A man has allegedly been caught with two unregistered guns, two bayonets and 16 cannabis plants estimated to be worth about $32,000.

The 59-year-old was arrested on Friday afternoon after the search of a home on the NSW south coast, where police say a revolver and a .22 calibre pistol, both unregistered, were found along with the drugs and other weapons.

The man has been charged with a number of firearms and drug offences and is due before Narooma Local Court in April.
