In the latest news, cricket Australia have cancelled the Australian tour of South Africa due to the virus and the concerns about the new virus strain. They offered for South Africa to come play in Australia but they knocked it back which is understandable. I'm sure something could be worked out like we have been seeing with other series going on.
South Africa is going through a very bad phase right now, with increasing number of infections and deaths, so the reluctance from the part of the Australian side to tour that country is perfectly justifiable. The South Africans are not very happy about it, and understandably so. The Australian tour was their chance of getting the finances back on track, and now that is gone as well. They have the option of traveling to Australia, but then the TV rights will stay with CA rather than CSA.
@Sithara007 it’s a sad decision for cricket fans because I was really looking forward to this series, but sadly one cannot do anything about it. Another option for them was to host the series in Dubai like Pakistan did, and then split the revenue with each other.
