Lonhro was then sent to Melbourne for a rematch with Sunline in the Caulfield Stakes-Gr1 (2,000m). A field of seven lined up, but all race discussions were whether Sunline as a 7yo would return to form and if Lonhro, having his first start beyond 1,600m, would be as effective over 2,000 m. Sunline assumed her usual front running style, and Lonhro stalked for most of the race in about third position. Little changed up to the 800m where Sunline quickened from Ustinov, and Lonhro started the long chase with Distinctly Secret heading the rest. Around the turn, Sunline raced clear of Ustinov with Lonhro steadily making ground but giving the mare a huge head start. By the 300 m, Sunline was over three lengths clear as Lonhro settled into his task. Inside the final 50m, Sunline and Lonhro were level with the mare fighting back strongly, but her younger rival edged in front to win by a half neck in race record time of 2:00:60.
