A father and son who were due to face court earlier this week on drugs and firearms charges are identified as two of the three people found dead at a rural property near Nyngan in central New South Wales.

Emergency services were called to a property at Hermidale just after 8:30am on Friday when a member of the public found a man dead in the driveway.

Police from Darling River Local Area Command were called and found another man and woman dead on the property.

One of the bodies was located inside a caravan that had been damaged by fire.

The ABC has been told father and son Stephen and Jacob Cumberland are two of the deceased.

Both men were due to face court earlier this week on firearms and drugs charges after a raid on a property in October last year.

The property is being examined by specialist forensic officers and detective are appealing for anyone with information to come forward.

Acting Local Area Commander for Darling River Andrew Hurst said a strike force had been set up into the deaths, which were described as "suspicious".

"The alarm was raised by a witness to the ambulance service and they notified police which in turn caused our deployment this morning," Inspector Hurst said.

"Upon arrival, police located three deceased persons on the property, a crime scene was established and now a strike force has been formed.

"Police are treating the deaths as suspicious and we're seeking information from the public."

Inspector Hurst would not confirm whether the deaths were related to drugs and weapons.

"At this stage we have no information to indicate that is the case," he said.

"The scene is now being processed by forensic police and we expect that the processing of the scene will be completed by tomorrow."

Inspector Hurst also said he was unable to release information about how the three people had died.

"At this stage we can't release any information about the manner of the deaths for operational reasons," he said.

Inspector Hurst said he was receiving assistance from other commands in the area and they were assisting the strike force in conjunction with the Darling River detectives.

"We're treating the matter very seriously and we're putting as many specialist police as we can into this investigation immediately," he said.

"It's a tragic incident. The western region is populated by remote localities and small townships.

"These incidents in small communities are felt more broadly and our thoughts go out to the families of the three persons involved."

Hermidale is just over 200 kilometres north-west of Dubbo and was last recorded as having a population of 131 people.

According to the Hermidale Public School website, the hub of the town is the small school, which has 10 children enrolled, the Country Women's Association, post office and the Hermidale Hotel.

Hermidale is a big farming community with the main produce being wool, cattle and cropping, the website said.

The Mayor of Bogan Shire, which covers Hermidale, said the community would band together in such distressing times.

"I don't think the people who are deceased have been residents there very long," Cr Ray Donald said.

"But nevertheless I'm sure the community would give any support they could to any friends or relatives of those people that have been involved in this tragic accident."
