About 1500 police officers patrolled Wollongong as part of the operation for the world titles held over the last eight days.
A NSW Police spokesperson said overall, officers were pleased with the behaviour of the thousands of spectators that came out to watch the world titles, with "majority doing the right thing".
However on Sunday, three arrests were made in separate incidents during the final men's elite race, including a 73-year-old man who allegedly intimidated a traffic marshal at a closed intersection.
Shortly after police searched the man's home and seized nine firearms and his firearms licence. He was charged with stalking and intimidation with intent to cause fear of physical harm.
Police also arrested a 58-year-old man after he entered a prohibited area related to the championships, and was charged with interfering with an amenity in major event area.
Another man, 35, was also arrested for entering a major event area and allegedly assaulting a police officer.
He was charged with entering a road closed to pedestrians without permission, assaulting a police officer in execution of duty, and resisting a police officer in the execution of duty.
The man was formally refused bail at Wollongong Local Court on Monday.
Before the men's elite race kicked off on Sunday, climate activists also took to the track to stage a protest and "draw attention to recent environmental destruction in the area".
Three people were approached by police, who seized their banner that read "coal mining in progress".
The protesters fled to the crowd and were not arrested.
Additional ambulance crews were also deployed across the race route and were on standby to treat spectators and cyclists if needed.
They were seen travelling on the course behind the peloton and received cheers from spectators as they followed the athletes.
"It took many months of planning and included careful coordination of our crews around road closures, to ensure we could reach patients without delay," NSW Ambulance Inspector Eamonn Purcell said.
"I'm incredibly proud of our local NSW Ambulance crews and their commitment to making this a successful event.
"This is a world class sporting event and we've showcased what our service can do to the whole world."
