Prior to European contact, a Melanesian settlement named Numbay was at this location near the mouth of the Numbay River that empties into Humboldt Bay. On September 28, 1909 a Dutch navy vessel commanded by Captain F. J. P. Sachse landed at Humboldt Bay near the mouth of the Numbay River and established a camp named Kloofkamp at this location. On March 7, 1910 the Dutch established a settlement at this location that they named Hollandia and from this location administered Dutch New Guinea.

Wartime History
During April 1942 occupied by the Japanese Army. The Hollandia area was developed into a base area with three airfields: Hollandia Airfield, Sentani Airfield and Cyclops Airfield with Tami Airfield further to the east. During April 1943 until April 1944, targeted by Allied aircraft, the airfields were neutralized by the middle of April 1944.

By early 1944, the Japanese garrison at Hollandia consisted of the remnants of the Japanese Army 41st, 20th and 51st Divisions with many support and air personnel.

During March 1944, a reconnaissances party was landed by submarine USS Dace SS-247. Two groups were landed which included US Army CIC, Australian, Indonesian and four New Guinea natives: Mariba, Yali, McNicol and Buka.  Only 7 of the 12 landed were recovered, but revealed a weak Japanese presence in the area.

General MacArthur planned a daring leapfrog operation to bypass stronger Japanese garrisons along the north coast of New Guinea for a landing further to the west at Hollandia which was weakly defended in an operation aimed at capturing the airfields in the area and development of Hollandia into a base for future operations including the liberation of the Philippines.

Battle of Hollandia
On April 22, 1944 an American amphibious task force code named "Operation Reckless" landed U.S. Army troops at Humboldt Bay and Tanahmerah Bay near Hollandia. Meanwhile, "Operation Persecution" the amphibious task landing at Aitape is undertaken protect the eastern flank. The landing is primarily by troops from the U.S. Army 41st Infantry Division. They are supported by M4 Shermans from the United States Marine Corps (USMC) 1st Marine Division, 1st Tank Battalion, Company A but a swampy area beyond the beachhead limits their effectiveness.

Japanese were caught by surprise and weakened by aerial attacks and bombardment and offered little resistance. In the landing area, many Japanese who were starving or rear echelon troops were willing to surrender unlike in earlier landings and battles. The remaining Japanese retreated inland and attempted to escape westward. Advancing, the Americans encountered faced muddy conditions, swamp and jungle that made the drive inland difficult.

After the battle the Hollandia area was immediately repaired and developed into a major U.S. Army base and staging area for future operations including the landings at Biak, Leyte and Luzon. Hollandia was designated "Base G" by U.S. Army letter base designation. Hollandia remained an important American base until the end of the Pacific War. During late April 1944 until the end of the Pacific War, designated U.S. Army as Army Post Office 565 (APO 565).
