Harry and Meghan visit Australia

Prince Harry and Meghan Markle have arrived in Melbourne for a four-day, privately funded visit focused on community welfare and mental health initiatives.

The trip, which includes visits to a children's hospital and a veterans' art museum, has sparked debate over its 'quasi-royal' nature and commercial implications.

While supporters have praised the couple's focus on charitable causes, a petition over the cost of policing the tour has gathered more than 45,000 signatures.

The visit also coincides with Meghan's trademarking of several products in Australia for her lifestyle brand, As Ever.
