A pause in a Kentucky Derby connection to Australia's stallion rosters

Across a three-year period, Coolmore Australia proudly stood two US Triple Crown winners on its Jerry Plains roster.

In 2019, Justify joined American Pharoah as the highest-profile American shuttlers in a generation. The former stood for five seasons and was crowned champion Australian first-season sire in 2022/23, the first shuttler to do so since More Than Ready in 2004/05.

American Pharoah’s impact was less immediate, but stronger at the top end having sired triple Group 1 winner Riff Rocket and fellow Victoria Derby winner Goldrush Guru.

Whether it was because of the disruption the pandemic caused to the market, or simply Coolmore’s international strategy, American Pharoah last served in 2021 and Justify in 2023.

Since then, there has been no Kentucky Derby winner on an Australian stallion roster, a pattern that held in every year from 1996 until 2021, except 2016.

There have been nine separate Kentucky Derby-winning sires since 1996 and Coolmore Australia has led the line in that regard, shuttling four winners of the ‘Run For The Roses’ since establishing its presence at Jerrys Plains in the Hunter Valley.

Vinery Stud, Arrowfield Stud, Darley and Eliza Park have also chanced their arm with Kentucky Derby winners in Australia in that time, with mixed success.

Coolmore‘s first dalliance with bringing a Kentucky Derby winner to Australia was with 1995 victor Thunder Gulch.

Arriving at Jerrys Plains just a few months after Coolmore had taken over management of the property, Thunder Gulch covered 86 mares in 1996 at a fee of $30,000.

Thunder Gulch’s seven Australia sojourns produced 20 stakes winners and 298 winners overall from 423 runners, among them Group 1 winners Tempest Morn, Shot Of Thunder. And Tully Thunder.

His legacy in Australia was carried on by his daughters, who have produced 18 Australian stakes winners, highlighted by Group 1-winning filly Montoya’s Secret.

Coolmore then doubled down on Kentucky Derby winners when it brought 2000 hero Fusaichi Pegasus to Australia in 2001.

Purchased for a then world record US$70 million (AU$105 million) by Coolmore after his racing career, Fusaichi Pegasus carried a considerable reputation into his stallion career and would stand for $110,000 (inc GST) in his first season in Australia, serving 123 mares.

From that first crop came seven stakes winners, among them black-type winning two-year-olds Dr Green and Flying Pegasus.

By far his best horse bred from his seven seasons shuttling to Australia was the three-time Group 1 winner Haradasun. His time at Jerrys Plains saw him produce 27 stakes winners and 343 winners overall from 503 starters.

In between that Coolmore pair, Vinery Stud shuttled 1998 Kentucky Derby winner Real Quiet (Quiet American) to its newly established operation from 2000 until 2002.

Real Quiet went within inches of winning the Triple Crown, just edged out in the Belmont Stakes and his brief Australian foray yielded three stakes winners and 36 winners overall from 74 runners.

When Darley ramped up its Australian presence with the purchase of Woodlands Stud in 2008, it also looked to use its international strength with a host of new stallions, including the two horses that had quinellaed the 2007 Kentucky Derby, Street Sense and Hard Spun.

Street Sense stood that first season at Kelvinside for $55,000 and was well-supported with a book of 131 mares. His second crop proved fruitful with six stakes winners, among them Group 1 winners Sense Of Occasion and Politeness.

Further Australian-bred Group 1 winners would follow with star three-year-old Hallowed Crown, and the top mare Dixie Blossoms.

His five Australian seasons yielded 170 winners and 12 stakes winners from 249 runners.

Big Brown, the winner of the Kentucky Derby in 2008, arrived at Vinery Stud in 2010, standing at $44,000. He shuttled to Australia for four seasons with 130 winners from 229 runners, with four stakes winners.

Eliza Park secured 2010 Kentucky Derby winner Super Saver for what proved a one-season Australian appearance in 2011. That crop yielded 13 winners.

The 2011 winner, Animal Kingdom was subject to a successful majority ownership play by Arrowfield in late 2012. He rewarded that faith by winning the Dubai World Cup the following March, before heading to the Hunter Valley to begin his breeding career later that year.

At a fee of $38,500 (inc GST), he attracted 94 mares in that first season and from that crop came Oleksandra, who would go on to win the Jaipur Stakes in the United States. Australian Derby winner Angel Of Truth and two other stakes winners came from his second Australian crop. He was eventually sold to Japan with his four Australian crops featuring 132 winners, six at stakes level, from 184 runners.

Coolmore renewed its enthusiasm for Kentucky Derby winners standing in Australia with American Pharoah, who in 2015 became the first horse since Affirmed in 1978 to win the Triple Crown.

He shuttled for five seasons to Australia and from those trips have emerged 204 winners from 298 runners, among them 11 stakes winners.

American Pharoah spent the 2026 Northern Hemisphere breeding season in Japan.

Coolmore’s second Triple Crown winner Justify made a rapid impression, attracting 561 mares across his four seasons in Australia, which were spread across five years.

Commercially, his progeny performed well and from his first crop came star filly Learning To Fly, who won three stakes races as a two-year-old and was narrowly beaten in a Group 1 as a three-year-old.

Another two-year-old star emerged from his second crop in Storm Boy, who was favourite for the Golden Slipper before running third.

Justify, as things stand, has 11 stakes winners conceived in Australia. They came from 195 runners among them 145 winners.

But as the cards have fallen since, there have been no other Kentucky Derby winners headed to Australia.

Sovereignty, the 2025 winner owned by Godolphin, might be a chance once his racing career is completed, but Darley has tended to source horses out of Europe for shuttling purposes in recent years.
