According to The Guardian, Morrison was sworn in by Australian Governor-General Peter Cosgrove. Newly-elected deputy leader of the Liberal Party Josh Frydenberg was sworn in as treasurer, The Guardian reported.
Earlier in the day, the ruling Liberal Party elected Morrison as its leader to replace Turnbull in a secret snap election, thereby making the former treasurer the country's prime minister. Morrison secured his victory with 45 votes, while his opponent, former Home Affairs Minister Peter Dutton, got 40.
Fifty-year-old Morrison has held several positions in the country's government since the beginning of his political career. Before becoming treasurer in 2015, he served as immigration and border protection minister, and also social services minister.
