Around 5pm on Saturday police were called to CBUS Stadium after reports of an assault by a spectator on an official.

They say the 27-year-old from Bilinga gained entry to the field of play at the conclusion of the match and threw a punch at the referee, just grazing him.

He has been charged with entering the playing arena of a stadium by police, while the referee has issued a common assault complaint against the man.

Acting Chief Superintendent Rhys Wildman says there is no place in the community for such actions.

"That is an extremely concerning matter for us. Having anyone interfere with a sporting official is considered extremely serious," he said on Sunday.

"Obviously the stadium and the NRL may take action in relation to that person's attendance at future venues, that's for them.

"I understand people like supporting their particular sports, and be encouraged to do so. However, this is not something to take that sort of level of action to actually jump the fence and assault an official."

The man has been issued a notice to appear in the Southport Magistrates Court in November.
