Queenslanders will be waiting until at least next week to discover the outcome of six lower house seats and, ultimately, who will govern Australia.
Based on current counting, the coalition holds 72 seats to Labor's 67, with four independents and one Green on the crossbench.
It is unlikely the LNP will claim the 76 seats it needs to form a majority government.
Of the several seats still up for grabs nationally, Herbert in North Queensland and Forde in the state's southeast separate the two major parties by just a handful of votes.
Queensland Labor campaign manager Evan Moorhead said he was "optimistic" the party would pick up Flynn, Capricornia and Longman.
Peter Dutton's electorate of Dickson in Brisbane's outer northwest is predicted to be held by the Liberals despite an almost six per cent swing against the immigration minister.
Griffith University political analyst Paul Williams said the result of the election would not be known for the next eight to 10 days, with the final negotiations to form a minority government expected to take weeks.
"For such a boring campaign it sure has produced some interesting results," Dr Williams said.
Dr Williams said the election showed Prime Minister Malcolm Turnbull became less appealing in Queensland the further away he got from the capital.
He said Labor's campaign on Medicare clearly bit in areas facing economic challenges like Herbert and Forde where jobs were at the top of the list.
"Words like innovation, smart industry and jobs for the future are good for Brisbane," he said.
"North Queensland hear the word innovation and become terrified because it means change, retraining, loss of jobs, loss of industry."
The fate of Queensland's twelfth Senate spot will also not be known for two to three weeks and could be taken out by Pauline Hanson's One Nation, the Greens or a third surprise party.
"We have no idea where the preferences are going," Dr Williams said.
He said with potentially three members in the Senate, One Nation's power would not be insignificant but the Greens and Nick Xenophon party would be the real powerbrokers.
He said most of One Nation's support had likely come from struggling people who were disenchanted, perhaps outraged, with the major parties, with only a minority voting on religious or racial issues.
"The current duopoly of Coles and Woolworths political parties doesn't seem to be working. Voters feel - try something else."
