Threats to her family and the abject failure of a political statement on refugee detention has Yarrawonga woman Amber Holt feeling deep regret for her "stupid and selfish" attack on Prime Minister Scott Morrison.

It was revealed in Albury Local Court on Tuesday that Holt had mental health issues leading up to and since the May 7 egging, forcing her to quit her job.

"I don't encourage anyone to follow what I did. It's just caused more drama," she said outside court just minutes after she was convicted of assault and sentenced to an 18-month community corrections order.

Holt, 25, said the repercussions of that one act, to which she accepted she didn't give enough thought, had been drastic.

"It's led to a lot of insults, a lot of threats to my family and loved ones, (to) myself. I've had a lot more attention than I've ever had in my life and it's not been great."

Holt must complete 150 hours of unpaid community service over the assault conviction and was convicted and fined $150 for possessing 0.3 grams of cannabis.

Open and apologetic and occasionally emotional, Holt later accepted that her sentence for throwing the egg during the CWA state conference in Albury was "a fair call".

Much of the sentence hearing was taken up with submissions from prosecutor Sergeant Andrew Coombs and defence lawyer Dominic Holles on whether the assault charge was aggravated by the fact the victim was a public elected official.

Mr Brender adjourned the matter for an hour to give this closer consideration.

When he resumed, he said it was essentially the job of the police to decide on the nature of the charge, not the court.

Mr Brender said the common assault charge laid against Holt, which named Mr Morrison and his role as prime minister, did not in essence incorporate elements of a similar Commonwealth charge that allowed for the greater seriousness of an attack on an elected public official.

He took into account the circumstances of Holt's actions, but the charge did not inherently infer a degree of aggravation just because the prime minister was the victim.

Nevertheless, Mr Brender said what Holt did was "a more serious example of the offence" and one carried out for political reasons as she wanted to "embarrass" Mr Morrison.

"It was motivated by a dislike of a person she didn't know."

While Holt decided on the attack after hearing of Mr Morrison's visit on her car radio, Mr Holles said what Holt did "is well short of a sophisticated degree of planning" when compared with "organised criminal activities".
