The New South Wales Coroner has been told 22-year-old Gomeroi man Gordon Copeland ran from police into the flooding Gwydir River in the state's north-west during July last year.

The inquest heard a large-scale search for him was called off hours after he entered the water.

Inspector Helen McWilliam said a detective called her and instructed, "You can call the dogs off … there were two people in the car and they've been accounted for".

The coroner has heard the detectives had the wrong information, and Mr Copeland was still in the river.

Inspector McWilliam was on the verge of crying as she addressed the family at the inquest.

"And I believe this job will stay with both my young officers and myself for the rest of our lives."

She told the coroner she relied on volunteers to help search for Mr Copeland, and the town did not have enough emergency resources to sustain a large search in the following weeks.

"We don't have a large SES [State Emergency Service] unit here in Moree for example, nor a large RFS [Rural Fire Service] unit, so when it comes to — as we've learnt with this search — we don't have many resources locally that we can call on," Inspector McWilliam said.

"I really wish more people would volunteer for the RFS and the SES for the township of Moree, but we can only use resources that are available to us at the time."

Detectives advised calling off search

Detective Sergeant Greg Ryan admitted that if he had had more information from other officers, the search would not have been called off so soon.

He told the coroner he had not spoken to any of the officers who had seen Mr Copeland disappear in the Gwydir's floodwaters.

He said Detective Brad Beddoes and himself told officers to stop looking for someone in the river, after they got information only two people were in the car that night.

The inquest continues and is expected to finish at the end of the week.
