King's victory in the $3 million Caulfield Guineas (1600 metres) at the weekend thrust her into the spotlight for the upcoming Cox Plate, to be staged at Flemington for the first time. If she wins, King would follow Michelle Payne and Jamie Melham into racing folklore as one of the sport's trailblazers.
King arrived in Australia from the United Kingdom on a working holiday in 2014 and has since formed a formidable partnership with flamboyant Sydney-based New Zealand trainer Bjorn Baker. The pair combined to win the Guineas on well-backed favourite Warwoven, delighting Melbourne racing fans.
No woman has previously won the Cox Plate, Australia's premier weight-for-age race. Payne famously broke the glass ceiling in the Melbourne Cup, while Melham has also achieved notable firsts for female jockeys. King's Caulfield Guineas win marks another milestone, and attention now turns to whether she can go one better in the Cox Plate.
