The court was told Evan Heller, 34, had been drinking at a Ballarat venue in November last year when he was arguing with patrons and asked to leave by security.

He asked to say goodbye to his colleagues and found himself in another altercation.

Representing himself, he said the security guard had painfully twisted his arm to escort him out of the building, which led to him retaliating.

The security guard went to hospital but there were no injuries.

He pleaded guilty, but argued in court that the venue should have stopped serving him under the Responsible Service of Alcohol licensing as he could not remember the incident.

Magistrate Gregory Robinson said Heller should take responsibility for himself.

"You wouldn't want someone to headbutt you at your work," he said.

A 22-year-old avoided conviction after a police warrant executed on her house in Ballarat found a cache of drugs.

Police found small quantities of cannabis, cocaine, ketamine, amphetamine, ecstasy, and a variety of pills, including 16 Xanax and 20 Endone.

Police interviewed the woman and asked for her to hand over the PIN for her phone, to continue an investigation - she refused, fearing retribution.

At the Ballarat Magistrates' Court, her defence lawyer noted she had completed Court Integrated Service Programs and extensive drug testing, had returned to university, and was the carer for her younger brother.

She had no priors and had pleaded guilty early.

"Read as a collective, (the list of drugs found) sounds like a lot," her lawyer said.

While Magistrate Gregory Robinson noted her remorse and handed her a 12-month adjourned undertaking, without conviction, he did grant police an order to take a forensic sample which will put her DNA on the record.

Her lawyer protested this decision, saying it was not an appropriate charge for the order, but Mr Robinson replied she would have "nothing to fear".

"It will make sure she's not involved in future cases - it's in the public interest to have as many samples as possible for crime detection," he said.

A Ballarat woman was lucky to escape a more severe punishment after she was intercepted drink driving the day after her community corrections order lapsed.

The Ballarat Magistrates' Court was told Charlotte Sharp was spotted driving in Delacombe in June, and a police breath test found a blood alcohol reading of 0.111.

While her defence lawyer said she had not driven since the incident, this had resulted in her losing her job.

Sharp pleaded guilty, and Magistrate Gregory Robinson fined her $800 with conviction.

A 42-year-old Golden Point man was convicted and fined $500 for stealing a letter from a person's mailbox.

The Ballarat Magistrates' Court was told Brett Head and a pair of co-accused drove to an Alfredton address and removed the letter.

There was some confusion as to the relation of the victim to the accused, however Head was handed the letter, kept it, and made no attempt to return it.

"This is quite a weird set of circumstances," Magistrate Gregory Robinson said.

"It's not your property to take, you can't interfere with people's mail."

A man caught driving while suspended twice on the same day was convicted and fined $2500 at the Ballarat Magistrates' Court on Monday.

The court was told Dylan Psaila had lost his license in July 2018 because of demerit points.

He was first intercepted in July, and said he didn't know he had been suspended.

However, on October 18, he was intercepted at 1.36am and 5.30pm - both times he said he didn't know he was suspended.

Magistrate Gregory Robinson said he would give Psaila the benefit of the doubt for the July offence, but was not impressed by the October offences.
