Coolmore predicting big future for Home Affairs following dream Golden Slipper result
In 2022, in an article by this correspondent crystal balling the next big thing in Australian stallions, all roads led to one new sire who was entering stud just after his fourth birthday.
Coolmore Stud were convinced they were onto a winner, almost a no-brainer, based on the template set by their most successful Australian stallion of all time.
“Fastnet Rock’s sireline, race record and pedigree gave us great confidence,” said the stud’s nominations and sales manager Colm Santry at the time, “and it’s the same with Home Affairs (I Am Invincible).
“These champion three-year-old colts in this country tend to make sires, and it was Home Affairs and Anamoe who were the cream of their crop.”
That enthusiasm was backed by a range of respected voices looking for key markers in a potential stallion.
“In terms of racing ability, Home Affairs was dominant,” said major buyer James Harron, citing the colt’s “almighty” three-length victory in Flemington’s Coolmore Stud Stakes (Gr 1, 1200m) against the best of his age, and his “tremendous” WFA win over Nature Strip (Nicconi) in the Lightning Stakes (Gr 1, 1000m) at the same course at his next start.
“And physically, he’s an imposing, masculine horse, with great presence and strength – very much in the Australian speed mould which everyone is always looking to replicate.
“He’s by one of the dominant stallions of recent years in I Am Invincible, and from an outstanding female line. His dam is a half-sister to the very promising stallion Russian Revolution, and hails from the hallowed Fanfreluche family.
“He’s an outstanding prospect for Australian breeding.”
Fast forward almost four years, and rarely can the hopes, dreams, calculations and expectations surrounding a stallion have been fulfilled more thoroughly at such an early stage. Australasian breeding, clamouring for a new dominant sire as the sun sets on a generation of greats, may have a very special one in its midst.
First, Home Affairs was feverishly popular. Though standing initially at a relatively hefty first season fee of $110,000, he covered 203 mares in 2022. He served 189 at $99,000 in year two, before 227 and 205 in the past two seasons, at $82,500.
Next, without a runner on the ground, Home Affairs’ stock was of such quality that he produced the sale toppers at the two most important yearling auctions in the southern hemisphere in 2025.
At Magic Millions Gold Coast, Japanese trainer Mitsu Nakauchida paid $3.2 million for a filly out of outstanding mare Sunlight (Zoustar). At Inglis Easter, Gai Waterhouse and Adrian Bott went to $3 million to secure a colt out of their former topline mare Shout The Bar (Not A Single Doubt), in league with Kestrel Thoroughbreds.
Now, at his first attempt, Home Affairs has sired the winner of Australian breeding’s most important event, the Golden Slipper (Gr 1, 1200m), after Guest House’s barnstorming victory in the world’s richest two-year-old race at Rosehill on Saturday.
The hulking Mick Price and Michael Kent Jnr-trained colt – setting up his own stud future – became Home Affairs’ third stakes winners from just 27 runners, at 11.11 per cent. He has seven stakes horses, at 25.93 per cent. He tops the first season sires’ tables on both sides of the Tasman, with one of his stakes winners having come in New Zealand.
And on Saturday afternoon, he seized the front-running on Australia’s two-year-old sires’ list.
After the Slipper triumph Coolmore – hit by the untimely deaths of Wootton Bassett (Iffraaj) and So You Think (High Chaparral) last spring – will with good reason be feeling mightily pleased with the ballistic start the seven-year-old Home Affairs has made.
It’s also come at a time when Australia has been almost desperately searching for its next hot stallion to step up in the wake of the dominant 20-somethings of the modern era such as Snitzel (Redoute’s Choice), I Am Invincible (Invincible Spirit), Written Tycoon (Iglesia), and of course Fastnet Rock (Danehill).
“The stars have aligned for us, thankfully,” Santry told ANZ News on Sunday.
“The country’s been crying out for a new leading sire, and hopefully Home Affairs is the one.”
The experienced Santry went further, buoyed by the knowledge Home Affairs had emulated two of the greats – Danehill (Danzig) and Extreme Choice (Not A Single Doubt) in leaving a Slipper victor in his first crop, those winners being Danzero in 1994 and Stay Inside in 2021, who both – like Guest House no doubt will – became sires.
