The only 2 things that I can remember for Melbourne is the good food and shopping at the Queen Victoria Market(mix of all cultures) and the trip around the Great Ocean Room... nice view of the ocean... good beach to relax (some areas have calm beaches whereby wave is not too strong) I guess you can show down you pace of life... as for kids I can't think of what they can do or like to do there.
