It comes after sitting member Hugh Delahunty announced on February 9 he would retire at this  year’s state election.

Ms Kealy said she was excited to throw her hat into the ring.

"I have a strong belief in the abilities and resourcefulness of people in the Lowan electorate," she said.

"We know how to get things done out here, and I respect the sense of resilience and innovation that communities and businesses show. 

"I would love the opportunity to support and encourage people in the Lowan electorate to realise their full potential, as individuals, businesses and communities."

Ms Kealy said improvements to road and rail infrastructure, reducing the burden of red-tape on business, access to technology including mobile phone coverage and decentralisation of government services were the key issues she would pursue. 

"I feel that, as a member of the next generation of Nationals, I can make a difference in representing the people of Lowan," she said. 

Ms Kealy, who has a one-year-old son Harvey, said her social worker husband, Tim O'Donnell, was 100 per cent supportive of her decision.

"Like many modern families, Tim and I share child-raising duties and both feel that representing the Lowan electorate would be a great way that we, as a family, can contribute to the future of our region," she said. 

Ms Kealy will join Haven resident Russell McKenzie and Horsham football administrator Bruce Petering, who are also seeking pre-selection.
