45 mins: Gaitan gets the first try of the second half as Argentina capitalise on a big overlap on the left-hand side. Quesada had a slow start to the night with the boot, but he slots a great effort from the touchline.

Felipe Contepomi comes on for Juan Fernandez Miranda in the centres.
40 mins: With the Gosford crowd still celebrating the score, referee Williams whistles for half-time.

37 mins: Namibia pounce on an Argentine error on halfway and make a rare foray in to the other half with Hakkies Husselman to the fore.

31 mins: The backs are on the scoreboard. Quesada spots a gap, draws the defence and slips the ball to Juan Fernandez Miranda in the tackle for a simple touch down. Quesada adds the two points.
Argentina 20-0 Namibia
27 mins: Quesada, probably frustrated by the profligacy with the ball in hand goes for goal and lands his first kick of the night, a penalty.
Argentina 13-0 Namibia
26 mins: Juan Martin Hernandez slips with a man outside and the Namibian defence stretched. Another chance goes begging.
24 mins: Argentina miss out again when they dawdle in the backs and Namibia's cover defence ushers them in to touch.
21 mins: Argentine ill-discipline is costing them dear near the Namibian line. The African minnows again clear their lines, but like a boomerang, Argentina will be back.
19 mins: Argentina finally get across the line. The forwards drive over from five metres out and number eight Pablo Bouza picks up and touches down. Quesada misses again, hitting the upright.
