 After securing the island , the Allied forces developed Labuan into a significant base . The 24th Brigade left from the island to capture the eastern shore of Brunei Bay in late June , and the island 's airfield was repaired and expanded to host Royal Australian Air Force units . While occupying Labuan , the Allies had to reconstruct the island 's infrastructure and provide assistance to thousands of civilians who had been rendered homeless by the pre @-@ invasion bombardment . Following the war , a major Commonwealth War Graves Commission cemetery was established on Labuan .
