LLEW O'Brien has protected former deputy prime minister Warren Truss's legacy winning Wide Bay for the LNP despite a projected 5.98% fall in the party's share of the vote.

Mr O'Brien, a former police officer, said his team had run a disciplined, positive campaign of which he was proud.

He said he would go into parliament determined to address Wide Bay's unemployment which was well above national averages and a major election issue.

Mr O'Brien is projected to receive 57.18% of the two-party preferred vote ahead of the ALP's Lucy Stanton who also stood for the seat in 2013. Ms Stanton received 42.82% of the two-party vote.

Mr O'Brien said while addressing unemployment would be a key focus of his first term he would also look to understand why Pauline Hanson's One Nation Party had polled so well.

"I'm a new MP with a lot of work ahead of me,'' he said.

With 43.06% of the vote counted from 53 of 62 polling places, Mr O'Brien has 40.92% of the vote, Ms Stanton 23.02% ahead of Elise Anne Cottam for the Pauline Hanson One Nation Party on 16.49%.

The Greens Bron Marsh secured 9.12%, Jannean Dean (Glenn Lazarus Party) 4.76%; Bruce Mayer (Family First) 2.89% and Barry Cook (KAP) 2.8%.
