The Queensland election result is headed for the courts, with the Electoral Commission planning to refer the seat of Ferny Grove to the Court of Disputed Returns.

It will then determine whether to order a by-election, because a candidate there was disqualified.

Both leaders were still in election campaign mode on Sunday.

Labor leader Annastacia Palaszczuk was on the pseudo-hustings at Brisbane's South Bank markets, while the new LNP leader, Lawrence Springborg, took his campaign to an ambulance station where he stressed he was still in government.

"The caretaker conventions allow for the day-to-day business of government to continue," Mr Springborg said.

And it seems he wants to stay in caretaker mode for a lot longer, using the threat of a by-election in Ferny Grove to keep things as they are.

"I think we need to be very much focused on the caretaker government doing its job in Queensland until we get a clear direction in what may happen in Ferny Grove, because I don't think people would be wanting things to change and then change back the other way, whatever the outcome may be," he said.

Mr Springborg pointed to the 1996 Mundingburra by-election, which saw the Goss Labor government replaced by a minority Borbidge Coalition government months after a general election.

"I think everyone should just hold their horses until we get a clearer understanding," he said.

Ms Palaszczuk said she would not "deal with hypotheticals".

"The Electoral Commission will make their determination in regards to Ferny Grove," she said.

Commission to soon finalise counts for other seats in doubt

Electoral Commission Queensland has taken legal advice about Ferny Grove and says it will issue a writ for the seat once counting is finalised.

That means whoever wins that electorate will take their place in Parliament, but then the result will go to court.

The Electoral Commission wants the Court of Disputed Returns to decide whether a by-election is warranted considering the disqualification of the Palmer United Party candidate, Mark Taverner, who is an undischarged bankrupt.

"The validity of the Ferny Grove election and any consequences arising if it were determined to be invalid are matters which are decided by the Court of Disputed Returns, not the Commission," the Commission said in a statement.

"The existence of a candidate who is a disqualified person and who receives votes for an election raises an issue concerning the validity of the result which must be resolved by the Court of Disputed Returns.

"For these reasons, immediately the writ is returned, the Commission will refer the election in Ferny Grove to the Court of Disputed Returns for it to determine the validity of the Ferny Grove election and, if it is invalid, to decide what consequences arise, which possibly includes a by-election."

As for the other seats in doubt, the Commission will finalise counting after Tuesday's deadline for postal votes.
