The royal couple spent 6 hours in Melbourne Wednesday. One of the highlights of the day was a tram ride, the Sydney Morning Herald reported.
The queen and her husband were joined by Ted Baillieu, the premier of the state of Victoria, and his wife for a spin along St. Kilda Road. While the tram is a public conveyance, members of the public were not invited to join the queen.

The royal couple arrived in Australia last week and have spent most of their time in the capital, Canberra, with a day trip to Brisbane. The visit is the 85-year-old queen's 16th to Australia.
