Ola Kamara scored a hat trick as Norway dealt Bert van Marwijk a rude awakening in his first match as Australia coach with the Socceroos slumping to a dismal 4-1 loss in Oslo on Friday.
The hosts, who sit 20 places below the 37th-ranked Socceroos, dominated from the start and were full value for their win in front of a sparse crowd at a bitterly cold Ullevaal Stadium.
Three goals from the LA Galaxy's Kamara and a header from Tore Reginiussen secured the emphatic victory after Jackson Irvine had given the Socceroos the lead with a 19th-minute header.
