Tennis’ top stars will quarantine in Adelaide rather than Melbourne and play an exhibition there ahead of the Australian Open, with the city also hosting a WTA event after the years’ first Grand Slam, organisers said Saturday. Some 1,270 players and support staff are due to arrive in Melbourne on charter flights late next week, where they will have to spend a mandatory 14 days in quarantine. But with hotel rooms in the city scarce, Australian Open chief Craig Tiley said he had approached the South Australian government about taking some of them. Matters were further complicated when a hotel in Melbourne that was due to accommodate players pulled out on Tuesday, reportedly because of concerns from residents.
