The LNP says it will lift the payroll tax threshold for businesses by $25,000 a year for ten years, and will aim to create 500,000 jobs.
The Opposition wants the current payroll tax threshold of $1.1 million to increase by $250,000 to $1.35 million in a decade, at a cost to the budget of $100 million across the first four years.
LNP Leader Tim Nicholls said 14,000 businesses would benefit in the first year.
"Many small to medium businesses aren't hiring more Queenslanders, to sit under the threshold and avoid paying payroll tax," Mr Nicholls said.
At a hardware store in the marginal Labor seat of Springwood, the LNP released an economic plan which Mr Nicholls said included lower taxes, new infrastructure and cheaper electricity, to create half a million jobs in ten years.
"Lowering taxes for families and businesses is at the core of the LNP's economic plan," he said.
"If businesses are weighed down by increasing costs they can't grow and won't employ more Queenslanders."
It was the party's first major policy announcement of the election campaign.
Mr Nicholls later visited a quarry in the marginal LNP seat of Lockyer — a target of the One Nation party — which only narrowly made it under a rail bridge at the town of Grantham.
He also hit back at Premier Annastacia Palaszczuk, who twice today said Mr Nicholls could not be trusted.
"Welcome to day two, we're getting straight into hope and optimism," he said.
"Let's not have a 'fear and smear and no idea' campaign."
Labor pledges to hire more nurses
Meanwhile, Labor has pledged to retain frontline services, by spending $110 million on recruiting 4,000 graduate nurses over four years.
It also plans to hire 100 new midwives at a cost of $57 million over four years, and employ 400 people under the Nurse Navigators program at a cost of and $72 million each year.
The Nurse Navigator program caters for patients with complex health problems that require specialist care.
It is understood the promise was already part of the forward estimates budget.
Annastacia Palaszczuk and Health Minister Cameron Dick met with staff at the Proserpine Hospital for the announcement.
"We are making this genuine commitment now to continue the rollout of those graduate nurses for example — we promised that — 1,000 a year," said Mr Dick.
"The nurse navigators will make a big difference and the 100 midwives … will also make a very big difference. They will be employed across all of our hospital and health services."
