A great honour roll

That sort of resume makes him better than a few we call champions

Does anyone have his full record?

HUA and AJAX were by the same sire, the great HEROIC,  as were the Hall of Fame's HALL MARK and the brilliant nutcase NUFFIELD. 

HUA's third dam was the champion mare GLADSOME.

 He was a successful sire and his most celebrated son was the brilliant sprinter of the 1940's SAN DOMENICO.

Just to endorse Brian's recommendation of Kings of the Turf. This is an unmissable series on the AJC Derbies from 1860-1980 with so much thoroughly researched detail on the horses, jockeys, trainers and personalities, written in a professional and entertaining style https://kingsoftheturf.com/

The early 1930s racing scene, with much written on Phar Lap plus Jessica Owers' book  on Peter Pan, is well covered but the late 1930s is a racing era largely forgotten but who wouldn't want to read more about horses like the brilliant nutcase Nuffield, which is such an apt description. As Tontonan pointed out, Heroic was a champion racehorse and champion sire. It would be better placed in another thread, but Heroic along with Lonhro, Vain, Grand Flaneur and Chester would probably be the best performed champions on the track who later led the leading sire of the year list.

Avenger won the 1937 AJC Derby but disappointed after that with only 3 wins in total from 24 starts. The press accounts indicate the Derby distance was a little too far for Ajax but that Hua might have won but for being checked by Avenger inside the last furlong.

Trove really does make it easy to transport to earlier eras and indulge in nostalgia. Thanks for bringing up the forgotten Hua, Brian.

I'm not sure if it was from the time, JWH, but Nuffield was a really difficult to control horse and needed a rubber lined box to stop him doing himself damage.

A big man — 13 stone (83 kg) in cycle-racing trim — Kellow was enormously energetic, personally popular and commercially audacious to the point of illegality. In 1910 he was fined £1980 by the High Court of Australia for manipulating invoices to evade customs duty. In his forties he looked for opportunities to diversify his interests and expand his wealth and found them in the traditional Australian fields of sheep-grazing and horse-racing. While continuing to develop his motor business, he invested in Gundaline, a Riverina sheep-station to which he travelled by private plane in later life, and also in Hall Mark, Heroic, Nuffield and many less notable gallopers, trained by Jack (Michael) Holt. Hall Mark won the 1933 Melbourne Cup, Heroic justified the very high price of 16,000 guineas Kellow paid for him in 1925 by winning more than twice that amount, while Nuffield won the Sydney and Melbourne Derbys in 1938.

Peter Riddle was, as Harry Telford was to Phar Lap, the man that created the racehorse Shannon. Born in country Victoria on 26 July 1884, Riddle was the son of a trotting driver, and as such was instilled with horsemanship from the earliest age. Like his father, he became a premiership-winning driver in New South Wales and New Zealand until he took up flat training in 1927. A tender hand with a horse, he met only moderate success in Sydney before buying Shannon in 1943. The bay horse became the centre of his life, and though seriously ill, Riddle never compromised Shannon's welfare. Kind, gently spoken, relatively tall and thin, the ailing trainer was one of Randwick's gentle creatures. When he eventually passed away on 29 June 1947, Shannon was the only horse in his yard (Jessica Owers)
