Labor's chief tactician Tony Burke says he's planning to test the government's "unworkable", one-seat majority using the banking royal commission from the first day of the new parliament.
The government MPs who supported the idea of a banking royal commission going into the election campaign include George Christensen (left), Luke Hartsuyker, Ken O'Dowd (centre), and Warren Entsch (right).
In the upper house, Nationals senator John Williams has already promised he'll cross the floor on the issue if given the chance to vote.
The government has a one-seat majority in the house of representatives and Burke suggests it can be tested every sitting day by suspending standing orders during Question Time.
"Well, obviously the opposition can bring on a suspension of standing orders about the royal commission," said Burke.
The tactic – which cuts short Question Time, brings on a debate, and forces a vote – was used over and over again by Tony Abbott in 2010.
It was used to frustrate Labor's hung parliament for three years, but Burke insists this isn't revenge: "Trust me, this is not payback for 2010."
