Prime Minister Malcolm Turnbull will be under renewed leadership pressure with a new opinion poll showing the coalition's support crashing.

Labor has taken a 10-point lead over the coalition, with 55-45 on a two-party preferred basis, according to the Fairfax-Ipsos poll published on Monday

If an election were held last weekend, the government would have lost 24 seats.

The poll shows Mr Turnbull's personal approval rating has also dived to 40 per cent, but he still narrowly leads against opposition leader Bill Shorten as preferred prime minister.

The nationwide poll of 1400 people, conducted from Wednesday to Saturday last week, follows the West Australian Liberal party's disastrous state election result a fortnight ago.

A Newspoll in The Australian last Monday showed Labor leading the coalition 52-48 per cent on a two-party basis, with the coalition's primary vote rising three points to 37 per cent over the previous three weeks.

The Fairfax-Ipsos poll comes as there's talk of a reshuffle in the Turnbull government.

Deputy Liberal leader Julie Bishop on Sunday fully backed Mr Turnbull as a "can-do" prime minister who would take the coalition to the next election.

She said Mr Turnbull had her support and that of the "vast majority" of the party room to stay on as prime minister.

Mr Turnbull used poor opinion polls as his reasoning to challenge then prime minister Tony Abbott for the leadership.

Parliament resumes this week before breaking until the May 9 budget.
