Having lived in the area until recently I giggle at some of the comments above.
Yes there is a drug problem in town, but while I was there I never had anything broken into or stolen.
There is plenty of money in Mildura and the town really enjoy their motorsports, whether it be speedway, open wheeled racing, Hattah desert race, or power boats, all motorsports are well supported.
Too far.. it's 3.5hrs from Adelaide, 3hrs from places like Broken Hill, Hay and Various Victorian towns. People will travel for this type of attraction. It also has an airport.
