Robbie served as a bridesmaid alongside three of her close friends as the couple tied the knot in an outdoor ceremony in the Byron Bay Hinterland.

In videos posted to social media, Robbie is seen giving a speech at the reception, saying

“we are some of Anna’s oldest and dearest friends”.

The bridesmaids wore cowl neck gowns from Australian label Bec + Bridge, which retail for $300.

In February, the 28-year-old Oscar nominee took a break from filming Harley Quin spin-off Birds of Prey in Los Angeles to attend MacKillop’s hen’s party in Byron Bay before returning to the US.

Robbie returned to Queensland early this month to attend the burial of her late grandmother, Verna, 92, affectionately known to Margot and her siblings as “Narnie’’, in Dalby.

She then spent time travelling through the Northern Territory as well as slipping into Adelaide late last week before returning to the Gold Coast.

Overnight, Robbie was also announced as the newest ambassador for Chanel Fragrances, broadening her relationship with the luxury fashion house.

Just days after the wedding Robbie jetted out to Cannes, set to walk the red carpet this morning for the premiere of her latest film, Quentin Tarantino’s Once Upon A Time in Hollywood, in which she plays late actress Sharon Tate.​
