Basic was sentenced to 70 hours community service and disqualified from driving for three months, 9 News reports.
The magistrate reportedly gave her a stern telling off over her rationale for committing the offences, which was: "I would never drink and drive, but the bitch pissed me off".
Cameras at the Cleveland Magistrates Court caught the 29-year-old's dramatic arrival; she turned up in a limousine, with a feisty bodyguard who ordered photographers around.
Basic is one of the many 2019 MAFS AU participants who cheated on her partner with someone else's on the show.
She appeared to spend the night with Elizabeth Sobinoff's husband Sam Ball, shortly before dumping her own spouse, Bronson Norrish.
