The Grampians Trophy is a new addition to the WTA Tour in 2021. This tournament was created for players who had originally intended to participate in the 2021 Yarra Valley Classic or the 2021 Gippsland Trophy, but were forced to undergo strict quarantine measures upon arrival in Australia due to confirmed COVID-19 cases found on several of the chartered player flights to Australia.[1]
