In a statement, the fast food chain said: 'The Grand Big Mac burger is packed full of all the classic Big Mac ingredients but with more special sauce over two larger 100 per cent Aussie beef patties, with more lettuce, cheese, and onions, all served on a larger sesame seed bun.'
'We’re excited to be celebrating 50 years of the Big Mac, one of Macca’s most popular burgers here and around the world. To celebrate this special occasion we’re introducing the limited edition Grand Big Mac — giving our customers more of what they know and love,' McDonald's Australia marketing director Jo Feeny said.
The Grand Big Mac will be available across McDonald’s restaurants nationwide for a limited time only.
FYI - when released in the UK, this special edition burger supply sold out in THREE days nationwide.
