Despite the triumph, Eva battled to cut through in the male-dominated riding ranks following that day.
The family believes the controversy over allowing a female to ride in the race in Bundaberg hindered any hopes of a career in the saddle.
“She was an unregistered jockey so she ran in amateur races but that was the only registered race she got to run in,” Sue said.
“She did try to get registered after that but for some reason, we don’t know why, but they refused her registration, maybe because of the uproar from her winning.
“A lot of the news articles said she would have to go on thinking that she should have been born a male rather than a female, but maybe she was just born in the wrong era.”
Eva later married Brisbane trainer Barney King, riding trackwork for the stable and racing at Kedron, Strathpine, and Coorparoo.
In 1925, Eva rode as an amateur at Springsure, south of Emerald - achieving three wins, three seconds, and two thirds in four days of racing.
Following the closure of unregistered racing, King became a licensed trainer with the Queensland Turf Club.
Although Eva couldn't be licensed, she assisted as the King stable won major races, including the 1934 and 1935 Stradbroke Handicaps with Petrol Lager, and several other notable races with Brown Force.
Sadly, she died in 1952.
