Ahead of Monday's rollout of the COVID-19 vaccine, a Newspoll published by The Australian newspaper shows Mr Morrison bolstering his approval and extending his lead as preferred prime minister over Anthony Albanese.

While scrutiny of the government has been intense during the fallout from the alleged 2019 rape of defence ministry staffer Brittany Higgins, the coalition's primary vote remains unchanged at 42 per cent in the poll.

In a potential blow to his prospects as opposition leader, Mr Albanese recorded among his worst approval ratings since winning the job after Bill Shorten resigned in 2019.

Mr Albanese's satisfaction levels fell three points to 38 per cent and his dissatisfaction rating rose to 45 per cent.

His fall in support came despite a one-point primary vote lift for Labor to 37 per cent, the party's equal-best result in more than a year.

The poll showed the two-party-preferred split remains unchanged at 50-50 and approval of Mr Morrison's performance rose a point to 64 per cent.

Asked who would make a better prime minister if an election was called, Mr Morrison scored 61 per cent, while Mr Albanese only rated 26 per cent.

Popular support for Pauline Hanson's One Nation remains steady at 3 per cent, according to the poll, while support for other minor parties fell a point to 8 per cent.
