Opinion polls suggested that the conservative coalition led by the Liberal Party would lose, but after a few hours, they headed for victory.
Australian Labour Party Opposition Leader Bill Shorten admitted defeat in the country’s elections.
Mr. Shorten told supporters in Melbourne: “without wanting to maintain any false hope, while there are still millions of votes to be counted and important seats to be finished, it is obvious that the Labour Party will not be able to form the next government.”
The exit polls had favored the Labor Party, but, in spite of the significant developments in New South Wales and Victoria, the attempt to Shorten becoming the sixth prime minister of Australia in six years fell short.
With more than half the votes counted, the coalition government was heading for a surprise victory, although it is not yet clear whether it can govern with an absolute majority.
By Saturday night, the Liberal-National Coalition had won 74 escudos in the lower house of 151 seats, 65 of them to the Labor Party and 12 undecideds, according to the Australian Broadcasting Corp.
A total of 76 seats are required to form a majority government.
Mr. Morrison campaigned on the tax cuts to income and the risk to the economy posed by the Labour Party, and his party made important gains in the states of Queensland and Tasmania on the way to victory.
