The pilot reported that on arrival in the circuit area he observed that the employee responsible for inspecting the strip was in attendance, and there were no indications that the strip was unserviceable. After a normal approach and landing with 40 degrees of flap set, the nose was being held off when a bump was felt causing the pilot to believe that a failure had occurred with the nose gear. The pilot continued to hold the nose off until elevator control was lost. The nose then settled, and the propeller struck the runway. The nose gear had failed after striking a hole made by wild pigs, and the hole been obscured by weed growth. A further three holes that were not readily visible were found, but they were not in the landing path.
