CTF Event
Outback Overflow
Nov 20–21, 2026
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. Sponsors: BinaryLane (binarylane.com.au) UTS:CSEC (utscyber.org) XYZ (gen.xyz) (if you would like to sponsor please reach out to outreach@hscyber.org or join our discord!) Join our discord to talk to other players! https://discord.gg/xWPndqMCfA
