Over 70 guns found in NSW 'hunting room'

An enormous cache of unregistered and illegally-stored guns has been seized from a home in the New England region of NSW.

The property at Tenterfield was raided by NSW Police officers on Wednesday morning and was found to contain 73 long arms, a .22 calibre bolt-action pistol and a replica revolver.

The search warrant related to a Queensland Police investigation and also turned up 200 rounds of ammunition.

"None of the firearms are believed to be registered and (were) not being safely stored," Queensland Police said in a statement.

Police photographs show the rifles hung on wooden racks on all sides of an apparent hunting room, which is also decorated with mounted antlers and animal skins on the floor.

A 67-year-old man has been interviewed and had his gun licence suspended.
