Australia coach John Buchanan has warned against increasing the number of international Twenty20 matches.
England and Australia kick off the Ashes summer with a Twenty20 match at the Rose Bowl on Monday.
"I think its real value lies in junior cricket. Also it targets a different audience, being shorter," he said.
"From those perspectives I think it's of value but from increasing the amount of international cricket I don't."
Australia played the first ever such match against New Zealand in February and will also feature in the first match on English soil.
Following its success in county cricket, the shorter format has already transferred successfully to domestic cricket in South Africa and Pakistan.
Australia will also hold a tournament between state sides next season but the International Cricket Council has so far resisted incorporating it into the calendar on a full-time basis.
The volume of international cricket has been blamed for player burnout in the last five years.
And Australia are already set to play 10 one-day internationals and five Tests on their four-month Ashes tour.
Buchanan's side opened the trip with a Twenty20 victory over a PCA Masters XI in front of a packed crowd at Arundel on Thursday.
Skipper Ricky Ponting is a fan of the shortest form of the game and believes it can actually improve the skills of his world champion side.
He said: "If you look at what one-day cricket has done to Test cricket over the years, it has made it a more skilful game and it's a result, I think, of the amount of one-day cricket guys are playing around the world.
"I think this Twenty20 game could actually have an effect on the one-day game in the same way.
"Guys know they can play their shots from ball one and get away with it and do it well on the batting side of things.
"Bowlers have to adjust a lot more, a lot quicker and think on their feet through their bowling spells, so hopefully we will see some of that transfer across to the 50-over game.
"One-day scores in general have increased over the last few years quite a bit; whereas 220 or 230 used to be a good score in one-dayers now 320 or 330 is a very good score.
"And to score 350 in a day in Test cricket is not unusual and I put that down the amount of one-day cricket that is played."
