While there has been speculation Australians could head to the polls in the second half of next year, the prime minister hinted he wouldn't pull the trigger until 2022.

"I'm a full termer. Elections are too hard to win," he told the joint coalition party room in Canberra on Tuesday.

"I cherish every day. We'll do it for the time we said we would."

Mr Morrison said he was asked about election timing in March, when the coronavirus pandemic was sweeping the globe.

"It was the furthest thing from my mind then and it still is," he said.

The latest date for a simultaneous House of Representatives and half-Senate election is May 21, 2022 while the earliest is August 7 next year.

With the coalition maintaining a slight lead in most opinion polls, he urged MPs and senators to maintain discipline, unity and focus.

"In political cycles there's good times and bad times," Mr Morrison said.

"When things are going well that's when there's a risk of complacency and disunity, of the work rate dropping off."

Labor leader Anthony Albanese said the opposition was in "third gear" as he addressed the caucus room.

"Scott Morrison is addicted to announcements and retail politics but he's allergic to the hard work of national leadership and actual delivery," he said.

He said leaked government talking points showed the coalition's focus was on Labor even in budget week.
