Proxima Dea has maintained her unbeaten record with victory in the Group 1 Crown Oaks (2500m) at Flemington on Thursday, giving the three-year-old filly her sixth win from six starts and a second Group 1 success in less than two weeks.
Trained by David Payne and ridden by Zac Lloyd, the daughter of Tarzino defeated Shameful Impulse by 1.75 lengths, with De Armas finishing third.
The result followed her victory against male opposition in the Group 1 Spring Champion Stakes (2000m) at Randwick on 24 October, completing a spring campaign that has established her as one of Australia’s leading staying fillies.
For breeders and bloodstock participants, the result carries particular significance. Proxima Dea is a full sister to Group 1 Queensland Oaks winner Gypsy Goddess, giving their dam Invisible Coin two daughters successful at the highest level.
Proxima Dea Completes an Unbeaten Spring Campaign
Progressing from a 1400-metre juvenile victory at Randwick in July to Group 1 company within four months, Proxima Dea entered the $1 million Crown Oaks having won all five of her previous starts.
Her preparation included wins over 1600m and 1800m before she captured the Group 3 Gloaming Stakes (1800m) and Group 1 Spring Champion Stakes (2000m).
The Crown Oaks presented another test, with the distance increasing to 2500m and Proxima Dea starting from barrier 19.
Despite covering additional ground during the race, she sustained her effort in the straight to defeat the Rob Blacker-trained Shameful Impulse. Chris Waller’s De Armas finished third.
The Victoria Racing Club confirmed that Proxima Dea completed the Spring Champion Stakes and Crown Oaks double, with Payne indicating the filly would now have a spell following her first racing preparation.
Her progression from 1400m to 2500m has also provided further evidence of the stamina associated with her sire.
Tarzino Adds Another Group 1 Oaks Winner to His Record
Proxima Dea is by Tarzino, the New Zealand-based son of Tavistock who won the Group 1 Victoria Derby (2500m) in 2015.
Now standing at Westbury Stud, Tarzino has developed a record through progeny successful in major staying races.
His notable performers include:
- Gypsy Goddess, winner of the Group 1 Queensland Oaks.
- Jungle Magnate, winner of the Group 1 South Australian Derby.
- Willydoit, winner of the Group 1 New Zealand Derby.
- Proxima Dea, winner of the 2026 Group 1 Spring Champion Stakes and Crown Oaks.
The latest Oaks result is especially relevant because Tarzino has now sired two Group 1-winning daughters from the same mare.
It also adds another major Australian classic to the stallion’s record, 11 years after his own Victoria Derby victory at Flemington.
For breeders assessing stallions with proven staying credentials, these results provide direct racing evidence of Tarzino’s ability to sire horses competitive over middle and extended distances.
Individual performances, however, remain dependent on the dam, physical characteristics, development and training of each horse.
Invisible Coin Produces Two Group 1 Oaks Winners
The female family is central to Proxima Dea’s breeding story.
Her dam, Invisible Coin, is a daughter of champion Australian sire Redoute’s Choice and the mare Christchurch.
Invisible Coin is also a sister to Cheeky Choice, winner of the Group 1 Flight Stakes.
Her mating with Tarzino has produced both Gypsy Goddess and Proxima Dea.
Gypsy Goddess won the Group 1 Queensland Oaks over 2200m in 2022 and finished runner-up in the Group 1 Australian Oaks over 2400m.
Four years later, Proxima Dea has added the Crown Oaks over 2500m to the family’s record, having already won the Spring Champion Stakes.
Proxima Dea Pedigree
| Pedigree position | Horse | Breeding significance |
| Sire | Tarzino | Group 1 Victoria Derby winner and sire of classic winners |
| Paternal grandsire | Tavistock | Established source of middle-distance and staying performers |
| Dam | Invisible Coin | Dam of Group 1 winners Gypsy Goddess and Proxima Dea |
| Maternal grandsire | Redoute’s Choice | Champion Australian sire with an extensive influence on Australian pedigrees |
| Full sister | Gypsy Goddess | 2022 Group 1 Queensland Oaks winner |
The repeated success of this mating is commercially relevant to breeders examining proven crosses and the records of producing mares.
Two full sisters winning Group 1 Oaks races is substantial evidence of the combination’s success in this particular family.
It does not establish that every subsequent foal from the same cross will possess comparable racing ability, but it gives breeders and bloodstock buyers a documented record to assess.
The Yearling Sale That Did Not Produce a Change of Ownership
Proxima Dea’s history also illustrates how a horse’s commercial journey can develop differently from the original sale plan.
Bred by Transtasman Breeders Pty Ltd, she was offered by North Bloodstock at the 2025 Inglis Australian Easter Yearling Sale.
The sale record lists Ciaron Maher Bloodstock as the buyer at $300,000.
However, reporting published by Thoroughbred Daily News Australia and New Zealand on 27 October 2026 establishes that the proposed transaction subsequently fell through after sufficient ownership shares could not be placed.
The filly consequently remained with her breeders.
Her ownership group includes Andy Giles, Caroline Vincent and Hugh Docherty, with David Payne entrusted with her racing career.
What initially appeared to be a completed yearling sale ultimately resulted in the original connections retaining a filly who has now won two Group 1 races.
The sequence is significant for vendors and buyers because it illustrates the distinction between a recorded auction transaction and the eventual ownership outcome.
It also demonstrates why sale price alone cannot provide a complete assessment of a thoroughbred’s subsequent racing prospects.
What the Crown Oaks Result Means for Breeders and Bloodstock Buyers
Proxima Dea’s Crown Oaks victory provides several points of interest for the bloodstock market.
For Tarzino, the result strengthens an established record of producing successful staying horses, particularly at classic distances.
Invisible Coin, another Group 1-winning daughter adds considerably to an already distinguished produce record.
For buyers, the case demonstrates the importance of considering both sides of a pedigree, including the performances of full siblings and the production record of the dam.
The outcome also highlights the limitations of evaluating young horses solely through yearling sale transactions.
Proxima Dea’s development after her 2025 auction appearance has produced a racing record that could not have been established from her pedigree and physical assessment alone.
Any future implications for the value of Invisible Coin’s progeny or Tarzino’s commercial demand will depend on subsequent market activity. The Crown Oaks result provides a significant new reference point, although it does not establish a specific increase in sale values.
A Current Tarzino Ownership Opportunity on Thoroughbred Sales
For prospective owners interested in the sire’s progeny, Thoroughbred Sales currently advertises a Tarzino x Marsh Harbour colt in Victoria.
The colt is listed with Henry Dwyer Racing and is out of the stakes-placed mare Marsh Harbour. His advertised pedigree and profile are separate from the family of Proxima Dea.
Buyers can review the individual listing, assess the available information and enquire directly about the horse’s preparation, ownership terms and current availability.
Thoroughbred Sales also provides a wider selection of unraced thoroughbreds for buyers examining emerging horses by sire, dam, trainer and ownership arrangement.
Proxima Dea’s Spring Carnival campaign is a timely example of the value of following breeding records beyond the sales ring.
With two Group 1-winning daughters from Invisible Coin and another classic victory for Tarzino, her Crown Oaks success adds a significant new chapter to one of the season’s notable staying families.
