Wednesday morning's washout at Old Trafford deprived Australia a priceless opportunity to rehearse its lines for next year's ICC World Twenty20 in the Caribbean.
Although eight months remain before the next Twenty20 showpiece, Australia has only three international matches left before it takes on world champion Pakistan in its opening game at Gros Islet in May.
And, if its straight-sets exit at this year's tournament shows, it needs all the practice it can get.
It even took the drastic measure of fielding its Twenty20 side against Scotland in a 50-over game last week in a bid to give its players more time to gel.
Australia boasts only a modest record in the newest form of the game, winning only 11 of its 24 matches with one no-result.
"It is frustrating because we've got guys that we've flown over. We're trying to improve at Twenty 20 cricket and the more games we play the better for us," Clarke said.
"Like I said we're continually trying to do everything we can."
"I think we showed that in Scotland as well. We picked our Twenty20 team to play a one-day international against Scotland because we wanted to get as much cricket as possible together as a group."
"No doubt Twenty20 has become a huge part of cricket and it's certainly a huge priority for Australian cricket to get as much as Twenty20 cricket as possible together because we want to improve in this form of the game."
Australia is scheduled to play three matches at home in February, one against Pakistan at the MCG and two against the West Indies in Sydney and Hobart.
It will also play in an exhibition game against an ACA All*Star team at the Gabba in November to kick off the international summer.
