Malcolm Turnbull will meet with his leadership team on Wednesday as a new poll shows a sharp drop in his personal popularity.
The prime minister will discuss the government's priorities with Nationals leader Barnaby Joyce, deputy Nationals leader Fiona Nash and deputy Liberal leader Julie Bishop in Canberra.
The meeting comes a day after National MPs and senators met to discuss a new coalition agreement and expectations for more ministers after picking up an extra MP at the July 2 election.
In the latest Essential poll, Mr Turnbull recorded a net approval rating of -11 per cent, an 11-point turnaround from two weeks ago.
His preferred prime minister rating of 39 per cent was the lowest recorded since taking over from Tony Abbott in September.

Labor leader Bill Shorten registered a 31 per cent preferred prime minister rating, with 30 per cent saying they did not know.
When asked how likely another election would be held within 12 months, 51 per cent of voters said it was likely while 28 per cent said not likely.
Mr Turnbull is set to have 76 MPs in the new parliament to Labor's 69, with five crossbenchers.
Two seats remain in doubt - Hindmarsh and Herbert - both of which have Labor ahead.
Asked what form of government they would prefer if a hung parliament was the outcome, the Essential poll found 36 per cent backed a Labor minority government with 33 per cent supporting a coalition minority government.
One in five voters said there should be a fresh election.
Mr Turnbull will decide on a reshuffled frontbench over coming days, having to replace as many as three ministers.
Mr Shorten is also expected to make some modest changes to the shadow ministry.
