 Blucher Point was reached on 28 December, where the 2/13th Infantry Battalion regained contact with the retreating Japanese and fought a sharp contact.Elsewhere, on 26 December US and Australian forces landed on Long Island, while US forces landed further west at Saidor on 28 December.This sealed the Japanese decision to quit the Sio area, and over the course of two weeks the Australians advanced swiftly up the coast, overcoming only "sporadic opposition" as the Japanese continued to withdraw to the west towards Madang, seeking to avoid being cut off by the forces at Saidor.
