The coalition was unable to swing a winning number of votes in Saturday's by-elections but support for Bill Shorten hasn't been boosted by Labor's victories, the latest Newspoll shows.
The poll, published by News Corp Australia on Sunday, shows the coalition gaining a point to secure 39 per cent of the primary vote compared to Labor's 36 per cent.
However when it comes to two-party-preferred, only 49 per cent of people would vote for the coalition compared to 51 per cent for Labor.
Leadership dissatisfaction with Mr Shorten rose one point and approval for Prime Minister Malcolm Turnbull rose by the same amount.
The support for Turnbull comes despite Labor recording favourable swings in four of the five by-elections on Saturday.
The preferred prime minister remains unchanged since the last Newspoll a fortnight ago - Mr Turnbull leads Mr Shorten 48 to 29 per cent.
The national poll of 1704 voters was conducted between July 26 and July 29. It's the 37th consecutive Newspoll in which the coalition has trailed Labor on a two-party preferred vote.
