Burger-mania is set to hit Australia again tomorrow, as the controversial American burger chain Carl’s Jr opens its first Australian store on the NSW Central Coast.

Carl’s Jr has set up shop in Bateau Bay near The Entrance, next to McDonald’s, and is offering a year’s worth of free burgers to the first 50 people through the door on Tuesday.

It’s a publicity stunt set to rival that of fellow US burger chain In-N-Out, which opened a four-hour pop-up restaurant in Surry Hills last month and sold out of product half an hour before the store opened.
