Australian Prime Minister Scott Morrison has admitted loss in the national polls on Saturday following a "difficult night" for his government, reports ndtv.com.

"Tonight I have spoken to the leader of the Opposition and the incoming prime minister, Anthony Albanese, and I have congratulated him on his election victory," Morrison was quoted.

Morrison (54) observed that voter support for major parties had fallen in the polls.

"I think about the upheaval that is taking place in our nation, and I think it is important for our nation to heal and to move forward," he added.

"I have no doubt under strong leadership of our coalition, three years from now I am looking forward to the return of a coalition government," an emotional Morrison said.
