Australia's new prime minister toured drought-hit farms Monday to show voters after a week of turmoil the government was back to work, but a leading opinion poll showed it now faces an even greater chance of electoral defeat after changing leaders.

Prime Minister Scott Morrison became Australia's sixth leader in less than a decade Friday after a faction of his Liberal party drove the ouster of Malcolm Turnbull but then failed to get its candidate elected leader.

The ruling Liberal-National coalition's primary vote dropped four points to 33 percent, a Newspoll showed, while the two-party-preferred split between the opposition Labor party and the coalition blew out from 51-49 in favor of Labor two weeks ago to 56-44, which would translate into a heavy election defeat.
