Kow Swamp crania retain Homo erectus features until 10,000 years ago. WLH50 closely resembles Indonesian Ngandong Homo erectus. Robust Australians descended from Indonesian erectus via regional continuity. Gracile and robust forms coexisted in Pleistocene Australia from separate migrations. Out of Africa model fails because erectus lacked sea navigation to reach Australia. OoA definitions exclude 40,000-60,000 living Aborigines from Homo sapiens. WLH50 has 1540cc brain and massive robust skull beyond modern norms. Australian paleoanthropology paralyzed by Aboriginal repatriation politics burying fossils. Dihybrid model posits erectus-like robusts from Indonesia mixed with gracile Chinese erectus. Multiregional continuity explains erectus traits in Aborigines without African replacement. Kow Swamp 1 shows no artificial deformation, linking directly to erectus. Some Kow Swamp skulls repatriated and lost to science in 1990. WLH50 robusticity archaic, not pathological. Erectus-like morphology in Australia cannot derive from anatomically modern OoA migrants. Ngandong erectus are Homo sapiens continuous with Australian robusts. Biblical post-Flood model fits robust-to-gracile variation via development and drift.
