The iconic Sydney circuit prepares for a massive Doncaster Mile Day card on Saturday, headlined by four Group 1 features, including the $2 million classic for the three-year-olds (2400m).
A high-quality field of 13 young stayers has been assembled, and bookmakers are finding it nearly impossible to split the leading contenders.
Currently clinging to the top of the Australian Derby odds at Ladbrokes is the Bjorn Baker-trained Green Spaces ($3.20).
The Street Boss colt has seen support following a favourable draw in barrier six.
While he hasn’t tasted victory since his dominant three-length display in the Group 3 Spring Stakes last November, his preparation has been timed to perfection.
His latest effort was a flashing light performance, storming home for third at big odds in the Rosehill Guineas (2000m)—historically the premier form reference for this race.
Rachel King stays aboard the colt, who looks desperate for his first crack at the mile-and-a-half trip.
Nipping at his heels is the Ciaron Maher-trained Observer ($3.30), who faces a slightly tougher task from barrier 12.
The son of Ghaiyyath is one of the few runners with proven staying credentials, having claimed the Group 1 VRC Derby (2500m) in the spring.
His autumn campaign has been equally impressive, securing the Autumn Stakes and Australian Guineas double before a solid third in his Sydney debut in the Rosehill Guineas.
With that right-handed run now under his belt, he is expected to relish the rise in distance as he chases a third elite-level trophy.
In a major boost, record-breaking jockey James McDonald takes the mount for the first time.
Australian Derby betting favourites saluted six times from 2006 – 2025 most recently with Criterion (2014), Hitotsu ($3.30 in 2022), Riff Rocket ($2.20 in 2024), and the filly Aeliana ($2.25 in 2025).
The only other runner under double figures is the Ben, Will & JD Hayes-trained Storm Leopard ($4).
The chestnut enters the deep end for his Group 1 debut on a seven-day backup following a brilliant 1.8-length win in the Group 2 Tulloch Stakes.
Tommy Berry sticks with the up-and-comer from barrier five as he looks to become the first since Quick Thinker (2020) to complete the Tulloch/Derby double.
For those hunting value, the Team Hawkes-trained Federalist ($11)—fifth in the Rosehill Guineas—and the Kiwi raider Road To Paris ($12) represent the pick of the outsiders.
Road To Paris is attempting to join Mongolian Khan (2015) as a winner of the prestigious NZ Derby / Australian Derby double.
The 2026 Australian Derby is scheduled as Randwick Race 9 at 5:15pm (AEDT) as the penultimate event on Saturday’s race card at Randwick.
