Head coach Andrew McDonald will miss the start of Australia's tour of Sri Lanka after testing positive for coronavirus.

McDonald was unable to fly out with the rest of the touring party on Wednesday after returning a positive test on Tuesday.

Michael Di Venuto will coach the Twenty20 team in the absence of McDonald, who must spend a week in isolation.

A three-match T20 series gets under way in Colombo next Tuesday.

Sri Lanka and Australia will then play five ODIs this month before a two-match Test series in Galle.

Australia have not been in action since McDonald was appointed as Justin Langer's successor on a four-year deal.
