SMH reports that Tony Abbott said the following about Rudd's "on-air apology during a television interview on Sunday for the government's home insulation scheme and for his own delay over an election promise to reform the public hospital system".

"I think he looked just rattled" said Abbott

Now what did the former member for Bennelong say about getting cocky?

"Don't you come in here with your puffed-up hubris and start lecturing this side of the House about accountability under the Westminster system,"

And:

"There is a long way to go before there is a decision to be made by your master and mine, and that is the Australian people."
