The woman who threw an egg at Prime Minister Scott Morrison during the federal election campaign has pleaded guilty to common assault.

Amber Holt, 24, was charged with common assault and possession of marijuana following Mr Morrison's visit to the Country Women's Association state conference at the Albury Entertainment Centre on May 7.

In a tearful appearance at Albury Local Court today she admitted common assault.

Holt was also due to be sentenced on today but the matter was adjourned for two weeks to allow the prosecution and defence time to consider the actual "harm" of the assault.

Magistrate Imad Abdul-Karim noted there was a similar commonwealth offence that encompassed an assault on an elected public official.

The magistrate said that appeared to be of far greater seriousness than the meaning of an assault under NSW law.

"The difficulty I'm having trouble handling (is) the gravity of the offending," he told the court.

Mr Abdul-Karim insisted there "no place for violence" in the community but especially during a political campaign.

Holt had invested a great deal of planning into her offending after she discovered Mr Morrison was going to be in Albury, the magistrate said.

She went to a supermarket to buy eggs specifically to carry out the assault.

Before adjourning sentencing to July 23, the magistrate explained to Holt - who'd occasionally sobbed during today's hearing - why he was doing so.

"I understand your honour," she said. "Thank you."

Holt previously pleaded guilty to possessing cannabis.

Later when Holt left the court she apologised for throwing the egg when approached by 9News journalists.
