Meghan's clothing choices of the likes of Dion Lee and Karen Gee have also caused the sites to fall, in a phenomenon known as the Meghan Effect.

The & Other Stories dress selected by the 37-year-old duchess on Monday was a perfect choice for the warm climate of Queensland.

With a pointed collar, tight waist and tie at the waist, the design was complemented perfectly with the sandals "Grear" Meghan by Sarah Flint.

Sarah Flint flats have quickly become an option for royalty, which has allegedly used the New York-based label more than 20 times.

Meghan finished the polished but relaxed look with sunglasses from New Zealand designer Karen Walker.

Just over a week into her 16-day adventure with her husband, Prince Harry, Meghan has not been disappointed, dazzling in a series of high-end sets of renowned designers.

He has also paid tribute to his first host country by supporting Australian labels such as Dion Lee and Martin Grant.

Among her sartorial selections, Meghan has given her approval to high-profile friends such as tennis star Serena Williams and Australian jewelry designer Natalie Marie, as well as lesser-known brands.

Meghan has included a few other relatively affordable pieces in the mix, including a white Maison Kitsune shirt for $ 83 (£ 40), a pair of jeans for $ 199 (£ 140) and a black Club Monaco dress that costs $ 597 (GBP £ 325).

The 37-year-old woman has also been seen recycling several of her outfits, including a Martin Grant raincoat and a pair of Stuart Weitzman pumps that have had two exits so far.

But despite this effort, Meghan's wardrobe options have already shot at thousands.

The Duchess intends to take a back seat during the events on Fraser Island on Monday, after a grueling first week of the actual tour.

Their Royal Highnesses are visiting Fraser Island or Kyria, as it is known by the Traditional Owners of the Butchulla people, as part of the dedication of the site to the Commonwealth Queen's Pavilion (QCC).

The QCC creates awareness of indigenous forests and allows Commonwealth countries to exchange knowledge and ideas on best practices for forest conservation.

During their stay on the island, the couple will settle in the luxurious Kingfisher Bay Resort, which has secluded beach houses, wooden huts surrounded by shrubbery and eco-friendly hotel rooms.

The expectant Duchess of Sussex will give up her royal duties during the day due to the rugged terrain of the island, but there will be many things to do even as a tourist.

Kensington Palace has confirmed that Meghan will spend Monday relaxing at the resort, where the couple will spend the night, but is expected to be well enough to meet and greet the public in the afternoon.
