Wearing a maroon jacket, Holmwood was expressionless as sheriffs led him from the court room.
The 33-year-old had been slated for sentencing last week but never showed.
His lawyer, Will Tuckey, had pushed for a non-custodial or suspended sentence.
But the magistrate said he considered jail the only appropriate option for the serial streaker, who got his kit off in 2011 at a Warriors vs Tigers match at Leichhardt in Sydney's inner west.
"In the circumstances of totality, bearing in mind the breach of bond as well as the offence that constituted the breach of bond, I do come to that conclusion,'' Mr Longley told Burwood Local Court.
Holmwood could have been slapped with a maximum jail term of 18 months.
The court heard the offender was of "limited'' intelligence and his latest public nude run had damaged his already-strained relations with family.
"This is a gentleman with complicated needs, he's had a great deal of media attention, he's been publicly humiliated,'' Mr Tuckey said.
The lawyer, who indicated he would appeal the sentence, said the Origin streaking was a victimless crime viewed by many as a "comic'' incident.
"It would be hard to find a person who was particularly offended on that night,'' he said.
"There's no evidence of anyone being traumatised by the action and there's no evidence of any ongoing harm.''
Holmwood is expected to apply for bail once his appeal is lodged.
