Federal Labor has retained a 51-49 lead over the coalition on a two-party preferred basis, according to the latest Newspoll.
The major parties haven't budged on a two-party basis for four Newspolls dating back to the beginning of July, the latest national survey published in The Australian on Sunday night reveals.
The fresh poll contains some additional bad news for Prime Minister Malcolm Turnbull.
The coalition's primary vote is down two points to 37 per cent while Mr Turnbull's lead over Labor leader Bill Shorten as preferred PM has been cut from 19 to 12 points.
The ALP's primary vote has fallen one percentage point to 35 per cent, the Newspoll suggests.
One Nation's primary vote has jumped two percentage point to nine per cent.
In the super Saturday by-elections on July 28 the coalition particularly struggled in the Queensland seat of Longman recording a primary vote of just 29.6 per cent while One Nation picked up 15.9 per cent of first preferences.
Labor's Susan Lamb retained the seat securing almost 40 per cent of the primary vote.
