We arranged the tour ourselves. Taste of Barossa. It was a small bus tour. Our bus drive was Dallas, the owner. The tour lasted all day and he took us to four wineries with lunch included. Wonderful tour.
In Adelaide, the port is a ways from the city center.
Went on our own. Bought an all day bus ticket at port terminal for $7.80. Lots of visitor center personnel on the dock to help you. Visited Skydeck, $17.50. Took a river cruise on the Yarra river for $25.00(2hours). We rode the free visitor bus around the city and then took the "maroon" #109 West/Port on Collins Street to get back to the ship.
Dunedin, New Zealand: Docked in Port Chalmers. Scottish settlement. Took the Natures Wonders Argo tour. Fantastic and saw lots of wilflife. It was located on the Otago Peninsula. Be sure to get your passport stamped on the return to the ship for New Zealand. Cadbury Chocolate is made here.
