Meghan and Harry quietly slip out of Sydney after the Duchesss short-lived appearance at the Her Best Life retreat - as an inside look into the glamorous evening is revealed

The Duke and Duchess of Sussex have quietly slipped out of Sydney.

The couple left the Intercontinental Coogee Beach early this morning - before attendees at the Her Best Life retreat, an event in the same hotel where women had forked out $3,200 to spend time with Meghan - had even had their breakfast.

Meghan spent just two hours at the retreat on Friday night, where she posed for group selfies with select VIP guests and participated in a Q&A with Her Best Life podcaster Gemma O’Neill.

Despite Meghan’s short appearance, retreat participants gushed on social media that Gemma’s chat with the duchess was ‘incredible - so much kindness from Meghan’. Another said she had ‘goosebumps’.

High-profile guests included radio queens Jackie O Henderson and Carrie Bickmore, along with reality TV star Megan Towner.

On Saturday morning, the group was due to enjoy an optional yoga class at 7.45am before ‘easing into the day’ with a buffet breakfast.

But unbeknownst to the attendees, their star guest had already left the building. Harry and Meghan’s motorcade quietly slipped out of the Intercontinental’s underground car park at 7.20am.

They travelled in a small motorcade of one NSW police BMW and two glossy Range Rovers to the Sydney international airport.

Daily Mail understands they are booked on a 9am American Airlines flight to Los Angeles, where they will land Saturday morning California time and be reunited with their children, Prince Archie, 6, and Princess Lilibet, 4, at their mansion in California’s ritzy beachside Montecito.

Photos from the first night of the Her Best Life retreat in Coogee have revealed an inside look to the glamorous evening.

The night began with 'Bubbles in the Ballroom' and canapes before guests joined the Duchess for a three-course meal.

Attendees could choose between a Giramasa kingfish tostada or a Vannella burrata for entree, followed by the choice of a Riverina Angus beef tenderloin or free-range chicken breast for the main course.

Dessert was a choice of coconut crumble or the Aussie classic, pavlova.

But guests hopeful to catch one more glimpse of the Duchess of Sussex on Saturday will be bitterly disappointed, with Meghan and Harry making a dash for the airport.
