Organisers said safety was their main consideration in cancelling the Melbourne event for men and women, a traditional tune-up played in the week before the Australian Open Grand Slam in January.
"We've made the big decision to push the pause button on the Kooyong Classic for 2021," they said in a statement, adding: "Covid-19 is presenting so many challenges for the whole community.
"With everyone's safety first and foremost in mind, and still so much uncertainty over the outlook for the rest of 2020 and beyond, we feel that this is the right thing to do."
