More than 3.6 million people have cast their ballots and now the counting begins to determine whether Labor will retain government or the Liberal National Party will swoop in.
Opposition Leader David Crisafulli was tipped to end the Labor government's nine-year reign after dominating polling early but Premier Steven Miles made up last-minute ground in public opinion.
A Courier Mail exit poll of 2000 voters acros the state revealed the LNP had won 33.9 per cent of the vote, with Labor narrowly on its heels with 33.6 per cent.
In Brisbane on Saturday, Mr Miles and his wife Kim cast their votes at Kallangur State School while Mr Crisafulli and his wife Tegan voted at Springwood State High School.
Mr Crisafulli spent the day visiting seats across the Gold Coast and Brisbane's north to spread the message that Queenslanders "deserve better than what you're getting".
Meanwhile, the incumbent premier has been fighting to win a term in his own right after taking over from Annastacia Palaszczuk after she resigned in late 2023.
Mr Miles wanted a chance to deliver on the promises that he had made to Queenslanders, he told reporters after his 36 seats in 36-hour blitz.

But the last ditch effort to convince voters may have been futile after nearly two million people cast their ballots early.
It wasn't all smooth sailing on polling day as Traeger MP Robbie Katter called in the lawyers over a corflute claiming the Katter's Australian Party did a deal with Labor.
"Lies and mudslinging are the refuge of the intellectually bankrupt – it's what you do when you have nothing else left," Mr Katter said of the LNP he accused of putting up the sign.
"If this is the way they intend on governing the state, it's a really poor sign."
The LNP is aiming to form its first government since Campbell Newman's 2012-2015 stint which paved the way for nine years of Labor.
Both leaders have campaigned hard on key election issues youth crime, housing, health and cost-of-living pressures.
But abortion emerged as a major talking point in the past fortnight after a crossbencher vowed to repeal the legislation if elected.

Abortion was decriminalised in Queensland in 2018.
Mr Crisafulli has been under enormous pressure in the past two weeks, repeatedly refusing to explain how he would guarantee abortion laws would not change.
It has coincided with the LNP's dip in the polls.
The latest Newspoll conducted for The Australian showed Mr Miles rated as a better premier at 45 per cent compared to 42 per cent for Mr Crisafulli.

But the LNP remained ahead on a two-party preferred basis at 52 to Labor's 47 per cent.
Labor has 51 seats and the LNP 35.
A party needs 47 seats for majority government.
