Post breakfast on day 4, begin driving towards Melbourne. On the way take a halt to visit Ballarat, the sovereign hill a Gold Museum. Get back in time, into the 1850s when affluent men and women, all dressed-up in the fineries and gold, walked down the street, showingoff their wealth. View the jaw-dropping collected of gold coins, artifacts and nuggets. Continue towards Melbourne. The evening is free for the activities of your interest. Stay overnight.
