Opening in January 2025, the store is described as an "interactive experience" where fans can meet the M&M's characters Red and Yellow, take photos and indulge in the iconic chocolate wall.
The store will operate for the three weeks of the Australian Open and will also offer merch and two exclusive AO shades of M&Ms - pink and light blue.
The multi-year partnership will see M&M's named as the Official Confectionery Partner of the Australian Open.
Mars Wrigley's Portfolio Director Michelle Gazzola said the immersive experience would bring M&M's "colourful fun" to life.
"This is the first time we've done anything of this scale in Australia, and we're excited to share this journey with Australian Open fans. We can't wait to bring a vibrant, inclusive, and joyful activation to this iconic event and make M&M's history in Australia."
The store will be open from January 6th - 26th, 2025.
