Opinion polls and confidence readings have swung behind Prime Minister Malcolm Turnbull - now even opposing politicians think the change is for the greater good.

Liberal Democratic Party senator David Leyonhjelm says there's a "lot more love in the air" at parliament house since the removal of Tony Abbott as Liberal leader a month ago.

Labor's Ed Husic concedes that from his own political perspective, the opposition would have preferred Mr Abbott was still PM.

"But the fact of the matter is the country is better that he's not," Mr Husic told Sky News on Sunday.
