After a strong junior career where she made the 800m semi and 1500m final at the 2006 IAAF World Junior Championships, Zoe took some years to transition to the national senior team.
In 2012 she was a semi-finalist in the 1500m at the London Olympics and a year later created Australian history as the first ever 1500m finalist at the 2013 IAAF World Championships, placing seventh. After competing at the 2014 Commonwealth Games, she again made the Olympic semi-final at Rio 2016. She launched 2017 with silver in the highly competitive national 1500m championships. In April she won a bronze medal in the Australian 4x800m relay at the IAAF World Relays. Selected for the 2017 IAAF World Championships in the 1500m she continued her splendid global championship record. In her semi-final, she missed qualification for the final by one place and just 0.18 seconds.
In a quick 2018 national 1500m championship final, the three-time champion ran strongly to place a close second to Linden Hall in 4:08.15 and achieved automatic nomination for the Commonwealth Games.
She has a Bachelor of Humanities from the University of Oregon, having lived and studied there for four years, and a Postgraduate Diploma in Psychology from Deakin University.
