"Weeroona" became part of the United States Army permanent local fleet under the Southwest Pacific Area command's supply organisation, United States Army Services of Supply, Southwest Pacific Area (USASOS SWPA), and was used extensively serving as a quarters ship for American maritime personnel. As part of the Small Ships Section the vessel was given the local fleet number S-195 and perhaps also as CSQ-1. "Weeroona" was used as a quarters ship by Australian personnel under contract to the U.S. Army's Small Ships Section in Sydney and New Guinea. The ship was also used by U.S. Army Signal Corps personnel, some of whom were setting up small ships as communications ships, as barracks and dubbed CSQ for communications ship quarters. "Weeroona" was towed from New Guinea to the Philippines to support Allied forces there at Leyte Gulf and eventually serving as a barracks and convalescent ship in Manila until towed back to Sydney, where she lingered in the harbour until broken up in 1951.
