Harry and Meghan: Sussexes arrive in Australia for four-day tour

The Duke and Duchess of Sussex, Harry and Meghan, have arrived in Australia for a four-day tour that combines visits to charitable causes with commercial engagements. They will meet patients at a children's hospital, military veterans, and survivors of family violence. Harry is set to give a keynote speech at a summit in Melbourne, while Meghan will participate in a women-only event in Sydney. The trip is privately funded, but questions remain about the cost of security for Australian taxpayers.
