High School Cybersecurity Community

We're a student-run group for high schoolers across Australia who are into cybersecurity. Whether you're just getting started or already competing in CTFs, HSCC is a place to learn, build skills, and connect with others who share the same interest.

Outback Overflow CTF

Our first event — a free, online, jeopardy-style capture the flag competition. Open to everyone, with dedicated prizes for high school teams.

Challenges will span web exploitation, cryptography, forensics, reverse engineering, OSINT, and more — ranging from beginner-friendly to advanced. We're building challenges with support from university security societies including UNSW SecSoc.

Get involved

We're looking for challenge authors, sponsors, and anyone who wants to help grow cybersecurity education for young people in Australia. If you're a company, university society, or individual interested in supporting Outback Overflow, reach out — whether that's sponsoring prizes, contributing a challenge, or just spreading the word.
