NO HOLDS
BARRED...EVER.

The COSAC APAC 2026 Call for Papers is open! Welcome to COSAC - Information Security conferencing the way it should be! Join us in Melbourne for 3 days of innovative & participative information security value.

24th to 26th February 2026

An Information Security Conference Like no Other

Free thinkers are invited to attend COSAC APAC 2026.

If you have ideas, are open to new ideas, or love having your ideas challenged then we want you at COSAC APAC 2026.

We’ve stripped away all the nonsense that leads to status-quo thinking – so you’ll find no vendor displays, sales pitches, or ‘best-practice’ thinking.

Instead, you’ll be among an international community of big thinkers who check their egos, job titles and company names at the door.

If that excites you, view our delegate registration packages including evening meals & receptions to maximise your collaboration time with the COSAC Community. The Call for Papers is now open…
