A federal spill of liberal leaders has done nothing to return voters to the party with the Labor coalition behind the 40th Newspoll in a row.
The coalition is behind Labor by 44 to 56 in a two-part preferred vote in the latest Newspoll published in The Australian on Sunday night.
It is the Labor's strongest primary vote since Kevin Rudd after his ouster as prime minister in July 2010, reports The Australian.
Scott Morrison leads as the preferred prime minister over Labor Bill Shorten by 42 to 36 percent, according to the poll of 1653 voters, which took place between September 6 and 9.
Mr. Morrison was installed as prime minister on August 24 after a leadership spill saw Malcolm Turnbull expelled from the main office.
More than 40 percent of voters were satisfied with Mr. Morrison's performance, while 39 percent were dissatisfied, the survey showed.
This compares with Mr. Shorten's performance, which was rated by voters with a dissatisfaction of 51% and satisfaction of 37%.
