The best parts of Melbourne are actually within 3 km of the CBD, the day trips and excursions are not the highlight of Melb for me. Note the Great Ocean Road was closed recently due to mud slides in heavy rains, not sure if there is any longer term impact. Yarra valley wine tasting is great for wine tasting, kind of like Napa was in the glory days of the 70s before it became soooo commercialized and overrun with tourists
