Mehajer, 31, was due to face a three-day hearing this week after he was charged with throwing an EFTPOS machine at taxi driver Nazir​ Syed's face early on April 2, 2017.

The action left the driver with an injury to his nose. Mehajer was also accused of stealing Mr Syed's phone and destroying a woman's iPhone 7.

When the matter was mentioned at Downing Centre Local Court on Monday, Mehajer entered guilty pleas to assault occasioning actual bodily harm and destroying or damaging property.
