Voice to Parliament is set for a No landslide as disastrous new poll for the Yes campaign emerges revealing support for the referendum has plummeted to a record low

The vote in Parliament will trigger a No landslide as the disastrous new Yes campaign poll emerges showing support for the referendum has fallen to a record low

Support for the Yes campaign has fallen to its lowest level yet, according to a new poll.

Just over a third of Australians (36 percent) say they will vote ‘Yes to the Voice to Parliament’, according to the Newspoll survey of 1,239 voters for The Australian.

It marks a drop of two points in the past three weeks – the lowest level yet for the beleaguered Yes campaign.

Meanwhile, opposition to the historic referendum has risen slightly to 56 percent, with less than three weeks until election day.

The shift to No is happening across most age groups and demographics, but most are among women and younger voters who previously were the strongest proponents of the Vote.

Support among women has fallen from 41 percent to 36 percent, but the share of those who say they would vote no has risen nine points to 57 percent.

Meanwhile, support for The Voice among men has risen by three percentage points to 36 percent, while among men with a university education there has also been an increase to 54 percent.

However, the biggest concern for the Yes campaign will be the decline in support among the 18 to 34 age group, which is the strongest base of support for The Voice.

Support among this demographic group has fallen five points to 50 percent – ​​down from 70 percent at the start of the year – while those who support No have risen four points to 41 percent.

Only 77 percent of 18- to 34-year-old voters said they were definitely or very likely to vote, meaning the age group most likely to vote yes was the least likely to vote.

But perhaps most painful for Prime Minister Anthony Albanese to read is that support for the Vote among Labor voters has also declined, with those who approve of the constitutional change falling from 61 percent in the previous Newspoll to 56 percent in the latest survey .

The poll also recorded a six-point drop in Liberal Leader Peter Dutton’s net approval rating since he took the job. It’s minus 20 now.

Mr Albanese’s improved slightly to plus three.
