The royal fans walked down to the track to congratulate Christian. Also in attendance were Zara Tindall, her husband Mike and her brother Peter.

At one point, Sarah was seen putting a reassuring hand on Christian’s shoulder as they exchanged some words. Moments later, dad-of-two Christian gave Princess Eugenie, 33, a quick peck on the cheek.

Sarah, who travelled to Australia on Monday for the Global Citizen NOW, rocked a grey embroidered jacket over a floaty black midi dress while her daughter opted for a floral number, which boasted cold shoulders and ruched detailing. She teamed the look with plain white trainers and delicate gold hoop earrings.

Sarah, a devoted mother, seemed to be having a fantastic time interacting with the crew. The mother of two reportedly found out she was “free of cancer” last week.
Sarah has reportedly undergone more surgery to check her lymph nodes and the area surrounding the cancerous mole, according to the Daily Mail. Reporters were informed by a friend that medical professionals think the illness has not spread.
