Thanks, all. The penguins are on our list if we have time ... most of our Melbourne time will be spent roaming with Oz as he shows us what he likes of the city, along with an epicurean day trip to the Yarra Valley (

Our "must sees" in Sydney are the bridge climb and the opera house. We also hope to do a harbor cruise.
