AFL Women's career
Antonio was one of two marquee player signings announced by Fremantle in anticipation of the league's inaugural 2017 season. In January 2017, she was announced as the inaugural captain of the Fremantle AFL Women's team.[6]
Antonio was highlighted as "Player of the Week" by the AFL Players Association for her "best on ground" performance in the Dockers' first AFLW win in round 6 against Carlton.[7] However, she tore a quadriceps in the third quarter of that match, causing her to miss the final game of the season. After six rounds, Antonio was statistically in the top two players overall and in score assists, fourth in kicks, tackles and clearances,[8] and top ten in disposals and inside 50s.[7]
Despite missing the final game, Antonio was nominated by her teammates for the AFL Players' Most Valuable Player Award,[9] and was listed in the 2017 All-Australian team.[10]
Fremantle signed Antonio for the 2018 season during the trade period in May 2017.[11]
It was revealed Antonio signed on with the club for one year on 10 June 2021.[12]