“Home Affairs is well on the way to being an elite stallion already,” Santry said. “I believe he’ll be the best sire from that whole sireline in this part of the world.”
That’s a sizeable call, given that Invincible Spirit sireline includes I Am Invincible himself, the three-time champion stallion.
But Coolmore are supremely confident – not only due to Home Affairs’ sales and early racetrack results but the strong support he’s had from breeders. This list is headed by Coolmore itself, who sent most of their best mares to him last spring after losing Wootton Bassett and So You Think.
“For us, I don’t say something will be a low risk stallion to be successful, because you never know, and the proof will be in the pudding,” Santry said.
“But Coolmore supported the horse heavily last season. We had so much confidence in the horse being successful that we bred all our best mares to him last year, before he had a runner.
“His numbers are tracking the right way. We were of course hoping that would be the case, and it looks like that success is going to happen.”
Saturday’s Slipper was a triumph for connections, with Price celebrating his first win in one of Australia’s “Big Four” races after buying Guest House from Newgate’s draft at the Magic Millions Gold Coast Yearling Sale for $270,000, in conjunction with Tim Rogers Bloodstock and the Roll The Dice Racing group whose familiar colours he bears.
But it was also, Santry said, a vehemently encouraging win for the breeding scene as a whole, since Home Affairs has been so strongly supported.
“Yes, it was a very important day for Coolmore, but it’s like everybody has a piece of Home Affairs. He’s been a wicked popular stallion,” said Santry. “It was fantastic to see what he did yesterday, winning a Slipper from his first crop.
“I spoke to one breeder this morning who was over the moon. He’s got 11 Home Affairs foals on the ground.
“The industry has backed him to the hilt. They’ve believed in him, like we did, and now hopefully we’ll all be rewarded.
“A lot of the commercial breeders in this country have exposure to this horse, and I’m delighted for all of them. It’s very important for Coolmore that the clientele get rewarded.”
Given his trajectory so far, no crystal ball is needed to predict a hefty service fee hike for Home Affairs in 2026 – possibly almost double his current mark of $82,500 (inc GST).
The stallion batted at 82.9 per cent fertility in 2024, the latest season for which data is available. “He’s very fertile. He only has to serve a mare once,” said Santry.
Santry noted Home Affairs also fitted the mould of Fastnet Rock and other leading sires in Australia, in terms of success in the 1000 to 1200 metres range.
“Fastnet Rock won one Group 1 in the Lightning Stakes at Flemington, over 1000 metres, and his other one in the Oakleigh Plate over 1100 metres,” he said. “He was the fastest son of a champion sire, in Danehill, to stand at stud.
“And now we have the fastest son of a champion sire in I Am Invincible at stud.
“Those five and six furlong speed horses make champion sires in Australia. That sort of speed is so important in this country. The horses that can sire 1000-metre and 1200-metre horses can eat into a lot of race programming here – the Coolmore Stud Stakes, the Slipper, the Everest, the Lightning, the Newmarket, and so on.
“They’re the horses the market really wants in this country. So It’s very important that Coolmore have the best one, and we might just have the best sire in the country going forward into the future.”
That said, and while Home Affairs didn’t race beyond 1200 metres in his ten starts, the sizeable Guest House looks likely to succeed at distances greater than he traversed on Saturday, and in his meritorious third in the Blue Diamond Stakes (Gr 1, 1200m).
“With the turn of foot he showed in the Slipper, you’d think he’ll get 1400 or 1600 pretty easily. He’s a beautiful big horse,” Santry said. “So I wouldn’t be surprised to see him in a Guineas later on.”
At the same time, it could be argued Guest House – bred by Love Racing PL, Henderson Racing and Breeding, and G1g Racing and Breeding – was made for Saturday’s win.
Among the 15 stallions in the first four generations of his pedigree, four are Slipper winners, all of them damsires. They are his own damsire Stratum (Redoute’s Choice); Home Affairs’ damsire Flying Spur (Danehill); I Am Invincible’s damsire Canny Lad (Bletchingly); and Guest House’s third damsire, Vain (Wilkes).
Meanwhile, as for Home Affairs’ two sale toppers, both are awaiting their first starts. The daughter of Sunlight is in Japan and named Lia La La, while the son of Shout The Bar now carries the name of The Railway, a fitting pub-related moniker for a syndicate headed by John Singleton.
