Remains were found off Goolma Road in the outskirts of Gulgong about 11am, Saturday.

NSW Police have revealed a 55-year-old man and 37-year-old woman were inside the storage container.

An investigation is underway. Autopsies have been conducted and the deaths are being treated as "not suspicious."

CoreLogic shows the property is on Perseverance Lane, a small dirt track diverging from Goolma Road.

Aerial images supplied to Australian Community Media reveal six shipping containers and a caravan on site.

Officers were called to the property for a welfare check on Saturday when the grisly discovery was made.

"Inquiries continue into the circumstances surrounding the incident," a police statement said.

Anyone with further information about this incident is urged to contact Crime Stoppers on 1800 333 000.

A report will be prepared for the information of the coroner.
