The preselection follows the announcement by Oxley MP and former Deputy Premier Andrew Stoner that he will retire at next year’s state election.

The three preselection candidates are Patrick Conaghan, Melinda Pavey and Adam Roberts.

None live in the electorate.

Out of the three candidates, Nationals MLC Melinda Pavey, has emerged as a leading contender.

“I have a proven track record in Parliament delivering for people in country NSW,” Mrs Pavey told The Macleay Argus.

"Being a good grass roots member is about listening and then delivering what the community needs.”

Adam Roberts has experience as a business owner, in social welfare, and in local government as a councillor and as deputy mayor of Port Macquarie-Hastings Council.

“I have a strong and diverse range of experience and skills across many sectors,” Mr Roberts said.

Patrick Conaghan was born and raised in Kempsey and served as a local police officer before becoming a solicitor.

“I have a great love for the electorate and want to see it thrive," he said.

"I know what the issues are, I know what needs to be done and I have determination to do it.”

All 400 NSW Nationals Oxley members who have been in the party for at least six months will have the chance to cast a ballot for their preferred candidate tomorrow.
