Encouraged by crucial by-election victories, Labor leader Bill Shorten is increasing the pressure on Malcolm Turnbull to dump his planned corporate tax cuts and quit as prime minister.

The result has also sparked talk among Coalition frontbenchers of a policy rethink on the tax cuts.

Independents Tim Storer and Derryn Hinch say they're both open to negotiation but will still oppose the Coalition's plan to cut taxes for big businesses.

So far just four of the 10 crossbench senators have promised to support the government on the matter.
