GWS have proved last week's Orange Tsunami AFL onslaught was no fluke, kicking 10 goals to three after halftime to overwhelm Melbourne by 49 points.
Following on from their record 14-goal third term against Brisbane, the Giants' efficiency was elite and they beat the Demons 19.5 (119) to 9.16 (70) on Sunday in Alice Springs.
Giants onballer Finn Callaghan had a day out, with a whopping 797m gained, 31 possessions and two goals.
In his first game against his old club Melbourne, Clayton Oliver racked up 28 disposals despite a hard tag from Jack Steele.
GWS have recovered to win two in a row for the first time this season and are 6-6 going into their bye, after losing three of their first four.
