About
Outback Overflow is a free online jeopardy-style CTF built for high schoolers across Australia. Run by the High School Cybersecurity Community, it's designed to be a stepping stone for students getting into cyber security, whether you've never touched a terminal or you're already popping shells.
Our goal is simple: grow the number of young people in cyber security and give Australian high schoolers a CTF they can call their own.
