Luke Cann was one of Australia’s best junior javelin throwers, placing second at the 2011 IAAF World Youth (U18) championships and seventh the following year at the World Juniors. In 2013 he broke the national under-20 record with a distance of 76.58m. In his first year as a senior (2014) he set four PBs including when placing third in the Australian Championships/CG trials and in the qualifying round at the Glasgow Commonwealth Games. He placed seventh in the final. In June 2016 in Townsville he became just the 11th Australian to throw over 80 metres. In 2017 he raised his best to 81.07m again mid-year in Townsville.
In a thrilling competition at the 2018 nationals/Commonwealth Games trials, Luke placed fifth (fourth Australian) and a week later was announced in the Australian team for the Games.
Born and raised in the outer Melbourne suburb of Frankston, Luke moved to Perth for coaching. He has deferred his university studies in Secondary Health and Physical Education
