HCKSYD 2026

// Taking the system offline for maintenance. We'll be back.

Due to unforeseen circumstances outside of our control, HCKSYD 2026 has been cancelled.

After running HCKSYD every year since 2021, it is also time for our core organising team to take a well-earned break, recharge, and come back stronger.

All ticket holders will be automatically refunded. No action is required. Refunds will be processed back to the original payment method over the coming days.

This is not the end of HCKSYD. We fully intend to return in the future, refreshed and ready to bring the community together again.
