Brianna started in the sport when her mother enrolled her in Little Athletics as she had an interest in sport. It was prompted by Betty Cuthbert (who lived next to her Aunt) telling her she had sprinters calves.
She has always been a strong sprinter, alongside her speciality the short hurdles. At age 15 she was second at the national schools in a quick 100m time of 12.09w. During her 20s she steadily improved her PBs. There was major progress in 2015 when Brianna was 23. During that summer she brought her hurdles best down from 13.48 to 13.18. Her speed was impressive too running 11.63, which earned her a place in the Australian 4x100m relay team which competed at the IAAF World Relays.
Her momentum continued into the Olympic year. Over 100m she twice equalled her PB before revising it to 11.54. But she attacked the 100m hurdles with three improvements, 13.17, 13. 11 and 13.03 for second in the Australian Championships and now the sixth fastest in Australian history. Her new PB remained just 0.03 seconds short of a Rio Olympic qualifier. She chased the standard in Europe, but alas could not nail it. Back home for the 2017 domestic season, she was also very consistent, highlighted by a run of 13.06 and a slight wind-assisted 12.96 for second place at the nationals. She decided to not chase the 2017 IAAF World Championships standard and remain in Perth over winter and prepare for the 2018 Commonwealth Games season.
Her 2017/18 season started with a series of very quick 100s, 11.53w and 11.47w. Over the hurdles she was solid, until post Christmas when she ran a PB 13.02. Another few good runs, then at the Australian Championships and Commonwealth Games trials she ran 13.05 in the heat and managed 13.16 in the final to place third. She was selected in the Commonwealth Games team for the hurdles and 4x100m relay.
