Tony Abbott was so hungry for power he was willing to do anything to form government after the election, one of the men who blocked his dream says.

Independent MP Tony Windsor says his discussions with Mr Abbott did deal with what do about climate change.

"Tony Abbott did say during those discussions that he would do anything to gain power," Mr Windsor told reporters on Tuesday.

The NSW MP said he presumed that applied to climate policy.

Asked for specifics, Mr Windsor was not keen to discuss confidential discussions.
