Cape Town - Cricket Australia chief executive Kevin Roberts says he remains open to the possibility of playing four-day Test matches in the future.
The first-ever four-day Test took place between South Africa and Zimbabwe last December, with the Proteas emerging victorious inside two days.
Australia have no immediate plans to stage their own four-day Test match, but Roberts says they are open to giving it a try.
"There's a bit to be said for it," Roberts told SEN. "It's certainly something we need to be open minded to down the track.
"The average duration of a Test match is a shade over four days.
"We know there's been timeless Tests over the years, we know there were even three-day Tests. So Test cricket hasn't been five days in duration forever.
"And I think the concepts of four days going forward is something we need to be open to, without jumping to conclusions."
Roberts said a match between Australia and Afghanistan set for November 2020, which falls outside of the Test Championship, could be used as a trial for four-day Test cricket.
