Dates of MCG Test matches from 1970/71 season to 1982/83 season
In recent years rain has affected the SCG Test in January. i would like the MCG test to be moved to January [1st January to 5th January] no boxing Day test, the SCG Test move to December [20th December to 24th December] and call it the Christmas Test.
