Alice Springs has the same problems as anywhere else when people cannot responsiblly control their alcohol intake.
Fortunately for you most of the inherent violence is directed towards their fellow community members and family.
Alice Springs Aboriginal communities have even gone to the stage of erecting fences and installing gates and you cannot gain access or remain in the compound unless dry and sober to protect themselves.
Kathy lived and worked in Alice Springs for year at the Novetal and cycled to work everyday at odd hours like 5am at night after midnight and never had any issues even though she went along the Todd River, but yes she took precautions whilst doing so.
I wouldn't not go to Alice Springs becasue of a TV show, l would merely take the appropriate precautions for your personal safety.
What is unfortunate it is not a new problem and l came across this issue of drunknesses and violence on my first visit to Alice Springs in 1978 and it was prevelant then. Government both Territory and Federal have failed to address the issue within the Aboriginal community, Government policies of housing, social welfare have actually contributed to the issues in my opinion and we have wasted billions of dollars funding Aboriginal communities on the bases of white middle class values, myths and social guilt trips.
