In a first half played at blistering pace, Australia went ahead after German keeper Max Weinhold failed to control a shot from Glenn Turner and Kieran Govers fired the volley rebound through his legs.
Germany levelled minutes later with a low penalty corner flick by Moritz Fuerste and the 1-1 scoreline at halftime was a fair reflection of the action.
Germany looked more dangerous at the start of the second half but it was Australias Turner who put his team back in the lead, sneaking the ball over Weinhold who had gone to ground to save two previous attempts.
Germany had a goal disallowed 12 minutes into the second half when Oliver Deecke volleyed an aerial pass over the Australian keeper, the umpire deciding after a video referral that Deecke had raised his stick above shoulder height.
