Maccas is doing this absolute SERVICE to the people as it's International Burger Day.
To get your free burger, customers will need to install the mymacca's app and check the tab labeled 'My Rewards'. Present your phone at the counter and you will get that FREE, tasty goodness.
One burger per customer is the limit.
Sharon Paz, McDonald's Australia vice president has told 7NEWS.com.au that the news follows the change in how Macca's are cooking their meat patties. She says that the meat is now cooked for 40-seconds making it the "juiciest meat that our customers have ever tasted."
Onions will now be cooked on the same grill as the meat to give it extra flavour, extra sauce will be added onto each Big Mac and cheese will be melted more "perfectly."
So, what are you waiting for? RUN DON'T WALK!
