Tim Nicholls stuck the boot into One Nation, Premier Annastacia Palaszczuk and Deputy Premier Jackie Trad in his pitch for the top Queensland job in a speech to LNP faithful in Brisbane on Sunday.

"Make no mistake, we will remind Queenslanders each and every day from now until the election of how Annastacia Palaszczuk and Labor are hitting and hurting families and businesses with these outrageous power prices," Mr Nicholls said.

"And you certainly can't create jobs or effectively manage our finances when the Queensland domestic economy is $6.5 billion smaller in 2017 than it was in 2015 when we were last in office."

In his address to LNP delegates from across the state on the last day of the LNP convention, Mr Nicholls said the LNP was the only conservative party they should vote for.
