Former prime minister Scott Morrison has been sworn in to parliament as his successor records a solid start in the first Newspoll since the May federal election.
Mr Morrison missed the first week of the 47th parliament to attend an international leaders' event in Tokyo.
He pledged his allegiance to the Queen on Monday alongside former deputy prime minister Barnaby Joyce and Labor MP Maria Vamvakinou who were also absent from the opening of parliament.
Mr Morrison is seated on the backbench for the first time in nine years after resigning from the leadership of the Liberal Party following the May federal election loss.
In the upper house, Greens senator Lidia Thorpe drew the ire of opposition benches after branding the Queen a "coloniser" while reciting the oath of allegiance.
Meanwhile, Prime Minister Anthony Albanese is off to a strong start in the first Newspoll since Labor won office.
His voter satisfaction rating is at 61 per cent, the poll published in The Australian on Monday shows.
This is the highest number recorded for a post-election Newspoll for a new prime minister since the satisfaction measure started in 1985.
Mr Albanese is also ahead on the preferred prime minister measure, at 59 per cent versus 25 per cent for Opposition Leader Peter Dutton.
On a two-party preferred basis, Labor is ahead at 56 per cent compared to 44 per cent for the Liberal-National coalition.
Labor's primary vote has lifted to 37 per cent, from 32.6 per cent at the May 21 election, against 33 per cent for the coalition.
The Greens were tracking at 12 per cent, while the teal independents were on 10 per cent.
Independent Tasmanian senator Jacqui Lambie said Mr Albanese wasn't just in a honeymoon period.
"He is still doing the wedding waltz," she told Nine Network on Monday.
But she warned there were challenges ahead, particularly on the cost of living.
"There will be a fair bit of pressure on him over the next six months," she said.
"Living standards out there are tough, people are doing it really tough, so let's see how it goes."
The Newspoll of 1508 voters was conducted between July 27-30.
Parliament sits for four days this week before taking a four-week break.
