyber resilience hub, housed at the Brisbane Innovation Centre on St Lucia, a handful of early-stage firms are now shipping AI-driven tools designed to patch vulnerabilities without human oversight.

The shift matters because ransomware attacks in Queensland jumped 30 percent year-on-year, according to the state’s Cyber Security Unit’s latest annual report. Small and medium businesses, which employ more than half of the city’s private-sector workers, remain the most exposed. Many cannot afford dedicated infosec staff.

Startups such as Brisbane-based Bulwark Intelligence and PhishZero, both alums of the River City Labs accelerator in Fortitude Valley, have raised combined seed rounds of $2.8 million since March. Bulwark’s product, a software agent that mimics a security analyst by scanning internal traffic for lateral movement, went live with two undisclosed Queensland councils in June. PhishZero, meanwhile, contracts with a Rockhampton accounting firm and a string of Sunshine Coast retailers.

Boot camps and boardrooms

The talent pipeline remains the industry’s biggest bottleneck. The University of Queensland’s Cyber Security Research Centre graduated 47 students in the 2025 academic year, but fewer than a third stayed in Brisbane. Most took roles in Sydney or Melbourne where starting salaries top $130,000, a premium few local firms can match.

Coder Academy Brisbane, which runs a six-month cyber-security boot camp out of its Turbot Street campus, told The Daily Brisbane its July cohort is full, with 34 students enrolled. That is the highest intake since the course launched in 2022. The academy’s program manager attributes the surge to the Queensland government’s free-skills subsidy, introduced last April, which covers tuition for residents who earn under $80,000.

The picture is not all rosy. A July survey by the Brisbane Chamber of Commerce found that 42 percent of member businesses still use generic passwords for admin accounts, and 18 percent have no documented incident-response plan. Those numbers have barely budged in two years.

What’s next for the local scene

The next 90 days will test whether the startup momentum translates into revenue. Bulwark Intelligence plans to close a Series A round by October; PhishZero is rolling out a free self-assessment tool aimed at sole traders in the Brisbane CBD. The Queensland Cyber Security Council, based in the old State Library annexe on William Street, is hosting its annual industry breakfast on 3 August, where the state’s chief information security officer is expected to outline new procurement rules favouring local vendors.

For now, the advice from local practitioners is straightforward: enable multifactor authentication everywhere, segment your network, and treat every vendor email as suspect until proven otherwise. No startup can patch the human factor, but a few are getting close.
