Park visitors must not consume any alcohol in any such alcohol-free zone, except with the written permission of the Trust. Park visitors must place all empty bottles in the appropriate bins provided in the Parklands or take them out of the Parklands with them.

In 2026, the rules for drinking alcohol in Centennial Park depend heavily on which specific "Centennial Park" you are visiting, as several major locations share the name. At Centennial Parklands in Sydney, Australia, the consumption of alcohol is generally permitted for personal use, provided guests behave in a responsible manner and do not cause a nuisance. However, for organized events or large groups, you may need written permission from the Trust. Conversely, at Centennial Center Park in Centennial, Colorado, alcoholic beverages are strictly prohibited unless you have obtained a specific Alcohol Permit Application from the City, which typically involves a fee (around $25) and is tied to a facility reservation. Similarly, at Centennial Beach in Naperville, alcohol and glass containers are entirely banned to ensure the safety of swimmers. Before heading out, it is essential to check the local municipal or parkland website for the specific 2026 ordinances of your location, as "dry zones" can be implemented seasonally or for specific community events to maintain public order and safety.
