Harry and Meghan's Australia Tour

The Duke and Duchess of Sussex began their Australian trip with a visit to the Royal Children's Hospital in Melbourne, a stop that many observers noted honored the legacy of the late Princess Diana.

While the couple is traveling as private citizens, the tour features a familiar mix of charitable advocacy and commercial interests, including meetings related to Meghan's lifestyle brand, As Ever.

Advocates have praised their focus on veteran support and community welfare, but critics have raised concerns about the cost of security and the 'faux-royal' nature of the engagements.

The couple is scheduled to continue their visit with stops in Canberra and Sydney later this week.
