OTR International Coffee Day Offer – Free Coffee Upgrades

OTR is celebrating International Coffee Day with a complimentary upgrade on all C Coffee purchases. The promotion runs for one day only on Wednesday, 1 October 2025, and is available at participating OTR locations across Australia.

Customers who order any size coffee will automatically receive a free upgrade to the next size up, meaning a small coffee can be bumped to a medium, or a medium to a large, at no additional cost.

How It Works

The upgrade applies to all hot and iced coffee varieties within the C Coffee range, including espresso, lattes, cappuccinos, and iced coffees. Customers simply need to order in-store on the day to receive the complimentary size increase.

The promotion is not tied to app orders, vouchers, or coupons — the upgrade is automatically applied at the counter as part of the International Coffee Day celebration.

Conditions and Limitations

The offer is valid for one day only and limited to in-store purchases. It does not apply to extras or add-ons such as syrups, alternative milks, or specialty customisations, which remain charged as normal.

While stocks last, the promotion is available at all participating OTR stores serving C Coffee. Customers are encouraged to check local store participation to ensure availability.
