Connections of three-year-old Microphone have opted to have to colt bypass the Listed Kensington Stakes and instead head to the Group Two Australia Stakes.
Group One-winning colt Microphone and Silver Slipper winner Time To Reign figure among eight nominations for the Listed Kensington Stakes at Flemington.
Deference has added his name to Godolphin's long list of spring hopefuls from its three-year-old ranks after winning for the first time in four starts.
Golden Slipper winner Kiamichi and runner-up Microphone are among the James Cummings-trained juveniles in line to run in the Sires' Produce Stakes at Randwick.
Microphone and Catch Me have been installed early favourites for the respective Blue Diamond Previews, with both two-year-olds drawing wide in the 1000m races.
