Scott Morrison says his newly announced front bench is an election-winning team as the coalition tries to recover from last week's brutal leadership war.
He unveiled his first ministry at a press conference in Canberra late on Sunday, which included some new faces and new portfolios.
"The government 's ability is being restored and we are getting on with the job and tomorrow, Monday, when you go to work, we will be going to work, too," he said.
Leadership challenger Peter Dutton has been returned to cabinet in a revamped home affairs portfolio.
Mr Morrison is removing immigration and citizenship from the Home Affairs portfolio, giving those responsibilities to new minister David Coleman.
"We need a strong focus on our immigration program so it brings the skills and the harmony and the unity that we want from the program," Mr Morrison said.
"The minister for home affairs will focus on everything from cybersecurity to law enforcement to border of protection, security agencies, and will focus more principally on security tasks."
The new energy minister - or the "minister for reducing electricity prices" - is Angus Taylor.
"Angus Taylor has an incredible background working outside of this place and inside this place to solve complex and difficult problems," Mr Morrison said.
Alan Tudge will take on population and infrastructure, which Mr Morrison said was "one of the larger challenges that I know is burning in the minds and conversations of Australians."
"He will be the menace of the city, urban infrastructure, and population. Alan Tudge is the minister for congestion busting," Mr Morrison said.
