If your institution wants to advertise Theory jobs to the FOCS 2025 attendees, a form has been set up on our website: focs.computer.org/2025/activit... The spreadsheet collating job openings in TCS will be made available to attendees (and online), to help graduating students and junior researchers.

Update: We have decided not to provide Vegemite jars in the #FOCS2025 swag bag, on the grounds that this may be prohibited under the 1993 Chemical Weapons Convention. You will, however, get tim-tams.

We're still finalizing the conference program, so stay tuned! As a teaser: we heard jetlag is a thing, and mornings are hard—especially after Sunday's workshops and welcome reception. To help with that, Monday morning will feature barista coffee: begin the week with a flat white! ☕

The early registration deadline is November 21, 2025 (but don't wait until the last minute to book your hotel! December in Sydney is peak season, and while there are many hotels in the area, they tend to get booked quickly as summer nears!)

Update: 127 registered attendees so far!

💡 For students, the yearly IEEE (or ACM) membership costs less than USD 20. And leads to a #FOCS2025 registration fee reduced by USD 80...

An update on registration: as in previous years, the IEEE member reduced fee does also apply to ACM members! We have updated the registration page and process accordingly. focs.computer.org/2025/register/
