MAFS Australia star Sebastian Guilhaus arrested after police allegedly found 1kg worth of meth in his home

Former Married at First Sight star Sebastian Guilhaus has been arrested by Serious and Organised Crime Branch detectives at his Adelaide home.

The 35-year-old is on remand and has been charged with drug trafficking, after a police raid at his Croydon home.

Officers allegedly seized almost a 1kg of methamphetamine, which has a street value of at least $90,000.

Serious and Organised Crime Branch Detective Superintendent Billy Thompson said it was a significant amount of illegal substances.

"Methamphetamine causes terrible harm to users and to our communities," Thompson said.

"This seizure is a significant amount and would have a street value of approximately $90,000. Those who traffic illicit drugs in these amounts do so purely for their own greed, they have no care for others."

According to The Advertiser, he appeared in the Adelaide Magistrates Court late on Friday (July 28), charged with one count of trafficking in a commercial quantity of methamphetamine.

He was remanded in custody to appear for a bail hearing later this week.

In 2020, Guilhaus appeared on the seventh season of Married at First Sight and was matched with returning fan favourite bride Lizzie Sobinoff.

The pair left the show together before splitting up a year later.

Before joining the show, Guilhaus played 48 games in the South Australia National Football League.

In the time since MAFS has ended, Guilhaus launched a wellness and fitness coaching business and has grown a 90,000-strong Instagram following.

In 2021, he was named one of Adelaide's 'most eligible singles'. He describes himself as an 'athlete/creator/thought provoker' online.

He has also joined OnlyFans and recently collaborated with fellow MAFS alumni Hayley Vernon.

Vernon defended Guilhaus in the comments after he shared the news on Instagram.

"Seriously the amount of hate @seb is coping is not unbelievable, I actually get it! Most of these people fell in love with a one dimensional version of Seb that was shown through the a TV camera - and that was heavily manipulated to not actually show Seb's true persona - he's far more complex, funny, witty, strong and multi-faceted and the fact you are ripping him down says an awful lot more about yourselves than him - let the man do what he wants," she wrote.

"Fancy going out of your way to spread hate to someone you like or dislike off a TV show - you like a character - you don’t even know the real man - boot off."
