The two-leg tie had been scheduled for June 4 and 9 this year after the coronavirus pandemic forced its rescheduling twice, from dates in March and April.

With the Tokyo 2020 Olympics now also postponed until 2021 because of COVID-19, the matches have been scheduled for February 19 and 24.

"The latest decision was confirmed to allow both Member Associations to have sufficient preparation time considering the challenging and unprecedented circumstances brought about by the pandemic," the Asian Football Confederation (AFC) said.

In April, the playoff was "postponed indefinitely" before the June date was decided.

The winner of the tie will book their place at Tokyo 2020 and join Australia from the AFC region.
