After a six-week break, Colette won at Kembla Grange Racecourse and two weeks later she contested her first stakes race, the Group 3, Adrian Knox Stakes at Randwick Racecourse. Starting as a 2/1 favourite, Colette settled midfield before weaving her way through runners in the first half of the home straight.

Seven days later, Colette contested the Australian Oaks at the same course. This was her first attempt in a Group 1 race. Starting favourite at the odds of 2/1 and with Glen Boss in the saddle, Colette took the lead at the 300-metre mark over the 2,400m distance and won by 2-1/2 lengths.

Racing on the pace throughout, Colette faded late to finish 10th beaten just over two lengths. Jockey Josh Parr was full of praise after the race stating, “Really good.
