Labor's shadow cabinet is expected to consider its approach to the Turnbull government's $6.1 billion omnibus savings bill as early as Thursday, amid continuing internal divisions about welfare cuts and surging voter support for minor parties in the Senate.

Labor has indicated it is keen to support as many of the nominated savings cuts as possible in the interests of budget consolidation, but has rejected the government's argument that all the cuts are ones that the opposition endorsed during the election campaign.

In particular, it argues some cuts were conditional on other measures and that they cannot be cherry picked.

Pauline Hanson and One Nation support has risen since the election.

Most contentious is a decision to end the payment of a clean energy supplement to welfare recipients.

Labor frontbencher Anthony Albanese has been leading the charge against accepting the cut, saying on the weekend it would affect the "most disadvantaged, the poorest in our community".
