 There are a number of officially demarcated areas which are similar, but all differ slightly.Some that are larger still use the term 'Melbourne', which leads to some confusion.The boundaries of the Australian Bureau of Statistics (ABS) Statistical Area Level 2 'Melbourne' is a good representation of the commonly understood area of 'the CBD'; it includes the Hoddle Grid, plus the area of parallel streets just to the north up to Victoria Street including the Queen Victoria Market, but not the Flagstaff Gardens or the streets to the west of it, and the area between Flinders Street and the Yarra river west of Swanston Street.
