A Penetration Tester is a cyber security specialist who tests systems for security flaws. Using the same tools as malicious hackers, they probe networks, applications, and IT systems on behalf of organisations. Their work reduces the risk of real breaches.
The role covers a broad scope of technical work. Penetration Testers gather target data, run security scans, and carry out controlled attacks. They write up every finding and deliver clear reports with steps on how to fix each issue.
Most roles need strong networking and OS skills, plus scripting in Python or Bash. Employers look for certifications such as the Offensive Security Certified Professional (OSCP) or Certified Ethical Hacker (CEH). A master’s degree in cyber security helps for senior roles.
Job prospects are excellent. Around 13,300 ICT Security Specialists were employed in Australia in 2025 (Your Career, 2025). Employment is set to grow 14.2% from 2024 to 2029. That is well above the national average (Jobs and Skills Australia, 2025).
