3. Sample local produce
Adelaide's 145-year-old Central Market - the largest undercover market in the Southern Hemisphere with more than 250 stalls - is a foodie institution, and many of the stalls offer samples of their wares. A trip to South Australia would also not be complete without a visit to a winery or two, many of which have free tastings.
4. Get on board
Buses and trams in the square mile are free, so you can go from attraction to attraction, including the Central Market, East and North Terrace areas, Rundle Mall (the main shopping strip), the railway station, squares and gardens easily at zero cost.
5. Surf the web
Auckland, take note - there is free internet everywhere in Adelaide, so you can surf your ass off. It's at the airport, on public transport, in the city centre, in department stores and supermarkets, and in almost every bar and eatery.
