Remaining Asian Champions League group matches for East zone teams, including three A-League clubs, have been switched from Malaysia to Qatar.
The games, including remaining group matches, will now take place from November 18 to December 13 in Doha, which earlier this week saw the conclusion of West zone matches. Iran's Persepolis advanced to the December 19 final at an as-yet undecided venue.
East zone sides also hail from China, Japan, South Korea, Malaysia and Thailand.
The A-League sides involved in the ACL are Sydney FC, Melbourne Victory and Perth Glory.
Sky Blues coach Steve Corica said he was relieved the A-League title holders had finally been given some certainty about the restart of their ACL campaign.
"It's pleasing to now know where we'll be playing and when, and we're looking forward to the trip providing we get the right bio-security clearances and approvals," he said.
"We have unfinished business in Group H and the boys are really looking forward to getting stuck back in against the best in Asia.
"These games will also provide the perfect platform for our preparations of the new season as we look to defend our premiership and championship crowns."
Sitting in third place in their group, Sydney FC have four games remaining and they come up against the might of Shanghai SIPG, Jeonbuk Hyundai Motors and Yokohama F Marinos.
The Asian Champions League was suspended in March due to the COVID-19 pandemic.
West zone games were moved to Qatar where they resumed last month.
Despite stringent bio-security measures, several teams were affected by the novel coronavirus, with last year's winners Al Hilal axed from the competition after they reached the knockout phase with a game to spare.
The Saudi side had 30 players and staff infected by COVID-19 and were unable to field the minimum number of players required for their final group match.
