Two Bathurst 1000 spectators have been banned from the event after two separate incidents involving a sex toy and porn videos.
Police were patrolling a camping site at Mount Panorama when they saw a man watching pornographic material on a television perched on a homemade trolley.
The 35-year-old was arrested and taken to an on-site police station where he was questioned and charged for displaying pornographic material.
After searching the man's tent, police discovered over 20 X-rated DVD's within his possession.
Following the incident, another man allegedly assaulted a policeman who was sitting in his patrol car.
The 22-year-old man has been accused of striking the police officer in the head with a dildo.
Both men have been bailed to appear at Bathurst Local Court on November 10.
