The Campos driver found himself in potential hot water mere moments after the lights went out on Saturday in Albert Park.
As he pulled to the right to pass polesitter Roman Stanek, he failed to notice his fast-starting team-mate Pepe Marti and caused the Spaniard to collide with Invicta's Gabriel Bortoleto. Both drivers made heavy contact with the wall and retired on the spot while Hadjar continued to take the top spot on the podium.
