Bendigo Police Sergeant Rosie Rowe said one person was arrested for being drunk at the festival and the other for being drunk at the Bendigo Railway Station.

"We were really, really impressed with the crowd behaviour," she said. 

"With the number of attendees, we have got nothing but positives to say about everyone. 

"Everyone seemed to be enjoying themselves and the whole mood of the event was outstanding." 

Sergeant Rowe said 39 police members were stationed at the festival during the day. 

She said two people were arrested in Bendigo's central business district on Saturday night but she was unsure if they had been the festival. 

At the Bendigo Railway Station, Melbourne transit police used sniffer dogs to detect drugs on festival-goers. 

Acting Senior Sergeant Rob Howarth said patrons were well-behaved.

He said several people had been spoken to during the morning but would not provide further details.  

Christian's Bus Company Spring Gully manager Peter Ball said patrons who used the bus service to get to and from the festival were well-behaved. 

He said the service operated 35 buses from 9.30am to 11pm on Saturday, transporting about 10,000 people. 

"It went really well," he said. 

"We find with Groovin' the Moo they're a different type of behaviour group.

"Everyone (was) there to have a good day - there was no rush or tear."

He said patrons were picked up from the Bendigo Railway Station and caravans parks, and dropped off at the Bendigo Showgrounds. 

Mr Ball said buses picked up patrons when the festival ended, at 10.30pm, to take people into town. 

Central City Caravan Park manager Sharlene Kadar said behaviour of patrons was generally respectful. 

She said the caravan park was booked out, with more than 150 people sleeping in tents, swags and their cars. 

"In my park I felt it went all quite well," she said. 

"There was no major damage."

Ms Kadar said the festival was good for business.
