A Married At First Sight star has faced court for threatening to kill his nephew and former business partner during a heated dispute.

Tony Mojanovski, 54, owned a fishing charter business with his nephew, and in November 2025, called to discuss the business.

Court documents revealed that the conversation 'quickly turned volatile' when Mojanovski's nephew said he couldn't attend work that day, the Illawarra Mercury reported.

The reality star reportedly threatened his nephew with physical harm, prompting the victim to record the conversation using his wife's phone. 

In the audio, Mojanovski was heard saying: 'I'm gonna kill you, ya c***.'

The victim reported the matter to police and Mojanovski was later arrested and taken to Illawarra Police Station, where he initially denied the allegation.

During an interview with police, Mojanovski said he did not remember making the threats but retracted his story after hearing the victim's recording, telling police: 'There you go, that's what I said.' 

Appearing in Wollongong Local Court on Wednesday, Mojanovski pleaded guilty to intimidation.

He avoided a conviction and was placed on a conditional release order to be of good behaviour for one year.

Mojanovski told the court that he regretted his actions.

'It's just a mistake I made,' he said. 'I'm not an aggressive person, I've never been in a fight.

'He just pushed me to my limits.'

Judge David Williams accepted that Mojanovski was not a violent person and was otherwise a man of good character.

Mojanovski declined to comment when contacted by Daily Mail.

It comes after Mojanovski was rushed to hospital in April last year after suffering a heart attack.

He underwent emergency surgery, with doctors performing a coronary artery bypass graft to treat the blockage and save his life. 

Speaking to Daily Mail Australia from his hospital bed, Mojanovski said he was in a stable condition and feeling much better after the terrifying ordeal.

'Luckily I went straight to the doctors,' he explained. 

'During the week I wasn't feeling well. It has been happening for a long time – I was just feeling not right, like something was on my chest every now and then, giving me heartburn and stuff like that.'

Mojanovski said the persistent symptoms eventually became too much to ignore.

'I felt a bit off too. That's why I thought, you know what, I'm going to take it easy this week because it was just too much,' he said.

Reflecting on the health scare, he admitted it was 'pretty scary' and revealed there could be a family link to heart issues.

'My mum passed away from an aneurysm,' he said, adding that smoking, stress and partying may have contributed to his health decline.

'I was smoking, the cigarettes, the stress, being on the boat, partying – just too many things. It caught up with me, mate,' he admitted.

He said he planned to slow down and prioritise his health moving forward.

Mojanovski rose to fame on the 2025 season of Married At First Sight, where he was paired with Morena Farina.
