Long Tan Day is observed every August 18 to honor the bravery and sacrifice of Australian and New Zealand soldiers who fought in the Battle of Long Tan during the Vietnam War. This solemn day commemorates the pivotal engagement where D Company of the 6th Battalion, Royal Australian Regiment, faced overwhelming odds. Typical customs include attending local memorial services, observing a minute of silence at 12:40 PM AEST, and reflecting on the courage of those who served. Organizations such as Legacy Australia and the Returned and Services League of Australia (RSL) often coordinate fundraising drives and public appeals to support veterans and their families. Many local businesses, particularly those owned by veterans, may offer special services or discounts as gestures of gratitude. The day encourages individuals to contribute to veteran support services and participate in memorial events.
