Dozens of people from the Northern Territory who served in World War I have not been accounted for by historians, new research has found.
Charles Darwin University PhD candidate Norman Cramp says analysis of war records and other research has helped him to uncover the forgotten names of men who were likely from the NT and fought in the conflict.
He believes there could be up to 40 WWI NT soldiers who have not been included in the 360 figure widely accepted by historians.
Mr Cramp, who is also director of the Darwin Military Museum, says that would be significant as the NT's population was just 1500 at the time.
"There is a big piece of the Territory that is missing from our WWI history," he told AAP ahead of Tuesday's Anzac Day commemorations.
In his PhD studies, Mr Cramp is trying to prove how many people from the NT served in the war to establish what impact the conflict had on the frontier territory.
He hoped also to track down exactly when those soldiers left Australia, what they did before they left and where they served.
Anzac Day in Darwin will be marked by the traditional dawn service at the Darwin Cenotaph followed by the march up the Esplanade.
The ceremonies come a little more than a month after Darwin also marked the 75th anniversary of the bombing of the city during World War II.
The attacks by Japanese bombers in 1942, killed more than 200 people, though the exact figure may never be known with some bodies buried in makeshift graves.
The attacks involved 188 aircraft launched from four Japanese aircraft carriers in the Timor Sea, followed by a second wave of 54 bombers supported by more than a dozen ships, destroyers and submarines.
