He's not quite Sunline yet, but he's got all the hallmarks of a champion." Sunline, a champion New Zealand mare, had won the Cox Plate for two years running, and the spring clash with Northerly was now widely anticipated. Five-year-old season: 2001–2002 Northerly was spelled for the winter, and started his campaign in Perth, where he won first-up and was defeated second-up with 62 kilograms. He then travelled to Melbourne, where he met Sunline for the first time in the John F Feehan Stakes in mid-September. This time, Damien Oliver took the ride, as Greg Childs was committed to Sunline. The great mare raced clear approaching the home turn, but Northerly rallied in the straight for the narrow, fighting victory that would become his trademark. Greg Childs said "Sunline was at peak fitness. We took off early and he looked a beaten horse. But he nailed us on the line. It was his determination. Often he looked to be struggling but he kept coming". Not meeting again before the Cox Plate, Northerly added Group One wins in the Underwood and Caulfield Stakes, while Sunline edged to favouritism for the Cox Plate with her victory in the Turnbull Stakes. The stage was now set for the 2001 Cox Plate. In typical style, Sunline led the field to the home turn, but – unlike the previous two years, when she raced clear in the straight – the Sydney three-year-old Viscount refused to give in, while Northerly loomed wider on the track. Nearing the line, the three horses buffeted one another on several occasions, and, while Northerly narrowly edged past Sunline and Viscount, the roughhouse conclusion to the race sparked three separate protests – second (Sunline) against first (Northerly) and third (Viscount) against first and second. After lengthy deliberations, stewards dismissed all three protests, and Northerly controversially retained the race. Nonetheless, Northerly had had an outstanding campaign, and the Cox Plate was his fourth win in-a-row. Northerly returned to Perth, and his trainer Fred Kersley chose to run him in the Railway Stakes, which had been moved forward on the calendar. Unfortunately for the "home" crowd, the Cox Plate winner wilted badly in the home straight under 61.5 kilograms, and he finished an uncharacteristic 11th of 16 behind the Lindsey Smith trained Old Comrade, who again defeated Northerly in the Australian Cup in March. Northerly had shown strong lead-up form to the Australian
