Cummings’ reputation grew with each spring. In 1967, Galilee became the first and only horse to win the Caulfield Cup, Melbourne Cup and Sydney Cup in the same season. By the mid-1970s, Cummings had built a stable that dominated the Melbourne spring, winning Cup quinellas five times and collecting major trophies with horses such as Think Big, Gold and Black, Hyperno and Kingston Rule. His wins were not limited to stayers. He trained sprinters, milers and two-year-olds with equal authority, winning four Golden Slippers, five Cox Plates, seven Caulfield Cups and thirteen Australian Cups.
His stables at Randwick and later Flemington were known for their calm atmosphere, consistent routines and steady progression of horses from one level to the next.
Cummings had an instinctive sense of timing and placement, and his horses were rarely rushed.
Many improved out of sight under his care – not only champions, but also good, honest gallopers that he could keep sound, fit and happy for long campaigns.
