The man who ran naked onto the field during this year's third State of Origin match has been sentenced to three months in jail.

Wati Holmwood bared all in the final moments of the series decider at Sydney's ANZ Stadium in July.

He pleaded guilty to indecent exposure and running onto a playing field without authorisation.

Holmwood, who was on a good behaviour bond for streaking at an NRL game last year, was due to be sentenced last week but did not attend the hearing at Burwood Local Court.

Holmwood's lawyer told the court his client has limited intellect and is somewhat distanced from his family.

He said the 33-year-old did not attend court last week because the media attention had made him confused about the date.

The defence said Holmwood has no phone and no real grasp on the passage of time.

Magistrate Christopher Longley sentenced him to three months jail for breaching two good behaviour bonds, as well as the charges relating to the State of Origin streak.

The defence pushed for a suspended sentence but the magistrate refused.

Holmwood, who was also fined $2,000, has lodged an appeal.
