This comes hard on the heels of a push by the England and Wales Cricket Board to have test cricket reduced from five to four days, although with extended hours of play.
Cricket Australia is portrayed as driving the test and one-day championship concepts. The test format would involve 100 points being allocated in every series, 60 going to the winner and the remainder reflecting individual test results. One day series would be limited to three games.
CA chief executive James Sutherland said: "I don't think people have quite cottoned on to how significant this is. Context is one thing but you're also creating structure in such a way that you no longer have games without meaning.
"They are all part of a league championship. There is a story, there is a narrative behind it all."
One of the effects would be wider interest beyond the countries involved for every series, because of the championship ramifications.
The new test and ODI leagues would bring an end to the current world ranking system, while nations could still arrange Twenty20 matches among themselves.
