The Liberals and One Nation agreed to exchange preferences, with One Nation helping the Liberals in Legislative Assembly seats and the Liberals reciprocating in the Legislative Council.
"I think we've got to stick with what I've always said, we're not there to shore up anyone in the Parliament, and I think voters should have the opportunity to pass their preferences where they want to go", she said.
Senator Hanson insisted the media was covering up the extent of the One Nation vote, saying her party had already picked up three seats, and "possibly another two".
But as soon as One Nation cut a deal with the Liberals, its loyal followers jumped off the bandwagon, because Pauline Hanson's party underestimated how much it would rankle people.
QUT political science Professor Clive Bean said while the party would be disappointed with that result, Queensland remains a strong state for One Nation, and it couldn't be written off for the upcoming Queensland election.
With 67 per cent of the vote counting on Saturday night, One Nation's primary vote was a dismal 4.7 per cent.
In a sign Mr Morrison backs Malcolm Turnbull's view that future preference deal should not be ruled out, he said the Liberal Party lost on Saturday because of the flagging state economy and its long time in power. Weeks later, Newspoll forecast the party's vote had slumped to 8 per cent, in the wake of Senator Hanson's controversial statements questioning vaccinations and praising Russian president Vladimir Putin.

The surge of One Nation was happening because voters were feeling disenfranchised and fed up with the two major political parties.
Ms Hanson said the One Nation campaign was "rushed" and some disgruntled candidates had caused "havoc" during the campaign.
The Australian reports Turnbull is refusing to dismiss a similar preference deal with One Nation in the next federal election despite Deputy Leader Barnaby Joyce calling the idea a "mistake".
"All the imbroglio with regards to preferences means people start to over-assess and exaggerate what they think the support is of their new partner and they also just confuse their constituencies", he said.
The result will also see mining giants Rio Tinto and BHP Billiton escape a state tax on their iron ore businesses proposed by the rural-centric National Party, which fell short of obtaining the influence to force such a measure.
