DUNDEEL SEX BIAS - is it FACT or FICTION?
FROM BIAS TO BALANCE - SMART MONEY FOLLOWS THE DATA
DUNDEEL FILLIES FLIP FACTS AS DATA SAYS BUY THE FILLIES
Dundeel Filly IDLE FLYER became the
tenth Gr1 winner for her sire, who is rightly regarded as an outstanding sire in his own right, with
500 Winners, 40 Stakes Winners and 33 Stakes Placegetters.
However, from his early crops his record with fillies was not as strong as that of his colts.
Today that has turned around and is looking far more balanced and now in alignment with industry norms.
His
fillies strike rate has certainly improved as time has gone bye, and he now has
two female Gr1 winners as
Idle Flyer joins last year’s SA Derby winning filly
Femminile.
For the record let’s take a look at the
stats for Dundeel in terms of
colts-vs-fillies as sourced from Arion as at 12/04/2026.
A study by
Breednet.com published today has taken a look at the
sale ring data for
Dundeel since 2017 when his first crop of yearlings entered the sale ring.
Breednet.com put together a
table of yearling sale prices from the
four major sales: Inglis Easter, Magic Millions Book 1, Inglis Premier and
Inglis Classic, being the top end of the commercial market in Australia.
2022 was a pivotal sales year for Dundeel as that crop was his
first conceived off his raised service fee which jumped from
$27,500 to $66,000 in
2019 and that was followed with an increase in
2023 to
$82,500 which is the fee his
current crop yearlings were conceived and that increased again in
2024 to
$88,000.
His
yearling averages for his colts since that year has remained
relatively consistent, while the fillies average fluctuated wildly due to several reasons including, a lack of fillies being sold at the sales, the conformation and pedigree of those fillies, and a widespread misunderstanding held by yearling buyers (and obviously auction houses) that fillies may not have been as successful.
However,
racetrack statistics prove his fillies have evened-up the data differential compared with the colts and
market awareness among the professional buyers has translated to the sale ring where
this year he achieved his best fillies average since 2022.
Still his fillies in 2026 remain tremendous value compared to the colts, especially when
analysing cost-verse-return, and that is before considering the
additional return achieved for the
residual value of his well-bred fillies heading off to the breeding barn upon racetrack retirement.

Analysing data is imperative in successful thoroughbred trading where opportunities can be found to deliver excellent financial opportunity, in addition to the enjoyment of racing for our sport’s own rewards.
The publishing of this data by
Breednet.com reinforces what we had identified this year, that
well-related fillies bred on a proven cross would offer excellent opportunity to a rewarding outcome for our Dynamic Owners.
That’s why we purchased a DUNDEEL (NZ) ex FAIROUZ (USA) (by DUBAWI (IRE)) filly from the Inglis Classic.
The fact she was
LOT 1 in the catalogue is a terrific opportunity for buyers as the market hasn’t had time to establish itself with average and median.
Often the early lots in a sale can offer incredible value.
As it proved to be for
Dynamic Syndications / Dean Watt Bloodstock when we
purchased our
Dundeel filly for just $80,000 + GST from Arrowfield Stud.

Dundeel
* When a stallion sires Group One winners he earns respect.
* When he sires sons who sire Group One winners he earns influence.
* When those sons command valuations north of fifty million dollars he earns permanence.
That is where Dundeel now sits.
Arrowfield’s own assessment adds further weight.
They have stated that Dundeel has left more two year old Group One winners than I Am Invincible and more Group One performers from his Australian crops than Zoustar.
Those are two of the most commercially dominant stallions of the modern era.
To compare Dundeel in that space signals a genuine shift in perception.
He is no longer simply the Classic staying influence. He is a complete stallion building a dynasty.
That broader context is precisely why we were so determined to secure our Lot 1 filly from the Inglis Classic.

Our Filly - Lot 1 by DUNDEEL x FAIROUZ (USA) (by Dubawi)
On pedigree alone she stood out.
By Dundeel and out of a Dubawi mare, she represents a fusion of Australian Classic stamina and elite international blood.
The Dundeel over Dubawi cross has already produced exceptional results, with the three prior runners all winners and two at Group One level.
That is not theoretical potential. That is proven performance.

Our analysis ranked her pedigree as the highest rated genetic page in the Inglis Classic catalogue.

Lot 1 after we purchased her
We saw scope, balance and athleticism physically.
We saw Classic distance potential on paper, ideally suited to the mile to 2400 metres range where prestige and residual value are built.

We saw a filly with the profile to develop into a three year old and four year old of significance, and beyond that, a broodmare with genuine commercial appeal in a market that is increasingly rewarding daughters of stallions who are building sire lines.
The timing could not be more compelling.
Arrowfield has publicly stated that their current crop of Dundeel yearlings is the best group they have ever offered, conceived off an eighty two thousand five hundred dollar service fee and out of elite mares including daughters of Snitzel and families tracing back to champions such as Winx and Beholder.
In other words, the best bred progeny of Dundeel are only now reaching the racetrack and the salering.
The first wave of sons is already succeeding.
The second wave is even better credentialled.
That matters to owners.

Our Filly at Booleroo Spelling Farm (Shane Rose) on 20/2/26
When you secure a filly like our Lot 1 purchase, you are not simply buying into today’s form.
You are positioning yourself within a rising sire line at the point where momentum is accelerating.
Coolmore’s acquisition of Super Seth (by Dundeel) is not an isolated headline.
It is confirmation that the Dundeel branch of the High Chaparral legacy is strengthening its grip on the Australian breeding landscape.
For Dynamic Syndications, that is exactly the type of opportunity we seek.
We analyse deeply. We look beyond the immediate sale ring theatre.
We assess where the market is heading, not just where it has been.
In this case, the indicators aligned.
A filly by a stallion ascending into elite company as a sire of sires.
Out of a Dubawi mare adding international class.
Bred on the exact cross of Champion 3yo MILITARIZE
From Arrowfield, one of the most respected nurseries in the country.
Offered as the very first lot of a major sale, and secured at a price we believe represents outstanding value relative to her upside.
This is how dynasties are joined.
This is how strategic buying creates opportunity.
Dundeel anchored High Chaparral’s legacy in Australia.
Through sons like Super Seth and Castelvecchio he is extending it.
Through daughters like our Lot 1 filly, that influence will flow into the next generation.
We believe she represents more than a well bought yearling.
She represents alignment with a stallion whose trajectory is still climbing, whose commercial relevance is strengthening and whose best bred progeny are only now emerging.
That is why we targeted her.
That is why we secured her.
And that is why we are excited about what the future holds.
STOP PRESS: Announcement 13 April 2026
The unraced 2yo Half Brother to our filly named THE AUTUMN CHOICE (The Autumn Sun / Fairouz (USA)) barrier trialed at Gosford on 13-4-26 in a 2yo trial winning his trial convincingly in quick time for trainer Geoff Allendorf and jockey Jon Griesdale.
