Meghan pulled out of a planned appearance at the cycling time trial on the first day of the Invictus Games in Sydney.
Kensington Palace said her schedule was being "cut back" after a busy schedule.
“After a busy programme, The Duke and Duchess have decided to cut back The Duchess’s schedule slightly for the next couple of days, ahead of the final week-and-a-half of the tour," the Palace said.
However Meghan beamed in front of the cameras as she and Prince Harry attended a reception hosted by the Prime Minister of Australia at The Pavilion Restaurant on Oct. 21.
The Duchess wore her brunette hair up and looked casual in skinny jeans, a white blazer and a roll neck black top.
She sported black sling back shoes and an elegant bag.
"The ensemble is perfect," fashion expert Donny Galella told New Idea.
"The on trend double breasted pinstripe jacket with turtleneck, black skinny jeans and that handbag - is just divine.
It's a similar outfit to what she wore yesterday, but I much prefer this look," he added.
