PCB chairman Shaharyar Khan said that Australia had rejected their proposal to play three matches in four days or extend the series by a day to August 29 after all three preliminary games were affected by bad weather.
Just one, overs-reduced, match between India and Pakistan was played with both of Australia's games washed out.
"Australia said they could not ask their players to play three games in four days as it would be taxing on them," said Khan. "They also said they could not go for an extension in the event because they had scheduled warm up matches in England in the lead up to the ICC Champions trophy."
He said the proposal was suggested by officials of the Pakistan and Indian boards as the tournament broadcasters are reducing their guaranteed payments because of the lost matches.
"I can't say exactly how much we stand to lose out on. But if we also don't have the final than the guarantee money could be reduced considerably."
The broadcasters paid a reported $6 million for the rights.
Pakistan will meet Australia in the final on Saturday, with the forecast predicting fine weather.
