Joe El-Ajouz, owner of Ambrosia On The Spot, said it took 24 hours to create the burger, including 12 hours just to cook the patty, and it required four men to flip, The (Sydney) Daily Telegraph reported Monday.
"I've always wanted to break a world record and this is a bit of fun and a marketing tool to get people in here and get them talking," El-Ajouz said.
The patty was topped with 16 tomatoes, 120 slices of cheese, four pounds of lettuce, a pound of barbecue sauce and placed between 46 pounds of bread.
The previous record holder for the world's largest burger was made in the United States and weighed 185 pounds.
