Lindsay Park Racing’s Long Leaf (Fastnet Rock) will make his three-year-old debut in Saturday's Gr.3 Vain Stakes (1100m) at Caulfield.
Long Leaf hasn't raced since finishing ninth in the Gr.1 Champagne Stakes (1600m) at Randwick in April.
Co-trainer Ben Hayes said Long Leaf's early spring form would determine whether the colt extends out in trip or is kept for shorter races.
"We'll either go towards the Caulfield Guineas or keep him fresh for the Coolmore Stud Stakes," Hayes said.
"He hasn't put a foot wrong and has grown and strengthened a bit and we were particularly happy with his trial down the straight.
"He was in the same trial as Oohood and they looked to be pretty even on the line.
"He's drawn an awkward barrier so I'm not sure what we'll do but it's a competitive race and we're expecting him to run well."
Long Leaf is a graduate of the 2017 New Zealand Bloodstock Premier Yearling Sale, with the son of Fastnet Rock sold from Gordon Cunningham’s Curraghmore for $750,00 to Adrian Nicol of BBA Ireland.
