Support for an Indigenous Voice has slipped to its lowest level in the latest Newspoll, while its key opponent – Opposition Leader Peter Dutton – has suffered a similar fate.

The online survey of 1239 voters between September 18- 22 for The Australian newspaper found only 36 per cent intended to vote Yes on October 14.

This equates to a two-point fall in three weeks and means support for an Indigenous Voice to Parliament has fallen to its lowest level.

Opposition to the Voice has increased to 56 per cent less than three weeks before voters have their say.

Despite the No case looking to hold an unassailable lead, the fortunes of Dutton are headed in the opposite direction.

Dutton’s personal approval ratings fell six points to a record low of 32 per cent – the lowest since he became Liberal leader after the May 2022 election.

His net approval rating is now at minus 20.

On the leader who voters considered the better prime minister, the numbers were mostly unchanged with Anthony Albanese on 50 per cent and Dutton falling one point to 30 per cent.

The swing to the No camp has occurred across almost age groups and demographics but is most significant among women and younger voters.

Women who said they would vote No lifted nine points to 57 per cent, while those voting Yes fell five points to 36 per cent.

Support within the 18-to-34-year-old demographic, who are considered the strongest advocates for the Voice, has ­fallen five points to 50 per cent after being close to 70 per cent at the beginning of the year.

It also declined in the 35-to-49-year-old age group (down three points to 36 per cent).

On the upside, support among males increased three points to 36 per cent and also rose among university-educated voters, up five points to 54 per cent.

Interestingly, the survey showed only 8 per cent of voters don’t yet know which way they will vote – down one point.

Support for government

Support for Albanese, who on Sunday invited the Coalition to establish a joint parliamentary committee to oversee the creation of the advisory body, improved slightly to 47 per cent.

But he also remained at historically low levels with a net approval rating of plus three.

Despite the Coalition (down 1 per cent) and Labor (up 1 per cent) each sharing a primary vote of 36 per cent, support for the government increased two points to a 54-46 lead on a two-party-preferred basis.

Minor parties and independents increased three points to 11 per cent, the Greens fell two points to 11 per cent, and Pauline Hanson’s One Nation dropped to 6 per cent.
