Prime Minister Scott Morrison has ended the year on a high note by extending the coalition's lead over Labor in the latest Newspoll.

The last Newspoll of the year shows the coalition leads Labor 52 per cent to 48 on a two-party-preferred basis, compared with 51 per cent to 49 a fortnight ago.

Support for the coalition has gone up one per cent to 42 per cent while Labor's primary vote is unchanged on 38 per cent.

The poll follows the last sitting fortnight of parliament where the government was unable to get its union-busting legislation passed and the prime minister was under pressure on Energy Minister Angus Taylor, who is being investigated over forged documents on the Sydney mayor's travel spend.

However, the government was able to repeal the medevac law that was passed before the election.

Mr Morrison remains the preferred prime minister, with a two-point lift in his personal satisfaction rating to 45 per cent, but Opposition Leader Anthony Albanese enjoyed a similar lift, The Australian reports.
