Born in Barcaldine, Queensland in the central west, Denman moved 385 kilometres east to the mining town of Blackwater after her parents obtained work in the local coal industry.[1] Denman attended school in Blackwater.[1] After graduating from high school, she became an apprentice diesel mechanic.[1]
She began playing rugby league with the newly formed Blackwater Crushettes in 2015.[2] In 2016, she was named as Blackwater's Player of the Year.[1] Storch subsequently began playing for the Central Queensland Capras, coached by Alan McIndoe before Adrian Vowles selected her as a wildcard for the emerging Queensland women's side.[1]
In June, Denman represented Queensland Country at the Women's National Championships.[4] On 22 June, she made her debut for Queensland, coming off the bench in their 10–16 State of Origin loss to New South Wales.[5]
In May, Denman represented Queensland Country at the Women's National Championships.[9] On 6 October, Denman won her second NRLW premiership, coming off the bench in the Broncos' 30–6 Grand Final win over the Dragons.[10]
Less than two months after giving birth to her first child, Denman returned to the QRL Women's Premiership competition for the Capras, playing six games during the season.[14][15]
Denman continued playing for the Capras in 2023.[15] In May, it was announced she would be making her return to the NRLW after re-signing with the Brisbane Broncos.[17] On her re-signing with the team, coach Scott Prince said Denman had been playing great football for a long period of time and therefore deserved to be rewarded with another chance in the NRLW.[18]
